Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Muni 
Funds-Limited Term Portfolio ("Fund") for the period ended September 30, 1998.
In this report, we summarize the period's prevailing economic and market
conditions and outline our portfolio strategy. A detailed summary of the Fund's
performance can be found in the appropriate sections that follow. We hope you
find this report to be useful and informative.


Performance Update

For the six months ended September 30, 1998, Class A and L shares of the Fund
had a total return of 4.47% and 4.39%, respectively. In comparison, the Lipper
Analytical Services, Inc. peer group average returned 3.92% for the same period.
(Lipper is an independent fund-tracking organization.)

We are proud to report that the Fund has received a five star rating overall
from Morningstar, Inc.(*) as of September 30, 1998. Over the six months covered
by the report, the Fund distributed income dividends totaling $0.17 per Class A
share; based on its net asset value ("NAV") of $6.89 as of September 30, 1998,
this equates to an annualized distribution rate of 4.88% for Class A shares. For
an individual in the federal income tax bracket of 36%, the Fund's tax-free
yield of 4.88% is equivalent to a taxable yield of 7.63%.

     Morningstar ratings are calculated from the Fund's 3- and 5-year returns
     (with fee adjustments) in excess of 90-day T-bill returns. The 1-year
     rating is calculated using the same methodology, but is not a component of
     the overall rating. The Fund received 5 stars for the 1- and 5-year
     periods. It was rated among 1,581 and 943 intermediate municipal bond funds
     for the 3- and 5-year periods, respectively. Ten percent of the funds in a
     rating category receive 5 stars. Different classes share a common portfolio
     of securities.

Market and Economic Overview

The municipal bond market has continued to benefit from the U.S. economy's
persistent strength. We expect this year's municipal bond issuance to be heavy
and come close to the record set in 1993, a year when approximately $290 billion
in new debt was issued. Attractive low rates combined with the ongoing
infrastructural needs of many municipalities are, in our view, some of the
reasons why so many municipal bonds have been issued lately.

Attractive low interest rates have been an incentive for state and local
governments to refinance older, high interest rate debt. In addition, when
interest rates are low, it is easier to get voter approval to fund ongoing
infrastructure construction such as school and healthcare facilities.

The globalization of the U.S. economy has made it more vulnerable to foreign
difficulties. In our opinion, the dominant theme in the financial markets
continues to be what impact, if any, will Asia's and Russia's problems have on
the U.S. economy and future corporate earnings. During the reporting period,
strong demand for U.S. Treasuries was fueled by a classic flight to safety
amidst rising investor uncertainty. While municipal bond prices have been mostly
flat, the prices of U.S. Treasuries have gone higher and their yields have
declined to historic levels. Tax-exempt bonds have participated in this rally,
albeit at a somewhat subdued pace.

With stock market volatility on the rise and anxiety about the global economy
increasing, the Federal Reserve Board ("Fed") changed its monetary policy from
one of vigilance against inflation to one of combating deflation. (Deflation is
when prices actually fall. Deflation should not be confused with disinflation.
Disinflation is the slowing down of the rate at which prices increase.) The
Federal Open-Market Committee, the committee that sets interest rate and credit
policies for the Federal Reserve System, lowered the federal-funds rate 25 basis
points on September 29, 1998. (A basis point is a means of expressing yield as a
percentage. Each basis point is 1/100 of 1%. The federal-funds rate is an
overnight bank lending rate that is a benchmark for other short-term interest
rates.) After the close of the reporting period, the Fed took an unexpected
action of cutting short-term interest rates again by another 25 basis points on
October 15, 1998. The second Fed rate cut came as a surprise to many investment
professionals.

We think that the tax-exempt market, which has been lagging versus the U.S.
Treasury market in 1998, should experience stable to lower interest rates as

municipal bond volume slows in the coming year. Moreover, we believe the
after-tax attractiveness of municipal bonds should become more apparent to
individual investors in the days ahead.


Investment Strategy

The Smith Barney Muni Funds - Limited Term Portfolio is an intermediate-term
municipal bond fund that seeks to provide investors with as high a level of
current income exempt from federal taxes as is consistent with a prudent
investment approach.

The Fund invests primarily in high-grade municipal securities with maturities of
less than ten years. Because we are positive on further rate cuts, we have
maintained a 9 1/2 year to 10-year average weighted maturity. One of our goals 
in the Fund is to deliver the performance of a longer-maturity fund with less
market volatility. We believe the combination of intermediate-term securities
and the Fund's high-grade credit quality orientation should help to reduce
credit risk and NAV price volatility, while still maintaining a competitive
dividend yield for our shareholders.

As of September 30, 1998, the Fund's average weighted maturity was 9.9 years.
The Fund's largest holdings were concentrated in general obligation bonds
(16.7%), hospital bonds (16.3%) and transportation bonds (11.7%).

Approximately 93% of the Fund's holdings were rated investment grade (BBB/Baa
and higher) by either Standard & Poor's Corporation or Moody's Investors Service
Inc. at the end of September. (Standard & Poor's Corporation and Moody's
Investors Service Inc. are two major credit reporting and bond-rating agencies.)
Because of new construction initiatives in the U.S., we remain bullish on select
transportation issues. In addition, other areas of the market we particularly
like for the next six months are healthcare and utilities issues that fall in
the five- to twelve-year maturity range. The electric utilities sector
especially looks favorable to us because of the deregulation of the
industry, which has created overlooked opportunities in this sector.


Municipal Bond Market Outlook

Going forward, we are optimistic about the attractiveness of the tax-exempt bond
market. We expect that the Fed will lower interest rates at least one more time
in 1998, and if the U.S. economy remains sluggish, we believe that the Fed will
lower rates again in the first half of 1999. We expect a moderately expanding
U.S. economy while the Fed continues to monitor the U.S. economy closely for
signs of either inflationary or deflationary pressures. While the ultimate
effect of the worsening Asian and Russian crisis remains unknown, municipal
bonds are yielding almost as much as U.S. Treasuries,

giving investors tax-exempt income with a competitive yield. At current levels,
we believe that tax-exempt securities represent good relative values.

On a more somber note, we report with much sadness the passing of Emeritus
Trustee C. Richard Youngdahl. Dick made many valuable contributions to the Board
and the Fund during his tenure and he will be missed.

In closing, thank you for investing in the Smith Barney Muni Fund - Limited Term
Portfolio. We look forward to continuing to help you pursue your financial
goals.

+  Hypothetical illustration of $10,000 invested in Class A shares at inception
   on November 28, 1988, assuming deduction of the maximum 2.00% sales charge at
   the time of investment and reinvestment of dividends (after deduction of
   applicable sales charge through November 6, 1994, afterwards at net asset
   value) and capital gains, if any, at net asset value through September 30,
   1998. The performance of the Portfolio's other classes may be greater or less
   than the Class A shares' performance indicated on this chart, depending on
   whether greater or lesser sales charges and fees were incurred by
   shareholders investing in the other classes.

   All figures represent past performance and are not a guarantee of future
   results. Investment returns and principal value will fluctuate, and
   redemption values may be more or less than the original cost. No adjustment
   has been made for shareholder tax liability on dividends or capital gains.

*  It is the opinion of management that the Lehman Brothers Municipal Bond Index
   and the Lehman Brothers Municipal 10-Year Bond Index are more appropriate
   broad-based benchmarks for the market in which the Limited Term Portfolio
   invests rather than the Lehman Brothers Municipal Long Bond Index and the
   Lehman Brothers Municipal 5-Year Index. In future reporting, the Lehman
   Brothers Municipal Bond Index and the Lehman Brothers Municipal 10-Year Bond
   Index will be used as a basis of comparison of total return performance
   rather than the Lehman Brothers Municipal Long Bond Index and the Lehman
   Brothers Municipal 5-Year Index. The Lehman Brothers Municipal Long Bond
   Index (consisting of maturities of at least 22 years), the Lehman Brothers
   Municipal 5-Year Bond Index (consisting of maturities of 4-6 years) and the
   Lehman Brothers Municipal 10-Year Bond Index (consisting of maturities of 10
   years) is each a sub-index of the Lehman Brothers Municipal Bond Index, a
   broad-based, total return index comprised of investment grade, fixed rate
   municipal bonds selected from issues larger than $50 million issued since
   January 1991. Each index is unmanaged and is not subject to the same
   management and trading expenses of a mutual fund.

Bond Ratings (unaudited)
================================================================================

All ratings are by Standard & Poor's Ratings Services ("Standard & Poor's"),
except that those which are identified by an asterisk (*) are rated by Moody's
Investors Service Inc. ("Moody's") and those which are identified by a double
dagger (++) are rated by Fitch Investors Services, Inc. ("Fitch"). The
definitions of the applicable rating symbols are set forth below:

Standard & Poor's -- Ratings from "AA" to "BB" may be modified by the addition
of a plus (+) or minus (-) sign to show relative standings within the major
rating categories.

AAA    -- Bonds rated "AAA" have the highest rating assigned by Standard &
          Poor's. Capacity to pay interest and repay principal is extremely
          strong.

AA     -- Bonds rated "AA" have a very strong capacity to pay interest and
          repay principal and differ from the highest rated issue only in a
          small degree.

A      -- Bonds rated "A" have a strong capacity to pay interest and repay
          principal although they are somewhat more susceptible to the adverse
          effects of changes in circumstances and economic conditions than bonds
          in higher rated categories.

BBB    -- Bonds rated "BBB" are regarded as having an adequate capacity to
          pay interest and repay principal. Whereas they normally exhibit
          adequate protection parameters, adverse economic conditions or
          changing circumstances are more likely to lead to a weakened capacity
          to pay interest and repay principal for bonds in this category than in
          higher rated categories.

BB     -- Bonds rated "BB" have less near-term vulnerability to default than
          other speculative issues. However, they face major ongoing
          uncertainties or exposure to adverse business, financial, or economic
          conditions which could lead to inadequate capacity to meet timely
          interest and principal payments.

Moody's - Numerical modifiers 1, 2 and 3 may be applied to each generic rating
from "Aa" to "Ba", where 1 is the highest and 3 the lowest ranking within its
generic category. 

Aaa    -- Bonds rated "Aaa" are judged to be of the best quality. They carry the
          smallest degree of investment risk and are generally referred to as
          "gilt edge". Interest payments are protected by a large or by an
          exceptionally stable margin and principal is secure. While the various
          protective elements are likely to change, such changes as can be
          visualized are most unlikely to impair the fundamentally strong
          position of such issues.

Aa     -- Bonds rated "Aa" are judged to be of high quality by all standards.
          Together with the Aaa group they comprise what are generally known as
          high grade bonds. They are rated lower than the best bonds because
          margins of protection may not be as large in Aaa securities or
          fluctuation of protective elements may be of greater amplitude or
          there may be other elements present which make the long-term risks
          appear somewhat larger than in Aaa securities.

A      -- Bonds rated "A" possess many favorable investment attributes and
          are to be considered as upper medium grade obligations. Factors giving
          security to principal and interest are considered adequate but
          elements may be present which suggest a susceptibility to impairment
          some time in the future.

Baa    -- Bonds rated "Baa" are considered as medium grade obligations, i.e.,
          they are neither highly protected nor poorly secured. Interest
          payments and principal security appear adequate for the present but
          certain protective elements may be lacking or may be
          characteristically unreliable over any great length of time. Such
          bonds lack outstanding investment characteristics and in fact have
          speculative characteristics as well.

Ba     -- Bonds rated "Ba" are judged to have speculative elements; their
          future cannot be considered as well-assured. Often the protection of
          interest and principal payments may be very moderate, and therefore
          not well safeguarded during both good and bad times over the future.
          Uncertainty of position characterizes bonds in this class.

Bond Ratings (unaudited)(continued)
================================================================================

Fitch  -- Ratings may be modified by the addition of a plus (+) or minus (-)
          sign to show relative standings within the major rating categories.

A      -- Bonds rated "A" are considered to be investment grade and of high
          credit quality. The obligor's ability to pay interest and/or dividends
          and repay principal is considered to be strong, but may be more
          vulnerable to adverse changes in economic conditions and circumstances
          than securities with higher ratings.

BBB    -- Bonds rated "BBB" are considered to be investment grade and of
          satisfactory credit quality. The obligor's ability to pay interest or
          dividends and repay principal is considered to be adequate. Adverse
          changes in economic conditions and circumstances, however, are more
          likely to have adverse impact on these securities and, therefore,
          impair timely payment. The likelihood that the ratings of these bonds
          will fall below investment grade is higher than for securities with
          higher ratings.

NR     -- Indicates that the bond is not rated by Standard & Poor's, Moody's or
          Fitch.

================================================================================
Short-Team Security Ratings (unaudited)
================================================================================

SP-1   -- Standard & Poor's highest rating indicating very strong or strong
          capacity to pay principal and interest; those issues determined to
          possess overwhelming safety characteristics are denoted with a plus
          (+) sign.
A-1    -- Standard & Poor's highest commercial paper and variable rate demand
          obligation (VRDO) rating indicating that the degree of safety
          regarding timely payment is either overwhelming or very strong; those
          issues determined to possess overwhelming safety characteristics are
          denoted with a plus (+) sign.
VMIG 1 -- Moody's highest rating for issues having a demand feature -- VRDO. 
MIG1   -- Moody's highest rating for short-term municipal obligations. 
P-1    -- Moody'shighest rating for commercial paper and for VRDO prior to the
          advent of the VMIG 1 rating.

1.       Significant Accounting Policies

The Limited Term Portfolio ("Portfolio") is a separate investment portfolio of
the Smith Barney Muni Funds ("Fund"). The Fund, a Massachusetts business trust,
is registered under the Investment Company Act of 1940, as amended, as an open-
end management investment company and consists of this Portfolio and seven other
separate investment portfolios: Florida, Georgia, New York, Pennsylvania,
National, California Money Market and New York Money Market Portfolios. The
financial statements and financial highlights for the other portfolios are
presented in separate semi-annual reports .

The significant accounting policies consistently followed by the Fund are:(a)
security transactions are accounted for on trade date; (b) securities are valued
at the mean between the quoted bid and ask prices provided by an independent
pricing service that are based on transactions in municipal obligations,
quotations from municipal bond dealers, market transactions in comparable
securities and various relationships between securities; (c) securities for
which market quotations are not available will be valued in good faith at fair
market value by or under the direction of the Board of Trustees; (d) securities
maturing within 60 days are valued at cost plus accreted discount or minus
amortized premium, which approximates value; (e) gains or losses on the sale of
securities are calculated by using the specific identification method; (f)
interest income, adjusted for amortization of premium and accretion of original
issue discount, is recorded on an accrual basis; market discount is recognized
upon the disposition of the security; (g) dividends and distributions to
shareholders are recorded on the ex-dividend date; (h) direct expenses are
charged to each Portfolio and each class; management fees and general fund
expenses are allocated on the basis of relative net assets by class; (i) the
Portfolio intends to comply with the applicable provisions of the Internal
Revenue Code of 1986, as amended, pertaining to regulated investment companies
and to make distributions of taxable income sufficient to relieve it from
substantially all Federal income and excise taxes; (j) the character of income
and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles; and
(k) estimates and assumptions are required to be made regarding assets,
liabilities and changes in net assets resulting from operations when financial
statements are prepared. Changes in the economic environment,financial markets
and any other parameters used in determining these estimates could cause actual
results to differ.

2. Exempt-Interest Dividends  and Other Distributions

The Portfolio intends to satisfy conditions that will enable interest from 
municipal securities, which is exempt from regular Federal income tax and from 
designated state income taxes, to retain such tax-exempt status when distributed
to the shareholders of the Portfolio.

Capital gain distributions, if any, are taxable to shareholders, and are 
declared and paid at least annually.

3.  Management Agreement and Transactions with Affiliated Persons

Mutual Management Corp. ("MMC"), a subsidiary of Salomon Smith Barney Holdings
Inc. ("SSBH"), acts as investment manager to the Fund. The Portfolio pays MMC a
management fee calculated at an annual rate of 0.50% of its average daily net
assets. This fee is calculated daily and paid monthly.

On October 8, 1998, CFBDS, Inc. became the Fund's distributor. Prior to that
date Salomon Smith Barney Inc. ("SSB"), was the Fund's distributor. SSB (as well
as certain other broker-dealers) continues to sell Fund shares to the public as
members of the selling group.

On June 12, 1998, the Fund's Class C shares were renamed Class L shares.
Effective June 15, 1998, Class L shares are being sold at net asset value plus a
maximum initial sales charge of 1.00%. Class L shares also have a 1.00%
contingent deferred sales charge ("CDSC"), which applies if redemption occurs
within the first year of purchase.

There is also a CDSC of 1.00% on Class A shares, which applies if redemption
occurs within the first year of purchase. This CDSC only applies to those
purchases of Class A shares, which, when combined with current holdings of Class
A shares, equal or exceed $500,000 in the aggregate. These purchases do not
incur an initial sales charge.

For the six months ended September 30, 1998, SSB received sales charges of
approximately $294,000 and $26,000 on sales of the Portfolios' Class A and Class
L shares, respectively. In addition, for the six months ended September 30,
1998, CDSCs paid to SSB were approximately:

                                                          Class A        Class L
================================================================================
CDSCs                                                     $7,000          $4,000

Pursuant to a Distribution Plan, the Portfolio pays a service fee with respect
to Class A and L shares calculated at an annual rate of 0.15% of the average
daily net assets of each class. In addition, the Portfolio pays a distribution
fee with respect to Class L shares calculated at an annual rate of 0.20% of the
average daily net assets.

For the six months ended September 30, 1998, total Distribution Plan fees
incurred were:


                                                           Class A       Class L

All officers and one Trustee of the Fund are employees of SSB.

4.  Investments

During the six months ended September 30, 1998, the aggregate cost of
purchases and proceeds from sales of investments (including maturities, but
excluding short-term securities) were as follows:

================================================================================
Purchases                                                            $90,043,580

================================================================================

At September 30, 1998, the aggregate gross unrealized appreciation and
depreciation of investments for Federal income tax purposes were substantially
as follows:

================================================================================
Gross unrealized appreciation                                      $ 16,304,929

================================================================================

5.  Capital Loss Carryforward

At March 31, 1998, the Portfolio had, for Federal income tax purposes,
approximately $3,628,000 of capital loss carryforwards available to offset
future capital gains. To the extent that these carryforward losses are used to
offset capital gains, it is possible that the gains so offset will not be
distributed. The amount and expiration of the carryforwards are indicated below.
Expiration occurs on March 31, of the year indicated:

                                                    2003                 2004

6.  Shares of Beneficial Interest

At September 30, 1998, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Portfolio has the
ability to issue multiple classes of shares. Each share of a class represents an

     applicable contingent deferred sales charges ("CDSC") with respect to Class
     B and L shares.
(2)  On June 12, 1998, Class C shares were renamed Class L shares.
(3)  Assumes reinvestment of all dividends and capital gain distributions, if
     any, at net asset value. In addition, Class A and L shares reflect the
     deduction of the maximum initial sales charge of 4.00% and 1.00%,
     respectively. Class B shares reflect the deduction of a 4.50% CDSC, which
     applies if shares are redeemed within one year from purchase. This CDSC
     declines by 0.50% the first year after purchase and thereafter by 1.00% per
     year until no CDSC is incurred. Class L shares also reflect the deduction
     of a 1.00% CDSC, which applies if shares are redeemed also within the first
     year of purchase. All figures represent past performance and are not a
     guarantee of future results. Investment returns and principal value will
     fluctuate, and redemption value may be more or less than the original cost.
+    Total return is not annualized, as it may not be representative of the
     total return for the year.
++   Inception dates for Class A, B and L shares are August 20, 1986, November
     7, 1994 and January 5, 1993, respectively.

================================================================================
FUND HIGHLIGHT
================================================================================

We have continued to maintain a fairly long average life because we believe that
the risk of higher inflation is minimal. As of September 30, 1998, the
call-adjusted average life of the Portfolio was 12.8 years. In addition, we have
placed a greater emphasis on call protection which we believe will provide our
shareholders with more consistent long-term income during the current
low-interest rate environment.

Based on its net asset value ("NAV") of $14.45 as of September 30, 1998 and the
current monthly income distribution per share of $0.064 for Class A shares, this
equates to an annualized distribution rate of 5.31%. For an individual in the
federal income tax bracket of 36%, the Portfolio's tax free yield of 5.31% is
equivalent to a taxable yield of 8.30%. (According to the Internal Revenue
Service, the 36% tax bracket constitutes nearly 10% of all U.S. taxpayers.)

overall for Class A and a four-star rating for Class B and Class L from
Morningstar, Inc.* as of September 30, 1998.

Market and Economic Overview

Bond market performance was shaped primarily by surging demand for U.S. Treasury
securities and a massive issuance of municipal bonds in the past six months.
During the reporting period, municipal bond prices remained relatively flat with
coupon interest providing most of the returns for municipal bonds.

Troubled financial markets abroad and a strengthening U.S. dollar further
exacerbated an already dramatic flight of capital from foreign countries into
U.S. markets. The U.S. Treasury bond, considered to be the global benchmark for
credit quality, was the chief beneficiary of these capital inflows. The large
flows of money into U.S. Treasury securities drove their prices upward and their
yields lower. On September 30, 1998, the yield of the bellwether 30-year U.S.
Treasury bond fell to 4.95%, the lowest level for long-term government debt
since 1967. Since the close of the reporting period, long-term U.S. Treasury
yields fell even further before drifting upward in recent days.

Up until July, many bond investors had been focused on any signs of the
reappearance of inflation. However, developments in the Pacific Rim, such as
Japan's failure to shore up its ailing banking system and Russia's unexpected
devalution of its currency, altered that view considerably. Moreover, a number
of speculators who found themselves caught in highly unusual market conditions
added to the growing uncertainty in U.S. capital markets.

In response to global tumult, the Federal Reserve Board ("Fed") signaled a shift
in policy from vigilance against inflation toward concerns of global deflation
by cutting short-term interest rates 0.25% at its September 1998 meeting. The
rate cut was the first action by the Fed since March 1997.

After the close of the reporting period, the Fed took an extraordinary and
unexpected action of cutting short-term interest rates again by another 0.25% on
October 15, 1998. This latest action brings the federal-funds rate to 5.0% and
the largely symbolic discount rate to 4.75%. (The federal-funds rate is the
interest rate banks charge each other for overnight loans and a closely watched
indicator of the direction of interest rates. The discount rate is the interest
rate the Federal Reserve charges its member banks for loans.)

Foreign investors, who do not benefit from the tax-exempt status of municipal
bonds, have been large buyers of U.S. Treasury securities. As a result, yields
for U.S. Treasury securities have declined further than those of municipal
bonds. Municipal bond yields are currently yielding as much as 100% of
equivalent maturity U.S. Treasury bonds. Municipal bonds are considered by many
investors to be a good value when they yield about 85% of U.S. Treasury bonds.
At their present levels, we believe that tax-exempt bonds can now provide a
competitive income stream for risk-averse investors of almost any income tax
bracket.

In contrast to the diminishing U.S. Treasury security supply, municipal bond
issuance continued at record levels. New issue volume reached its peak in 1993
when $293 billion in new municipal bonds were sold. So far this year, municipal
bond volume is on pace to exceed $300 billion. This disparity in supply and

     Portfolio received 4 stars for the overall, 3-year and 5-year periods. It
     was rated among 1,581 municipal bond funds for the 3-year period, 943

     and 10% receive 1 star. Different classes share a common portfolio of

demand between U.S. Treasury bonds and municipal bonds is a primary reason for
municipal bond underperformance relative to U.S. Treasurys.

Investment Strategy

As previously noted, the Portfolio seeks to provide investors with as high a
level of current income exempt from federal income taxes as is consistent with a
prudent investment approach. The Portfolio has a bias towards good quality,
higher-coupon bonds.

We have continued to maintain a fairly long average life because we believe that
the risk of higher inflation is minimal. As of September 30, 1998, the
call-adjusted average life of the Portfolio was 12.8 years. In addition, we have
placed a greater emphasis on call protection which we believe will provide our
shareholders with more consistent long-term income under the current
low-interest rate environment.

We have also remained committed to higher credit quality. As of September 30,
1998, 94.6% of the Portfolio was rated investment grade or better with roughly
51.2% rated AAA or Aaa, the highest ratings.

During the past six months, we have maintained broad diversification over a
range of different kinds of bonds. In particular, we have emphasized housing and
hospital bonds because we believe that these bonds offer slightly higher yields
than similarly-rated bonds of other categories. As of September 30, 1998, the
Portfolio's assets were concentrated in hospital bonds (15.8%), housing bonds
(14.2%) and education bonds (9.8%).

Municipal Bond Market Outlook

As noted above, we believe that municipal bonds represent excellent values under
the current market conditions. With the stock market's recent volatility, many
investors may be looking to reallocate their existing portfolios. In our
opinion, this may be a timely opportunity for many of these investors to
consider further diversifying their portfolios with municipal bonds.

We believe that economic conditions should remain supportive for the municipal
bond market over the near term. The U.S. economy remains sound despite the
widely reported economic distress of many other countries. Although U.S.
economic growth will likely slow over the coming months, we expect the economy
to expand modestly. Moreover, the Fed should continue to gradually lower
short-term interest rates and that in turn should help correct some of the
imbalances that exist in the overall bond market today.

On a more somber note, we report with much sadness the passing of Emeritus
Director C. Richard Youngdahl. Dick made many valuable contributions to the
Board and the Fund during his tenure and he will be missed.

In closing, we would like to thank you for investing in Smith Barney Muni Funds
- - National Portfolio. We look forward to continuing to help you pursue your
financial goals.

Sincerely,

(1)  Assumes reinvestment of all dividends and capital gain distributions at net
     asset value and does not reflect the deduction of the applicable sales
     charges with respect to Class A and L shares or the applicable contingent
     deferred sales charges ("CDSC") with respect to Class B and L shares.
(2)  Assumes reinvestment of all dividends and capital gain distributions at net
     asset value. In addition, Class A and L shares reflect the deduction of the
     maximum initial sales charge of 4.00% and 1.00%, respectively. Class B
     shares reflect the deduction of a 4.50% CDSC, which applies if shares are
     redeemed within one year from purchase. This CDSC declines by 0.50% the
     first year after purchase and thereafter by 1.00% per year until no CDSC is
     incurred. Class L shares also reflect the deduction of a 1.00% CDSC, which
     applies if shares are redeemed within the first year of purchase.
*    Inception dates for Class A, B and L shares are August 20, 1986, November
     7, 1994 and January 5, 1993, respectively.

</TABLE>


+    Hypothetical illustration of $10,000 invested in Class A shares on
     September 30, 1988, assuming deduction of the maximum 4.00% sales charge at
     the time of investment and reinvestment of dividends (after deduction of
     applicable sales charges through November 6, 1994, and thereafter at net
     asset value) and capital gains (at net asset value) through September 30,
     1998. The performance of the Portfolio's other classes may be greater or
     less than the Class A shares' performance indicated on this chart,
     depending on whether greater or lesser sales charges and fees were incurred
     by shareholders investing in the other classes.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption values may be more or less than the original cost. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

++   It is the opinion of management that the Lehman Brothers Municipal Bond
     Index is a more appropriate broad-based benchmark for the market in which
     the National Portfolio invests, rather than the Lehman Brothers Municipal
     Long Bond Index. In future reporting, the Lehman Brothers Municipal Bond
     Index will be used as a basis of comparison of total return performance
     rather than the Lehman Brothers Municipal Long Bond Index. The Lehman
     Brothers Municipal Long Bond Index (consisting of maturities of at least 22
     years) is a sub-index of the Lehman Brothers Municipal Bond Index, a
     broad-based, total return index comprised of investment grade, fixed rate
     municipal bonds selected from issues larger than $50 million issued January
     1991. Each index is unmanaged and is not subject to the same management and
     trading expenses as a mutual fund.

================================================================================
Bond Ratings (unaudited)
================================================================================

All ratings are by Standard & Poor's Ratings Service ("Standard & Poor's"),
except those identified by an asterisk (*) are rated by Moody's Investors
Service Inc. ("Moody's"). The definitions of the applicable rating symbols are
set forth below:

Standard & Poor's -- Ratings from "AA" to "B" may be modified by the addition of
a plus (+) or minus (-) sign to show relative standings within the major rating
categories.

AAA              -- Bonds rated "AAA" have the highest rating assigned by
                    Standard & Poor's to a debt obligation. Capacity to pay
                    interest and repay principal is extremely strong.

AA               -- Bonds rated "AA" have a very strong capacity to pay interest
                    and repay principal and differ from the highest rated issues
                    only in a small degree.

A                -- Bonds rated "A" have a strong capacity to pay interest and
                    repay principal although they are somewhat more susceptible
                    to the adverse effects of changes in circumstances and
                    economic conditions than debt in higher rated categories.

BBB              -- Bonds rated "BBB" are regarded as having an adequate
                    capacity to pay interest and repay principal. Whereas they
                    normally exhibit adequate protection parameters, adverse
                    economic conditions or changing circumstances are more
                    likely to lead to a weakened capacity to pay interest and
                    repay principal for bonds in this category than for bonds in
                    higher rated categories.

BB and B         -- Bonds rated BB and B are regarded, on balance, as
                    predominantly speculative with respect to the issuer's
                    capacity to pay interest and repay principal in accordance
                    with the terms of the obligation. BB indicates the lowest
                    degree of speculation and B the highest degree of
                    speculation. While such bonds will likely have some quality
                    and protective characteristics, these are outweighed by
                    large uncertainties or major risk exposures to adverse
                    conditions.

Moody's -- Numerical modifiers 1, 2 and 3 may be applied to each generic rating
from "Aa" to "Baa," where 1 is the highest and 3 the lowest ranking within its
generic category.

Aaa              -- Bonds rated "Aaa" are judged to be of the best quality. They
                    carry the smallest degree of investment risk and are
                    generally referred to as "gilt edge." Interest payments are
                    protected by a large or by an exceptionally stable margin
                    and principal is secure. While the various protective
                    elements are likely to change, such changes as can be
                    visualized are most unlikely to impair the fundamentally
                    strong position of such issues.

Aa               -- Bonds rated "Aa" are judged to be of high quality by all
                    standards. Together with the "Aaa" group they comprise what
                    are generally known as high grade bonds. They are rated
                    lower than the best bonds because margins of protection may
                    not be as large in "Aaa" securities or fluctuation of
                    protective elements may be of greater amplitude or there may
                    be other elements present which make the long-term risks
                    appear somewhat larger than in "Aaa" securities.

A                -- Bonds rated "A" possess many favorable investment attributes
                    and are to be considered as upper medium grade obligations.
                    Factors giving security to principal and interest are
                    considered adequate but elements may be present which
                    suggest a susceptibility to impairment some time in the
                    future.

Baa              -- Bonds rated "Baa" are considered to be medium grade
                    obligations, i.e., they are neither highly protected nor
                    poorly secured. Interest payments and principal security
                    appear adequate for the present but certain protective
                    elements may be lacking or may be characteristically
                    unreliable over any great length of time. Such bonds lack
                    outstanding investment characteristics and in fact have
                    speculative characteristics as well.

NR               -- Indicates that the bond is not rated by either Standard &
                    Poor's or Moody's.

Short-Term Securities Ratings (unaudited)
================================================================================
  
SP-1             -- Standard & Poor's highest rating indicating very strong or
                    strong capacity to pay principal and interest; those issues
                    determined to possess overwhelming safety characteristics
                    are denoted with a plus (+) sign.

A-1              -- Standard & Poor's highest commercial paper and variable-rate
                    demand obligation (VRDO) rating indicating that the degree
                    of safety regarding timely payment is either overwhelming or
                    very strong; those issues determined to possess overwhelming
                    safety characteristics are denoted with a plus (+) sign.

VMIG 1           -- Moody's highest rating for issues having a demand feature --
                    VRDO.

P-1              -- Moody's highest rating for commercial paper and for VRDO
                    prior to the advent of the VMIG 1 rating.

1.   Significant Accounting Policies

The National Portfolio ("Portfolio") is a separate investment portfolio of the
Smith Barney Muni Funds ("Fund"). The Fund, a Massachusetts business trust, is
registered under the Investment Company Act of 1940, as amended, as an open-end
management investment company and consists of this Portfolio and seven other
separate investment portfolios: Florida, Georgia, Limited Term, New York,
Pennsylvania, California Money Market and New York Money Market Portfolios. The
financial statements and financial highlights for the other portfolios are
presented in separate semi-annual reports.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities are valued
at the mean between the bid and ask prices provided by an independent pricing
service which are based on transactions in municipal obligations, quotations
from municipal bond dealers, market transactions in comparable securities and
various relationships between securities; (c) securities for which market
quotations are not available will be valued in good faith at fair value by or
under the direction of the Board of Trustees; (d) securities maturing within 60
days are valued at cost plus accreted discount or minus amortized premium, if
any, which approximates value; (e) gains or losses on the sale of securities are
calculated by using the specific identification method; (f) interest income,
adjusted for amortization of premium and accretion of original issue discount,
is recorded on an accrual basis; market discount is recognized upon the
disposition of the security; (g) dividends and distributions to shareholders are
recorded on the ex-dividend date; (h) direct expenses are charged to each
Portfolio and each class; management fees and general fund expenses are
allocated on the basis of relative net assets by class; (i) the character of
income and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles; (j)
the Portfolio intends to comply with the applicable provisions of the Internal
Revenue Code of 1986, as amended, pertaining to regulated investment companies
and to make distributions of taxable income sufficient to relieve it from
substantially all Federal income and excise taxes; and (k) estimates and
assumptions are required to be made regarding assets, liabilities and changes in
net assets resulting from operations when financial statements are prepared.
Changes in the economic environment, financial markets and any other parameters
used in determining these estimates could cause actual results to differ.

2.   Exempt-Interest Dividends and Other Distributions

The Portfolio intends to satisfy conditions that will enable interest from
municipal securities, which is exempt from regular Federal income tax and from
designated state income taxes, to retain such tax-exempt status when distributed
to the shareholders of the Portfolio.

Capital gains distributions, if any, are taxable to shareholders, and are
declared and paid at least annually.

3.   Management Agreement and Other Transactions

Mutual Management Corp. ("MMC"), a subsidiary of Salomon Smith Barney Holdings
Inc. ("SSBH"), acts as investment manager to the Fund. The Portfolio pays MMC a
management fee calculated at the annual rate of 0.45% of the average daily net
assets. This fee is calculated daily and paid monthly.

On October 8, 1998, CFBDS, Inc. became the Fund's distributor. Prior to that
date, Salomon Smith Barney Inc ("SSB"), another subsidary of SSBH, was the
Fund's distributor. SSB (as well as certain other broker-dealers) continues to
sell Fund shares to the public as a member of the selling group.

On June 12, 1998, the Fund's existing Class C shares were renamed Class L
shares. Effective June 15, 1998, Class L shares are being sold at net asset
value plus a maximum initial sales charge of 1.00%. Class L shares

also have a 1.00% contingent deferred sales charge ("CDSC"), which applies if
redemption occurs within the first year of purchase.

There is also a CDSC of 4.50% on Class B shares, which applies if redemption
occurs within one year from purchase. This CDSC declines by 0.50% the first year
after purchase and thereafter by 1.00% per year until no CDSC is incurred. For
the six months ended September 30, 1998, SSB received sales charges of $336,000
and $18,000 on sales of the Fund's Class A and L shares, respectively. In
addition, CDSCs paid to SSB were approximately $13,000 for Class B shares.

Pursuant to a Distribution Plan, the Portfolio pays a service fee with respect
to Class A, B and L shares calculated at the annual rate of 0.15% of the average
daily net assets of each respective class. In addition, the Portfolio pays a
distribution fee with respect to Class B and L shares calculated at the annual
rates of 0.50% and 0.55% of the average daily net assets of each class,
respectively. For the six months ended September 30, 1998, total Distribution
Plan fees incurred were:

5.   Transfer of Net Assets

On December 5, 1997, the National Portfolio acquired the assets and certain
liabilities of the Smith Barney Muni Funds -- Ohio Portfolio ("Ohio Portfolio")
pursuant to a plan of reorganization approved by Ohio Portfolio shareholders on
November 21, 1997. Total shares issued by the National Portfolio and the total
net assets of the Ohio Portfolio and the National Portfolio on the date of the
transfer were as follows:

================================================================================
</TABLE>

The total net assets of the Ohio Portfolio before acquisition included
unrealized appreciation of $525,586. Total net assets of the National Portfolio
immediately after the transfer were $394,888,114. The transaction was structured
to qualify as a tax-free reorganization under the Internal Revenue Code of 1986,
as amended.

6.   Shares of Beneficial Interest

At September 30, 1998, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Portfolio has the
ability to issue multiple classes of shares. Each share of a class represents an
identical interest in the Portfolio and has the same rights, except that each
class bears certain expenses specifically related to the distribution of its
shares. Effective June 12, 1998, the Fund adopted the renaming of existing Class
C shares as Class L shares.

At September 30, 1998, total paid-in capital amounted to the following for each
class:

Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Muni Funds
- - Florida Portfolio ("Portfolio") for the period ended September 30, 1998. For
your convenience, we have summarized the period's prevailing economic and market
conditions below and outlined the various investment strategies employed by the
Fund during the period under review. A detailed summary of performance and
current holdings for the Fund can be found in the appropriate sections that
follow.

Fund's Performance and Investment Strategy

For the six months ended September 30, 1998, the Florida Portfolio generated a
total return of 4.61% for Class A shares which compares favorably with its
Lipper Analytical Services, Inc. peer group average of 4.30% (Lipper is a major
fund-tracking organization.) For performance information on the Portfolio's
other share classes, please see pages 5 and 6.

We are pleased to report that your Portfolio has been given a four-star rating
overall for its Class A, Class B and Class L shares from Morningstar, Inc.* as
of September 30, 1998.

Given present market conditions, we have continued to emphasize credit quality
and call protection in the Portfolio. As of the close of the reporting period,
93.2% of the Portfolio's bond holdings was rated investment grade or better and
the Portfolio's average stated call protection was 8.9 years. The Portfolio's
holdings were concentrated among the following industries: housing bonds
(17.8%), transportation bonds (15.3%), hospital bonds (9.7%) and utility bonds
(8.7%).

Market and Economic Overview

Bond market performance was shaped primarily by surging demand for U.S. Treasury
securities and a massive issuance of municipal bonds in the past six months.
During the reporting period, municipal bond prices remained relatively flat with
coupon interest providing most of the returns for municipal bonds.

Troubled financial markets abroad and a strengthening U.S. dollar further
exacerbated an already dramatic flight of capital from foreign countries into
U.S. markets. The U.S. Treasury bond, considered to be the global benchmark for
credit quality, was the chief beneficiary of these capital inflows. The large
flows of money into U.S. Treasury securities drove their prices upward and their
yields lower. On September 30, 1998, the yield of the bellwether 30-year U.S.
Treasury bond fell to 4.95%, the lowest level for long-term government debt
since 1967. Since the close of the reporting period, long-term U.S. Treasury
yields fell even further before drifting upward in recent days.

Until July, many bond investors had been primarily concerned about whether there
were any signs of the reappearance of inflation. However, developments in the
Pacific Rim, such as Japan's failure to shore up its ailing banking system and
Russia's unexpected devaluation of its currency, altered that focus
considerably. Moreover, a number of speculators who found themselves caught in
highly unusual market conditions added to the growing uncertainty in U.S.
capital markets.

In response to foreign economic conditions, the Federal Reserve Board ("Fed")
signaled a shift in policy from vigilance against inflation toward concerns of
global deflation by cutting short-term interest rates by 0.25% at its September
1998 meeting. The rate cut was the first action by the Fed since March 1997.

After the close of the reporting period, the Fed took an extraordinary and
unexpected action of cutting short-term interest rates again by another 0.25% on
October 15, 1998. This latest action brings the federal funds rate to 5.0% and
the largely symbolic discount rate to 4.75%. (The federal funds rate is the
interest rate banks charge each other for overnight loans and a closely watched
indicator of the direction of interest rates. The discount rate is the interest
rate the Federal Reserve charges its member banks for loans.)

Foreign investors, who do not benefit from the tax-exempt status of municipal
bonds, have been large buyers of U.S. Treasury securities. As a result, yields
for U.S. Treasury securities have declined further than those of municipal
bonds. Some municipal bonds are currently yielding as much as 100% of equivalent
maturity U.S. Treasury bonds. Municipal bonds are considered by many investors
to be a good value when they yield at least 85% of U.S.

Treasury bonds. At their present levels, we believe that tax-exempt bonds can
provide a competitive income stream for investors of almost any income tax
bracket.

In contrast to the diminishing U.S. Treasury security supply, municipal bond
issuance continued at record levels. New issue volume reached its peak in 1993
when $293 billion in new municipal bonds were sold. So far this year, municipal
bond volume is on pace to exceed $300 billion. This disparity in supply and
demand between U.S. Treasury bonds and municipal bonds is a primary reason for
municipal bond underperformance relative to U.S. Treasurys.

Florida Economic Highlights

Florida continues to experience rapid economic and population growth as it
proceeds with its transformation to an even more diversified economy. The
Sunshine State has made significant progress in transforming its economy from a
seasonal base of agriculture and tourism to more of a service and trade economy.
Moreover, financial service companies such as banks and insurance companies have
played an increasingly important role in the greater diversification of
Florida's economy. This rapid growth has added to the growing need for
additional infrastructure and educational facilities. The State has been
successful in maintaining moderate debt levels despite the increase in demand
for municipal spending. However, Florida's overdependence on sales tax revenues
could make it more vulnerable in the event of an economic downturn.

Municipal Bond Market Outlook

In view of the above, we believe that municipal bonds represent excellent values
under the current market conditions. With the stock market's recent volatility,
many investors may be looking to reallocate a portion of their existing
portfolios away from equities. In our opinion, this may be a timely opportunity
for many of these investors to do so with investments in municipal bonds.

We believe that economic conditions should remain supportive for the municipal
bond market over the near term. The U.S. economy remains sound despite the
widely reported economic distress of many other countries. Although U.S.
economic growth will likely slow over the coming months, we expect the economy
to expand modestly. Moreover, the Fed should continue to gradually lower
short-term interest rates and that in turn should help correct some of the
imbalances that exist in the overall bond market today.

On a more somber note, we report with much sadness the passing of Emeritus
Trustee C. Richard Youngdahl. Dick made many valuable contributions to the Board
and the Fund during his tenure and he will be missed.

Thank you for investing in the Smith Barney Muni Funds - Florida Portfolio. We
look forward to helping you pursue your investment goals in the years ahead.

(1)   Assumes reinvestment of all dividends and capital gain distributions, if
      any, at net asset value and does not reflect the deduction of the
      applicable sales charges with respect to Class A and L shares or the
      applicable contingent deferred sales charges ("CDSC") with respect to
      Class B and L shares.

(2)   On June 12, 1998, Class C shares were renamed Class L shares.

(3)   Assumes reinvestment of all dividends and capital gain distributions, if
      any, at net asset value. In addition, Class A and L shares reflect the
      deduction of the maximum initial sales charge of 4.00% and 1.00%,
      respectively; and Class B shares reflect the deduction of a 4.50% CDSC,
      which applies if shares are redeemed within one year from purchase. This
      CDSC declines by 0.50% the first year after purchase and thereafter by
      1.00% per year until no CDSC is incurred. Class L shares reflect the
      deduction of a 1.00% CDSC, which applies if shares are redeemed within the
      first year of purchase.

*     Inception dates for Class A, B and L shares are April 2, 1991, November
      16, 1994 and january 5, 1993, respectively.

+     Total return is not annualized, as it may not be representative of the
      total return for the year.

+     Hypothetical illustration of $10,000 invested in Class A shares at
      inception on April 2, 1991, assuming deduction of the maximum 4.00% sales
      charge at the time of investment and reinvestment of dividends (after
      deduction of applicable sales charges through November 6, 1994, and
      thereafter at net asset value) and capital gains, if any, at net asset
      value through September 30, 1998. The performance of the Portfolio's other
      classes may be greater or less than the Class A shares' performance
      indicated on this chart, depending on whether greater or lesser sales
      charges and fees were incurred by shareholders investing in the other
      classes.

      All figures represent past performance and are not a guarantee of future
      results. Investment returns and principal value will fluctuate, and
      redemption values may be more or less than the original cost. No
      adjustment has been made for shareholder tax liability on dividends or
      capital gains.

*     It is the opinion of management that the Lehman Brothers Municipal Bond
      Index is a more appropriate broad-based benchmark for the market in which
      the Florida Portfolio invests rather than the Lehman Brothers Municipal
      Long Bond Index. In future reporting, the Lehman Brothers Municipal Bond
      Index will be used as a basis of comparison of total return performance
      rather than the Lehman Brothers Municipal Long Bond Index. The Lehman
      Brothers Municipal Long Bond Index (consisting of maturities of at least
      22 years) is a sub-index of the Lehman Brothers Municipal Bond Index, a
      broad-based, total return index comprised of investment grade, fixed rate
      municipal bonds selected from issues larger than $50 million issued since
      January 1991. Each index is unmanaged and is not subject to the same
      management and trading expenses of a mutual fund.

AAA      -- Bonds rated "AAA" have the highest rating assigned by Standard &
            Poor's. Capacity to pay interest and repay principal is extremely
            strong.

AA       -- Bonds rated "AA" have a very strong capacity to pay interest and
            repay principal and differ from the highest rated issues only in a
            small degree.

A        -- Bonds rated "A" have a strong capacity to pay interest and repay
            principal although they are somewhat more susceptible to the adverse
            effects of changes in circumstances and economic conditions than
            bonds in higher rated categories.

BBB      -- Bonds rated "BBB" are regarded as having an adequate capacity to pay
            interest and repay principal. Whereas they normally exhibit adequate
            protection parameters, adverse economic conditions or changing
            circumstances are more likely to lead to a weakened capacity to pay
            interest and repay principal for bonds in this category than in
            higher rated categories.

BB       -- Bonds rated "BB" have less near-term vulnerability to default than
            other speculative issues. However, it faces major ongoing
            uncertainties or exposure to adverse business, financial, or
            economic conditions which could lead to inadequate capacity to meet
            timely interest and principal payments.

Moody's -- Numerical modifiers 1, 2, and 3 may be applied to each generic rating
from "Aa" to "Baa", where 1 is the highest and 3 the lowest rating within its
generic category.

Aaa      -- Bonds rated "Aaa" are judged to be of the best quality. They carry
            the smallest degree of investment risk and are generally referred to
            as "gilt edge." Interest payments are protected by a large or by an
            exceptionally stable margin and principal is secure. While the
            various protective elements are likely to change, such changes as
            can be visualized are most unlikely to impair the fundamentally
            strong position of such issues.

Aa       -- Bonds rated "Aa" are judged to be of high quality by all standards.
            Together with the "Aaa" group they comprise what are generally known
            as high grade bonds. They are rated lower than the best bonds
            because margins of protection may not be as large as in "Aaa"
            securities or fluctuation of protective elements may be of greater
            amplitude or there may be other elements present which make the
            long-term risks appear somewhat larger than in "Aaa" securities.

A        -- Bonds rated "A" possess many favorable investment attributes and are
            to be considered as upper medium grade obligations. Factors giving
            security to principal and interest are considered adequate but
            elements may be present which suggest a susceptibility to impairment
            some time in the future.

Baa      -- Bonds rated "Baa" are considered as medium grade obligations, i.e.,
            they are neither highly protected nor poorly secured. Interest
            payments and principal security appear adequate for the present but
            certain protective elements may be lacking or may be
            characteristically unreliable over any great length of time. Such
            bonds lack outstanding investment characteristics and in fact have
            speculative characteristics as well.

Bond Ratings (unaudited) (continued)
- --------------------------------------------------------------------------------

Fitch -- Ratings may be modified by the addition of a plus (+) sign or minus (-)
sign to show relative standings within the major ratings categories.

AA       -- Bonds rated "AA" are considered to be investment grade and of very
            high credit quality. The obligor's ability to pay interest and/or
            dividends and repay principal is very strong.

BBB      -- Bonds rated "BBB" are considered to be investment grade and of
            satisfactory credit quality. The obligor's ability to pay interest
            or dividends and repay principal is considered to be adequate.
            Adverse changes in economic conditions and circumstances, however,
            are more likely to have adverse impact on these securities and,
            therefore, impair timely payment. The likelihood that the ratings of
            these bonds will fall below investment grade is higher than for
            securities with higher ratings.

NR       -- Indicates that the bond is not rated by Standard & Poor's, Moody's
            or Fitch.

Short-Term Security Ratings (unaudited)
- --------------------------------------------------------------------------------

SP-1     -- Standard & Poor's highest rating indicating very strong or strong
            capacity to pay principal and interest; those issues determined to
            possess overwhelming safety characteristics are denoted with a plus
            (+) sign.

A-1      -- Standard & Poor's highest commercial paper and variable rate demand
            obligation (VRDO) rating indicating that the degree of safety
            regarding timely payment is either overwhelming or very strong;
            those issues determined to possess overwhelming safety
            characteristics are denoted with a (+) sign.

VMIG 1   -- Moody's highest rating for issues having demand feature -- VRDO.

P-1      -- Moody's highest rating for commercial paper and for VRDO prior to
            the advent of the VMIG 1 rating.

1. Significant Accounting Policies

The Florida Portfolio ("Portfolio") is a separate investment portfolio of the
Smith Barney Muni Funds ("Fund"). The Fund, a Massachusetts business trust, is
registered under the Investment Company Act of 1940, as amended, as an open-end
management investment company. The Fund consists of this Portfolio and seven
other separate investment portfolios: Georgia, Limited Term, National, New York,
Pennsylvania, New York Money Market and California Money Market Portfolios. The
financial statements and financial highlights for the other portfolios are
presented in separate semi-annual reports.

The significant accounting policies consistently followed by the Portfolio are:
(a) security transactions are accounted for on trade date; (b) securities are
valued at the mean between the quoted bid and ask prices provided by an
independent pricing service that are based on transactions in municipal
obligations, quotations from municipal bond dealers, market transactions in
comparable securities and various relationships between securities; (c)
securities for which market quotation are not available in good faith at fair
market value by or under the direction of the Board of Trustees; (d) securities
maturing within 60 days are valued at cost plus accreted discount or minus
amortized premium, which approximates value; (e) gains or losses on the sale of
securities are calculated by using the specific identification method; (f)
interest income, adjusted for amortization of premium and accretion of original
issue discount, is recorded on an accrual basis; market discount is recognized
upon the disposition of the security; (g) direct expenses are charged to each
class; management fees and general fund expenses are allocated on the basis of
relative net assets; (h) dividends and distributions to shareholders are
recorded on the ex-dividend date; (i) the Portfolio intends to comply with the
applicable provisions of the Internal Revenue Code of 1986, as amended,
pertaining to regulated investment companies and to make distributions of
taxable income sufficient to relieve it from substantially all Federal income
and excise taxes; (j) the character of income and gains to be distributed are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles. At March 31, 1998, reclassifications
were made to the Portfolio's capital accounts to reflect permanent book/tax
differences and income and gains available for distributions under income tax
regulations. Net investment income, net realized gains and net assets were not
affected by this adjustment; and (k) estimates and assumptions are required to
be made regarding assets, liabilities and changes in net assets resulting from
operations when financial statements are prepared. Changes in the economic
environment, financial markets and any other parameters used in determining
these estimates could cause actual results to differ.

2. Portfolio Concentration

Since the Portfolio invests primarily in obligations of issuers within Florida,
it is subject to possible concentration risks associated with economic,
political, or legal developments or industrial or regional matters specifically
affecting Florida.

3. Exempt-Interest Dividends and Other Distributions

The Portfolio intends to satisfy conditions that will enable interest from
municipal securities, which is exempt from regular Federal income tax and from
designated state income taxes, to retain such tax-exempt status when distributed
to the shareholders of the Portfolio.

Capital gain distributions, if any, are taxable to shareholders, and are
declared and paid at least annually.

4. Management Agreement and Other Transactions

Mutual Management Corp. ("MMC"), a subsidiary of Salomon Smith Barney Holdings
Inc. ("SSBH"), acts as investment manager to the Fund. The Portfolio pays MMC a
management fee calculated at an annual rate of 0.50% of its average daily net
assets. This fee is calculated daily and paid monthly.

On October 8, 1998, CFBDS, Inc. became the Fund's distributor. Prior to that
date, Salomon Smith Barney Inc. ("SSB") was the Fund's distributor. SSB (as well
as certain other broker-dealers) continues to sell Fund shares to the public as
members of the selling group.

On June 12, 1998, the Fund's Class C shares were renamed Class L shares.
Effective June 15, 1998, Class L shares are being sold at net asset value plus
an initial sales charge of 1.00%. Class L shares also have a 1.00% contingent
deferred sales charge ("CDSC"), which applies if redemption occurs within the
first year of purchase.

There is a CDSC of 4.50% on Class B shares, which applies if redemption occurs
within one year from purchase. This CDSC declines by 0.50% the first year after
purchase and thereafter by 1.00% per year until no CDSC is incurred. In
addition, Class A shares also have a 1.00% CDSC, which applies if redemption
occurs within the first year of purchase. This CDSC only applies to those
purchases of Class A shares, which, when combined with current holdings of Class
A shares, equal or exceed $500,000 in the aggregate. These purchases do not
incur an initial sales charge.

daily net assets for each respective class. The Portfolio pays a distribution
fee with respect to Class B and L shares calculated at the annual rates of 0.50%
and 0.55% of the average daily net assets of those classes, respectively. For

6. Shares of Beneficial Interest

At September 30, 1998, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Portfolio has the
ability to issue multiple classes of shares. Each share of a class represents an
identical interest in the Portfolio and has the same rights, except that each
class bears certain expenses related to the distribution of its shares.

At September 30, 1998, total paid-in capital amounted to the following for each
class:

                                     Class A           Class B         Class L

Dear Shareholder:

We are pleased to provide the semi-annual report for the Smith Barney Muni Funds
- - Georgia and Pennsylvania Portfolios ("Portfolio") for the period ended
September 30, 1998. For your convenience, we have summarized the period's
prevailing economic and market conditions below and outlined the investment
strategies employed by each Portfolio during the period. A detailed summary of
performance and current holdings for both Portfolios can be found in the
appropriate sections that follow.

Market and Economic Overview

Bond market performance was shaped primarily by surging demand for U.S. Treasury
securities and a massive issuance of municipal bonds in the past six months.
During the reporting period, municipal bond prices remained relatively flat with
coupon interest providing most of the returns for municipal bonds.

Troubled financial markets abroad and a strengthening U.S. dollar further
exacerbated an already dramatic flight of capital from foreign countries into
U.S. markets. The U.S. Treasury bond, considered to be the global benchmark for
credit quality, was the chief beneficiary of these capital inflows. The large
flows of money into U.S. Treasury securities drove their prices upward and their
yields lower. On September 30, 1998, the yield of the bellwether 30-year U.S.
Treasury bond fell to 4.95%, the lowest level for long-term government debt
since 1967. Since the close of the reporting period, long-term U.S. Treasury
yields fell even further before drifting upward in recent days.

Up until July, many bond investors had been focused on any signs of the
reappearance of inflation. However, developments in the Pacific Rim, such as
Japan's failure to shore up its ailing banking system and Russia's unexpected
devaluation of its currency, altered that view considerably. Moreover, a number
of speculators who found themselves caught in highly unusual market conditions
added to the growing uncertainty in U.S. capital markets.

<PAGE>

In response to the global tumult, the Federal Reserve Board ("Fed") signaled a
shift in policy from vigilance against inflation toward concerns of global
deflation by cutting short-term interest rates 0.25% at its September 1998
meeting. The rate cut was the first action by the Fed since March 1997.

After the close of the reporting period, the Fed took an extraordinary and
unexpected action of cutting short-term interest rates again by another 0.25% on
October 15, 1998. This latest action brings the federal-funds rate to 5.00% and
the largely symbolic discount rate to 4.75%. (The federal-funds rate is the
interest rate banks charge each other for overnight loans and a closely watched
indicator of the direction of interest rates. The discount rate is the interest
rate the Federal Reserve charges its member banks for loans.)

Foreign investors, who do not benefit from the tax-exempt status of municipal
bonds, have been large buyers of U.S. Treasury securities. As a result, yields
for U.S. Treasury securities have declined further than those of municipal
bonds. Municipal bond yields are currently yielding as much as 100% of
equivalent maturity U.S. Treasury bonds. Municipal bonds are considered by many
investors to be a good value when they yield about 85% of U.S. Treasury bonds.
At their present levels, we believe that tax-exempt bonds can now provide a
competitive income stream for risk-averse investors of almost any income tax
bracket.

In contrast to the diminishing U.S. Treasury security supply, municipal bond
issuance continued at record levels. New issue volume reached its peak in 1993
when $293 billion in new municipal bonds were sold. So far this year, municipal
bond volume is on pace to exceed $300 billion. This disparity in supply and
demand between U.S. Treasury bonds and municipal bonds is a primary reason for
municipal bond underperformance relative to U.S. Treasurys.

Georgia Portfolio's Performance and Investment Strategy

For the six months ended September 30, 1998, the Georgia Portfolio generated a
total return of 5.21% for Class A shares and significantly outperformed its
Lipper Analytical Services, Inc. peer group average of 4.52%. (Lipper is a major
fund tracking organization.)

In view of current market conditions, we have maintained a fairly long average
life of our holdings and continued to place emphasis on call protection and
credit quality. As of September 30, 1998, the call-adjusted average life was
14.6 years and 95.2% of the Portfolio was rated investment grade. In addition,
approximately 53.0% of the Portfolio had a triple-A rating, the highest credit
rating. The Portfolio's largest holdings are concentrated in housing bonds
(21.0%), water and sewer bonds (15.6%) and utility bonds (11.4%).

We are pleased to report that your Portfolio has been given a four-star rating
overall for Class A and B and Class L from Morningstar, Inc.* as of September
30, 1998.

Georgia Economic Highlights

Our outlook for Georgia's economy remains very bright. The Peach State continues
to earn high marks from major credit rating agencies due in large part to its
prudent debt management and conservative fiscal policies. Moreover, a booming
economy in Georgia has led to increased tax revenues and solid gains in
employment. Compared to its previous fiscal year, personal income tax revenues
grew by 14.8% and corporate income taxes rose substantially. Like many other
states, job growth in Georgia has been concentrated mainly in the service
industries.

By many accounts, Georgia has been highly successful in attracting new
entrepreneurship. According to Georgia Secretary of State Lewis Massey,
corporate activity had increased by more than 10% by the end of 1997. In
addition, the State has also demonstrated that it can compete aggressively in
world export markets. Despite economic woes in many parts of the world,
Georgia's exports grew by more than 3% overall in the first half of 1998 over
the same period in 1997. Exports to major U.S. trading partners such as Canada
and Mexico grew respectably while market share in strategic European Union
nations such as France and Spain increased substantially. In our view, Georgia
is well positioned to take advantage of current economic globalization trends.

Pennsylvania Portfolio's Performance and Investment Strategy

For the six months ended September 30, 1998, the Pennsylvania Portfolio posted a
total return of 4.83% for Class A shares and significantly outperformed its
Lipper peer group average of 3.91%.

We have continued to lengthen the Portfolio's maturity structure and have
extended the call-adjusted average life of the Portfolio from 12.8 years on
March 31, 1998 to 13.2 years. Average stated call protection was also extended
from 9.3 years to 9.8 years. The emphasis on longer maturities and call
protection is designed to help preserve a competitive stream of income over the
long term in a low-interest rate environment.

(8.8%).

We are pleased to report that the Portfolio has been given a four-star rating
overall for Class A and B and Class L from Morningstar, Inc.** as of September
30, 1998.

Pennsylvania Economic Highlights

Pennsylvania continues to make great strides in reforming its economy and
rehabilitating its image as a former rustbelt state. Only three years ago,
annual job growth in the Commonwealth was ranked 45th in the nation. Today,
annual job growth stands at 17th thanks in large part to the development of high
technology and advanced manufacturing businesses. In recognition of these
positive changes, the July 27, 1998 edition of Business Week cited Pennsylvania
as one of its Top Ten in its economic development report card.

A vibrant economy, fiscal restraint and effective debt management has enabled
the Commonwealth to accumulate reserves even while lowering taxes for
individuals and businesses. In our opinion, Pennsylvania is well-positioned for
continued economic growth for the foreseeable future.

National Outlook

As noted earlier, we believe that municipal bonds represent excellent values
under the current market conditions. With the stock market's recent volatility,
many investors may be looking to reallocate their existing portfolios. In our
opinion, this may be a timely opportunity for many of these investors to
consider further diversifying their portfolios with municipal bonds.

We believe that economic conditions should remain supportive for the municipal
bond market over the near term. The U.S. economy remains sound despite the
widely reported economic distress of many other countries. Although U.S.
economic growth will likely slow over the coming months, we expect the economy
to expand modestly. Moreover, the Fed should continue to gradually lower
short-term interest rates and that in turn should help correct some of the
imbalances that exist in the overall bond market today.

(3)   Assumes reinvestment of all dividends and capital gain distributions, if
      any, at net asset value. In addition, Class A and L shares reflect the
      deduction of the maximum sales charge of 4.00% and 1.00%, respectively;
      Class B shares reflect the deduction of a 4.50% CDSC, which applies if
      shares are redeemed within one year from initial purchase. This CDSC
      declines by 0.50% the first year after purchase and thereafter by 1.00%
      per year until no CDSC is incurred. Class L shares also reflect the
      deduction of a 1.00% CDSC, which applies if shares are redeemed within the
      first year of purchase.

*     Inception dates for Class A, B and L shares are April 4, 1994, June 15,
      1994 and April 14, 1994, respectively.

+     Hypothetical illustration of $10,000 invested in Class A shares at
      inception on April 4, 1994, assuming deduction of the maximum 4.00% sales
      charge at the time of investment and reinvestment of dividends and capital
      gains, if any, at net asset value through September 30, 1998. The
      performance of the Portfolio's other classes may be greater or less than
      the Class A shares' performance indicated on this chart, depending on
      whether greater or lesser sales charges and fees were incurred by
      shareholders investing in the other classes.

      All figures represent past performance and are not a guarantee of future
      results. Investment returns and principal value will fluctuate, and
      redemption values may be more or less than the original cost. No
      adjustment has been made for shareholder tax liability on dividends or
      capital gains.

*     It is the opinion of management that the Lehman Brothers Municipal Bond
      Index is a more appropriate broad-based benchmark for the market in which
      the Georgia Portfolio invests rather than the Lehman Brothers Municipal
      Long Bond Index. In future reporting, the Lehman Brothers Municipal Bond
      Index and the Lehman Brothers Georgia Municipal Bond Index will be used as
      a basis of comparison of total return performance rather than the Lehman
      Brothers Municipal Long Bond Index. The Lehman Brothers Municipal Long
      Bond Index (consisting of maturities of at least 22 years) and the Lehman
      Brothers Georgia Municipal Bond Index (consisting of Georgia municipal
      bonds) are each a sub-index of the Lehman Brothers Municipal Bond Index, a
      broad-based, total return index comprised of investment grade, fixed rate
      municipal bonds selected from issues larger than $50 million issued since
      January 1991. Each index is unmanaged and is not subject to the same
      management and trading expenses of a mutual fund.

      All figures represent past performance and are not a guarantee of future
      results. Investment returns and principal value will fluctuate, and
      redemption values may be more or less than the original cost. No
      adjustment has been made for shareholder tax liability on dividends or
      capital gains.

*     It is the opinion of management that the Lehman Brothers Municipal Bond
      Index is a more appropriate broad-based benchmark for the market in which
      the Pennsylvania Portfolio invests rather than the Lehman Brothers
      Municipal Long Bond Index. In future reporting, the Lehman Brothers
      Municipal Bond Index and the Lehman Brothers Pennsylvania Municipal Bond
      Index will be used as a basis of comparison of total return performance
      rather than the Lehman Brothers Municipal Long Bond Index. The Lehman
      Brothers Municipal Long Bond Index (consisting of maturities of at least
      22 years) and the Lehman Brothers Pennsylvania Municipal Bond Index
      (consisting of Pennsylvania municipal bonds) are each a sub-index of the
      Lehman Brothers Municipal Bond Index, a broad-based, total return index
      comprised of investment grade, fixed rate municipal bonds selected from
      issues larger than $50 million issued since January 1991. Each index is
      unmanaged and is not subject to the same management and trading expenses
      of a mutual fund.

Bond Ratings (unaudited)
- --------------------------------------------------------------------------------

All ratings are by Standard & Poor's Ratings Service ("Standard & Poor's"),
except those that are identified by an asterisk (*) are rated by Moody's
Investors Service, Inc. ("Moody's") or those that are identified by a double
dagger (++) are rated by Fitch IBCA, Inc. ("Fitch"). The definitions of the
applicable rating symbols are set forth below:

Standard & Poor's -- Ratings from "AA" to "B" may be modified by the addition of
a plus (+) or minus (-) sign to show relative standings within the major rating
categories.

AAA      -- Bonds rated "AAA" have the highest rating assigned by Standard &
            Poor's. Capacity to pay interest and repay principal is extremely
            strong. 

AA       -- Bonds rated "AA" have a very strong capacity to pay interest and
            repay principal and differ from the highest rated issue only in a
            small degree.

A        -- Bonds rated "A" have a strong capacity to pay interest and repay
            principal although they are somewhat more susceptible to the adverse
            effects of changes in circumstances and economic conditions than
            bonds in higher rated categories.

BBB      -- Bonds rated "BBB" are regarded as having an adequate capacity to
            pay interest and repay principal. Whereas they normally exhibit
            adequate protection parameters, adverse economic conditions or
            changing circumstances are more likely to lead to a weakened
            capacity to pay interest and repay principal for bonds in this
            category than in higher rated categories.

BB       -- Bonds rated "BB" and "B" are regarded, on balance, as predominantly 
and B       speculative with respect to the issuer's capacity to pay interest
            and repay principal in accordance with the terms of the obligation.
            "BB" indicates the lowest degree of speculation and "B" the highest
            degree of speculation. While such bonds will likely have some
            quality and protective characteristics, these are outweighed by
            large uncertainties or major risk exposures to adverse conditions.
            
Moody's -- Numerical modifiers 1, 2, and 3 may be applied to each generic rating
from "Aa" to "Ba", where 1 is the highest and 3 the lowest rating within its
generic category.

Aaa      -- Bonds rated "Aaa" are judged to be of the best quality. They
            carry the smallest degree of investment risk and are generally
            referred to as "gilt edge." Interest payments are protected by a
            large or by an exceptionally stable margin and principal is secure.
            While the various protective elements are likely to change, such
            changes as can be visualized are most unlikely to impair the 
            fundamentally strong position of such issues.

Aa       -- Bonds rated "Aa" are judged to be of high quality by all
            standards. Together with the "Aaa" group they comprise what are
            generally known as high grade bonds. They are rated lower than the
            best bonds because margins of protection may not be as large as in
            "Aaa" securities or fluctuation of protective elements may be of
            greater amplitude or there may be other elements present which make
            the long-term risks appear somewhat larger than in "Aaa" securities.

A        -- Bonds rated "A" possess many favorable investment attributes and
            are to be considered as upper medium grade obligations. Factors
            giving security to principal and interest are considered adequate
            but elements may be present which suggest a susceptibility to
            impairment some time in the future.

Baa      -- Bonds rated "Baa" are considered to be medium grade obligations,
            i.e., they are neither highly protected nor poorly secured. Interest
            payments and principal security appear adequate for the present but
            certain protective elements may be lacking or may be
            characteristically unreliable over any great length of time. Such
            bonds lack outstanding investment characteristics and in fact have
            speculative characteristics as well.

Ba       -- Bonds rated "Ba" are judged to have speculative elements; their
            future cannot be considered as well assured. Often the protection of
            interest and principal payments may be very moderate, and thereby
            not well safeguarded during both good and bad times over the future.
            Uncertainty of position characterizes in this class.

Bond Ratings (unaudited) (continued)
- --------------------------------------------------------------------------------

Fitch    -- Ratings may be modified by the addition of a plus (+) sign or
            minus (-) sign to show relative standings within the major rating
            categories.

BBB      -- Bonds rated "BBB" by Fitch currently have a low expectation of
            credit risk. The capacity for timely payment of financial
            commitments is considered to be adequate. Adverse changes in
            economic conditions and circumstances, however, are more likely to
            impair this capacity. This is the lowest investment grade category
            assigned by Fitch.

NR       -- Indicates that the bond is not rated by Standard & Poor's,
            Moody's or Fitch.

- --------------------------------------------------------------------------------
Short-Term Security Ratings (unaudited)
- --------------------------------------------------------------------------------

SP-1     -- Standard & Poor's highest rating indicating very strong or strong
            capacity to pay principal and interest; those issues determined to
            possess overwhelming safety characteristics are denoted with a plus
            (+) sign.

A-1      -- Standard & Poor's highest commercial paper and variable-rate
            demand obligation (VRDO) rating indicating that the degree of safety
            regarding timely payment is either overwhelming or very strong;
            those issues determined to possess overwhelming safety
            characteristics are denoted with a plus (+) sign.

P-1      -- Moody's highest rating for commercial paper and for VRDO prior to
            the advent of the VMIG 1 rating.

VMIG 1   -- Moody's highest rating for issues having a demand feature --
            VRDO.

VMIG 2   -- Moody's second highest rating for issues having a demand
            feature -- VRDO.

1. Significant Accounting Policies

The Georgia and Pennsylvania Portfolios ("Portfolios") are separate investment
portfolios of the Smith Barney Muni Funds ("Fund"). The Fund, a Massachusetts
business trust, is registered under the Investment Company Act of 1940, as
amended, as an open-end management investment company and consists of these
Portfolios and six other separate investment portfolios: Florida, New York,
National, Limited Term, California Money Market and New York Money Market
portfolios. The financial statements and financial highlights for the other
portfolios are presented in separate semi-annual reports.

The significant accounting policies consistently followed by the Portfolios are:
(a) security transactions are accounted for on trade date; (b) securities are
valued at the mean between the bid and ask prices provided by an independent
pricing service that are based on transactions in municipal obligations,
quotations from municipal bond dealers, market transactions in comparable securi
ties and various relationships between securities; (c) securities for which
market quotations are not available will be valued in good faith at fair value
by or under the direction of the Board of Trustees; (d) securities maturing
within 60 days are valued at cost plus accreted discount or minus amortized
premium, which approximates value; (e) gains or losses on the sale of securities
are calculated by using the specific identification method; (f) interest
income, adjusted for amortization of premium and original issue discount, is
recorded on an accrual basis; market discount is recognized upon the
disposition of the security; (g) dividends and distributions to shareholders are
recorded on the ex-dividend date; (h) direct expenses are charged to each
Portfolio and each class; management fees and general fund expenses are
allocated on the basis of relative net assets; (i) each Portfolio intends to
comply with the applicable provisions of the Internal Revenue Code of 1986, as
amended, pertaining to regulated investment companies and to make
distributions of taxable income sufficient to relieve it from substantially all
Federal income and excise taxes; (j) the character of income and gains to be
distributed are determined in accordance with income tax regulations which may
differ from generally accepted accounting principles; and (k) estimates and
assumptions are required to be made regarding assets, liabilities and changes in
net assets resulting from operations when financial statements are prepared.
Changes in the economic environment, financial markets and any other parameters
used in determining these estimates could cause actual results to differ.

2. Portfolio Concentration

Since the Georgia and Pennsylvania Portfolios invest primarily in obligations of
issuers within Georgia and Pennsylvania, respectively, each Portfolio is subject
to possible concentration risks associated with economic, political, or legal
developments or industrial or regional matters specifically affecting the
respective state in which it invests.

3. Exempt-Interest Dividends and Other Distributions

Each Portfolio intends to satisfy conditions that will enable interest from
municipal securities, which is exempt from regular Federal income tax and from
designated state income taxes, to retain such tax-exempt status when distributed
to the shareholders of the Portfolio.

Capital gain distributions, if any, are taxable to shareholders, and are
declared and paid at least annually.

4. Management Agreement and Other Transactions

Mutual Management Corp. ("MMC"), a subsidiary of Salomon Smith Barney Holdings
Inc. ("SSBH"), acts as investment manager to the Portfolios. The Portfolios pay
MMC a management fee calculated at an annual rate of 0.45% of their respective
average daily net assets. This fee is calculated daily and paid monthly. MMC
waived a portion of its management fees for the Portfolios for the six months
ended September 30, 1998.

On October 8, 1998, CFBDS, Inc. became the Fund's distributor. Prior to that
date Salomon Smith Barney Inc. ("SSB"), was the Fund's distributor. SSB (as well
as certain other broker-dealers) continues to sell Fund shares to the public as
a member of the selling group.

On June 12, 1998, the Fund's existing Class C shares were renamed Class L
shares. Effective June 15, 1998, Class L shares are being sold at net asset
value plus a maximum initial sales charge of 1.00%. Class L shares also have a
1.00% contingent deferred sales charge ("CDSC"), which applies if redemption
occurs within the first year of purchase.

There is also a CDSC of 4.50% on Class B shares, which applies if redemption
occurs less than one year from initial purchase. This CDSC declines by 0.50% the
first year after purchase and by 1.00% per year until no CDSC is incurred. In
certain cases, Class A shares have a 1.00% CDSC, which applies if redemption
occurs within the first year of purchase. This CDSC only applies to those
purchases of Class A shares, which, when combined with current holdings of Class
A shares, equal or exceed $500,000 in the aggregate. These purchases do not
incur an initial sales charge.

Pursuant to a Distribution Plan, the Portfolios pay a service fee with respect
to Class A, B and L shares calculated at an annual rate of 0.15% of the average
daily net assets of each respective class. The Portfolios also pay a
distribution fee with respect to Class B and L shares calculated at an annual
rate of 0.50% and 0.55% of the average daily net assets of each class,
respectively.

For the six months ended September 30, 1998, total Distribution Plan fees
incurred were:

6. Shares of Beneficial Interest

At September 30, 1998, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Portfolios have
the ability to issue multiple classes of shares. Each share of a class
represents an identical interest in its respective Portfolio and has the same
rights, except that each class bears certain expenses specifically related to
the distribution of its shares. Effective June 12, 1998, the Fund adopted the
renaming of existing Class C shares as Class L shares.

At September 30, 1998, total paid-in capital amounted to the following for each
class and their respective Portfolio:

(2)   Per share amounts have been calculated using the monthly average shares
      method, rather than the undistributed net investment income method,
      because it more accurately reflects the per share data for the period.
(3)   For the period from April 4, 1994 (inception date) to March 31, 1995.
(4)   On October 10, 1994, the former Class C shares were exchanged into Class A
      shares.
(5)   The Manager has waived all or part of its fees for the six months ended
      September 30, 1998 and the years ended March 31, 1998, 1997 and 1996 and
      the period ended March 31, 1995. In addition, the Manager reimbursed
      expenses of $23,433 and $32,063 for the year ended March 31, 1996 and the
      period ended March 31,1995, respectively. If such fees were not waived and
      expenses not reimbursed, the effect on net investment income and expense
      ratios would have been as follows:

DEAR SHAREHOLDER:

We are pleased to provide you with the semi-annual report for the Smith Barney
Muni Funds - New York Money Market Portfolio and New York Portfolio
("Portfolios") for the period ended September 30, 1998. For your convenience, we
have summarized the period's prevailing economic and market conditions below and
outlined each Portfolio's investment strategy. A detailed summary of performance
can be found in the appropriate sections that follow.

NEW YORK MONEY MARKET PORTFOLIO
The New York Money Market Portfolio seeks to provide investors with income
exempt from federal income tax (other than the alternative minimum tax) and New
York State and City personal income taxes by investing in a portfolio of high
quality, short-term New York municipal obligations selected for liquidity and
stability of principal.

As of September 30, 1998, the Portfolio's 7-day current yield was 3.12%. The
Portfolio's 7-day effective yield, which reflects compounding, was 3.17%.

The Portfolio invests only in short-term securities that carry minimal credit
risk. All of the Portfolio's holdings are rated within the top two short-term
credit rating categories or are of comparable quality. During the reporting
period, the Portfolio's average weighted maturity was approximately 51 days.

While the Portfolio seeks to maintain a stable net asset value of $1.00 per
share, there can be no assurance this goal will be achieved. The U.S. government
neither insures nor guarantees an investment in the New York Money Market
Portfolio.

NEW YORK PORTFOLIO'S PERFORMANCE AND INVESTMENT STRATEGY
The New York Portfolio seeks to pay its shareholders as high a level of monthly
income exempt from Federal income taxes and from New York State and City

For the six months ended September 30, 1998, the Class A shares of the New York
Portfolio generated a total return of 4.78% and outperformed its New York
municipal bond fund peer group average total return of 4.49% for the same time
period, according to Lipper Analytical Services, Inc. (Lipper is an independent
fund-tracking organization.)

Based on its net asset value ("NAV") of $14.21 as of September 30, 1998 and the
current monthly income dividend of $0.058 for Class A, this equates to an
annualized distribution rate of 4.90%. For a New York resident in the combined
federal and state income tax bracket of 43.22%, the New York Portfolio's
tax-free yield of 4.90% is equivalent to a taxable yield of 8.63%. (This figure
assumes a federal income tax bracket of 36.0%, which represents 10.0% of all
U.S. federal taxpayers according to the Internal Revenue Service.) For
performance information on the Portfolio's other share classes, please see pages
6 and 7.

We are pleased to report that the Fund has been given a four-star rating overall
for its Class A and Class B shares from Morningstar, Inc.* as of September 30,
1998.

Given the present market conditions, we have continued to emphasize credit
quality and call protection in the Portfolio. As of the close of the reporting
period 91% of the Portfolio's bond holdings were rated "A" or better and average
stated call protection was 8.8 years. The Portfolio's holdings were concentrated
among the following industries: hospital bonds (14.7%), education bonds (11.9%),
transportation bonds (11.4%), pre-refunded bonds (11.0%) and housing bonds
(10.2%).

MARKET AND ECONOMIC OVERVIEW
Bond market performance was shaped primarily by surging demand for U.S. Treasury
securities and a massive issuance of municipal bonds in the past six months.
During the reporting period, municipal bond prices remained relatively flat with
coupon interest providing most of the returns for municipal bonds.

Troubled financial markets abroad and a strengthening U.S. dollar further
exacerbated an already dramatic flight of capital from foreign countries into
U.S. markets. The U.S. Treasury bond, considered to be the global benchmark for
credit quality, was the chief beneficiary of these capital inflows. The large
flows of money into U.S. Treasury securities drove their prices upward and their
yields lower. On September 30, 1998, the yield of the bellwether 30-year U.S.
Treasury bond fell to 4.95%, the lowest level for long-term government debt
since 1967. Since the close of the reporting period, long-term U.S. Treasury
yields fell even further before drifting upward in recent days.

Up until July, many bond investors had been focused on any signs of the
reappearance of inflation. However, developments in the Pacific Rim, such as
Japan's failure to shore up its ailing banking system and Russia's unexpected
devaluation of its currency, altered that view considerably. Moreover, a number
of speculators who found themselves caught in highly unusual market conditions
added to the growing uncertainty in U.S. capital markets.

In response to global tumult, the Federal Reserve Board ("Fed") signaled a shift
in policy from vigilance against inflation toward concerns of global deflation
by cutting short-term interest rates 0.25% at its September 1998 meeting. The
rate cut was the first action by the Fed since March 1997.

After the close of the reporting period, the Fed took an extraordinary and
unexpected action of cutting short-term interest rates again by another 0.25% on
October 15, 1998. This latest action brings the federal-funds rate to 5.0% and
the largely symbolic discount rate to 4.75%. (The federal-funds rate is the
interest rate banks charge each other for overnight loans and a closely watched
indicator of the direction of interest rates. The discount rate is the interest
rate the Federal Reserve charges its member banks for loans.)

Foreign investors, who do not benefit from the tax-exempt status of municipal
bonds, have been large buyers of U.S. Treasury securities. As a result, yields
for U.S. Treasury securities have declined further than those of municipal
bonds. Municipal bond yields are currently yielding as much as 100% of
equivalent maturity U.S. Treasury bonds. Municipal bonds are considered by many
investors to be a good value when they yield about 85% of U.S. Treasury bonds.
At their present levels, we believe that tax-exempt bonds can now provide a
competitive income stream for risk-averse investors of almost any income tax
bracket.

In contrast to the diminishing U.S. Treasury security supply, municipal bond
issuance continued at record levels. New issue volume reached its peak in 1993
when $293 billion in new municipal bonds were sold. So far this year, municipal
bond volume is on pace to exceed $300 billion. This disparity in supply and

demand between U.S. Treasury bonds and municipal bonds is a primary reason for
municipal bond underperformance relative to U.S. Treasurys.

NEW YORK ECONOMIC HIGHLIGHTS
Economic recovery continued in New York State, driven mostly by a booming
downstate economy. Employment in New York City grew at its fastest pace in
decades accompanied by real gains in wages. The service sector, especially
financial services and tourism industries, continues to fuel the economic
expansion in New York. In addition, the tremendous success of Wall Street in
recent years has helped revive a previously floundering real estate market and
has also led to higher spending in the adjacent suburbs. As a result of the
increased economic activity, New York City generated a record budget surplus of
$2.1 billion in fiscal year 1998.

Nonetheless, the Empire State may soon be feeling the effects of the spreading
global deflationary pressures. A number of prominent Wall Street firms have
already reported diminished earnings and downsizing as a direct result of the
recent market turmoil. Although we expect New York City to experience declining
revenues, it should not result in budget shortfalls as in previous market
downturns because New York City officials have already begun to lower its
financial forecasts. Because Wall Street is such a significant contributor to
New York City's financial health, as well as New York State, its near-term
prospects will be closely tied to the resolution of current market unrest.
However, we continue to be optimistic about New York's long-term financial
future.

OUTLOOK
We believe that municipal bonds represent excellent values under the current
market conditions. With the stock market's recent volatility, many investors may
be looking to reallocate their existing portfolios. In our opinion, this may be
a timely opportunity for many of these investors to consider further
diversifying their portfolios with municipal bonds.

We anticipate that economic conditions should remain supportive for the
municipal bond market over the near term. The U.S. economy remains sound despite
the widely reported economic distress of many other countries. Although U.S.
economic growth will likely slow over the coming months, we expect the economy
to expand modestly. Moreover, the Fed should continue to gradually lower
short-term interest rates and that in turn should help correct some of the
imbalances that exist in the overall bond market today.

On a more somber note, we report with much sadness the passing of Emeritus
Trustee C. Richard Youngdahl. Dick made many valuable contributions to the Board
and the Fund during his tenure and he will be missed.

+     Hypothetical illustration of $10,000 invested in Class A shares on
      September 30, 1988, assuming deduction of the maximum 4.00% sales charge
      at the time of investment and reinvestment of dividends (after deduction
      of applicable sales charges through November 6, 1994 and thereafter at net
      asset value) and capital gains, if any, at net asset value through
      September 30, 1998. The performance of the Portfolio's other classes may
      be greater or less than the Class A shares' performance indicated on this
      chart, depending on whether greater or lesser sales charges and fees were
      incurred by shareholders investing in the other classes.

      All figures represent past performance and are not a guarantee of future
      results. Investment returns and principal value will fluctuate, and
      redemption values may be more or less than the original cost. No
      adjustment has been made for shareholder tax liability on dividends or
      capital gains.

*     It is the opinion of management that the Lehman Brothers Municipal Bond
      Index is a more appropriate broad-based benchmark for the market in which
      the New York Portfolio invests, rather than the Lehman Brothers Municipal
      Long Bond Index. In future reporting, the Lehman Brothers Municipal Bond
      Index will be used as a basis of comparison of total return performance
      rather than the Lehman Brothers Municipal Long Bond Index. The Lehman
      Brothers Municipal Long Bond Index (consisting of maturities of at least
      22 years) is a sub-index of the Lehman Brothers Municipal Bond Index, a
      broad-based, total return index comprised of investment grade, fixed rate
      municipal bonds selected from issues larger than $50 million issued since
      January 1991. Each index is unmanaged and is not subject to any management
      and trading expenses of a mutual fund.

Bond Ratings (unaudited)
- --------------------------------------------------------------------------------

All ratings are by Standard & Poor's Ratings Services ("Standard & Poor's"),
except those which are identified by an asterisk (*) are rated by Moody's
Investors Service Inc. ("Moody's"). The definitions of the applicable rating
symbols are set forth below:

Standard & Poor's -- Ratings from "AA" to "BB" may be modified by the addition
of a plus (+) or minus (-) sign to show relative standings within the major
rating categories.

AAA     -- Bonds rated "AAA" have the highest rating assigned by Standard &
           Poor's. Capacity to pay interest and repay principal is extremely
           strong.
AA      -- Bonds rated "AA" have a very strong capacity to pay interest and
           repay principal and differ from the highest rated issue only in a
           small degree.
A       -- Bonds rated "A" have a strong capacity to pay interest and repay
           principal although they are somewhat more susceptible to the adverse
           effects of changes in circumstances and economic conditions than
           bonds in higher rated categories.
BBB     -- Bonds rated "BBB" are regarded as having an adequate capacity to pay
           interest and repay principal. Whereas they normally exhibit adequate
           protection parameters, adverse economic conditions or changing
           circumstances are more likely to lead to a weakened capacity to pay
           interest and repay principal for bonds in this category than in
           higher rated categories.
BB      -- Bonds rated "BB" have less near-term vulnerability to default than
           other speculative issues. However, they face major ongoing
           uncertainties of exposure to adverse business, financial, or economic
           conditions which could lead to inadequate capacity to meet timely
           interest and principal payments.

Moody's -- Numerical modifiers 1, 2 and 3 may be applied to each generic rating
from "Aa" to "B", where 1 is the highest and 3 the lowest ranking within its
generic category.

Aaa     -- Bonds rated "Aaa" are judged to be of the best quality. They carry
           the smallest degree of investment risk and are generally referred to
           as "gilt edge". Interest payments are protected by a large or by an
           exceptionally stable margin and principal is secure. While the
           various protective elements are likely to change, such changes as can
           be visualized are most unlikely to impair the fundamentally strong
           position of such issues.
Aa      -- Bonds rated "Aa" are judged to be of high quality by all standards.
           Together with the "Aaa" group they comprise what are generally known
           as high grade bonds. They are rated lower than the best bonds because
           margins of protection may not be as large as in "Aaa" securities or
           fluctuation of protective elements may be of greater amplitude or
           there may be other elements present which make the long-term risks
           appear somewhat larger than in "Aaa" securities.
A       -- Bonds rated "A" possess many favorable investment attributes and are
           to be considered as upper medium grade obligations. Factors giving
           security to principal and interest are considered adequate but
           elements may be present which suggest a susceptibility to impairment
           some time in the future.
Baa     -- Bonds rated "Baa" are considered as medium grade obligations, i.e.,
           they are neither highly protected nor poorly secured. Interest
           payments and principal security appear adequate for the present but
           certain protective elements may be lacking or may be
           characteristically unreliable over any great length of time. Such
           bonds lack outstanding investment characteristics and in fact have
           speculative characteristics as well.
Ba      -- Bonds rated "Ba" are judged to have speculative elements; their
           future cannot be considered as well assured. Often the protection of
           interest and principal payments may be very moderate thereby not well
           safeguarded during both good and bad times over the future.
           Uncertainty of position characterizes bonds in this class.
B       -- Bonds rated "B" generally lack characteristics of desirable
           investments. Assurance of interest and principal payments or of
           maintenance of other terms of the contract over any long period of
           time may be small.

NR      -- Indicates the bond is not rated by Standard & Poor's or Moody's.

Short-Term Security Ratings (unaudited)
- --------------------------------------------------------------------------------

SP-1    -- Standard & Poor's highest rating indicating very strong or strong
           capacity to pay principal and interest; those issues determined to
           possess overwhelming safety characteristics are denoted with a plus
           (+) sign.
A-1     -- Standard & Poor's highest commercial paper and variable rate demand
           obligation (VRDO) rating indicating that the degree of safety
           regarding timely payment is either overwhelming or very strong; those
           issues determined to possess overwhelming safety characteristics are
           denoted with a plus (+) sign.
P-1     -- Moody's highest rating for commercial paper and for VRDO prior to the
           advent of the VMIG 1 rating.
VMIG 1  -- Moody's highest rating for issues having a demand feature -- VRDO.
MIG 1   -- Moody's highest rating for short-term municipal obligations.
MIG 2   -- Moody's second highest rating for short-term municipal obligations.

1. SIGNIFICANT ACCOUNTING POLICIES

The New York Money Market and New York Portfolios ("Portfolios") are separate
investment portfolios of the Smith Barney Muni Funds ("Fund"). The Fund, a
Massachusetts business trust, is registered under the Investment Company Act of
1940, as amended, as an open-end management investment company and consists of
these Portfolios and six other separate investment portfolios: Florida, Georgia,
Pennsylvania, Limited Term, National and California Money Market Portfolios. The
financial statements and financial highlights for the other portfolios are
presented in separate semi-annual reports.

The significant accounting policies consistently followed by the Fund are: (a)
security transactions are accounted for on trade date; (b) securities are valued
at the mean between the quoted bid and ask prices provided by an independent
pricing service that are based on transactions in municipal obligations,
quotations from municipal bond dealers, market transactions in comparable
securities and various relationships between securities; (c) securities maturing
within 60 days are valued at cost plus accreted discount or minus amortized
premium, which approximates value; (d) securities for which market quotations
are not available will be valued in good faith at fair value by or under the
directions of the Board of Trustees; (e) gains or losses on the sale of
securities are calculated by using the specific identification method; (f)
interest income, adjusted for amortization of premium and accretion of original
issue discount, is recorded on an accrual basis; market discount is recognized
upon the disposition of the security; (g) dividends and distributions to
shareholders are recorded on the ex-dividend date; (h) direct expenses are
charged to each portfolio and each class; management fees and general fund
expenses are allocated on the basis of relative net assets; (i) the Portfolios
intend to comply with the applicable provisions of the Internal Revenue Code of
1986, as amended, pertaining to regulated investment companies and to make
distributions of taxable income sufficient to relieve them from substantially
all Federal income and excise taxes; (j) the character of income and gains to be
distributed are determined in accordance with income tax regulations which may
differ from generally accepted accounting principles; and (k) estimates and
assumptions are required to be made regarding assets, liabilities and changes in
net assets resulting from operations when financial statements are prepared.
Changes in the economic environment, financial markets and any other parameters
used in determining these estimates could cause actual results to differ.

2. PORTFOLIO CONCENTRATION

Since each Portfolio invests primarily in obligations of issuers within New
York, it is subject to possible concentration risks associated with economic,
political, or legal developments or industrial or regional matters specifically
affecting New York.

3. EXEMPT-INTEREST DIVIDENDS AND OTHER DISTRIBUTIONS

The New York Money Market Portfolio declares and records a dividend of
substantially all of its net investment income on each business day. Such
dividends are paid or reinvested monthly in Portfolio shares on the payable
date. Furthermore, each Portfolio intends to satisfy conditions that will enable
interest from municipal securities, which is exempt from Federal income tax and
from designated state income taxes, to retain such tax-exempt status when
distributed to the shareholders of the Portfolio.

Capital gain distributions, if any, are taxable to shareholders, and are
declared and paid at least annually.

4. MANAGEMENT AGREEMENT AND OTHER TRANSACTIONS

Mutual Management Corp. ("MMC"), a subsidiary of Salomon Smith Barney Holdings
Inc. ("SSBH"), acts as investment manager to the Fund. The New York Money Market
Portfolio pays MMC a management fee calculated at an annual rate of 0.50% on the
first $2.5 billion of average daily net assets; 0.475% on the next $2.5 billion
and 0.45% on the average daily net assets in excess of $5 billion. The New York
Portfolio pays MMC a management fee calculated at the annual rate of 0.50% of
its average daily net assets. These fees are calculated daily and paid monthly.

On October 8, 1998 CFBDS, Inc. became the Fund's distributor. Prior to that date
Salomon Smith Barney Inc. ("SSB"), was the Fund's distributor. SSB (as well as
certain other broker-dealers) continues to sell Fund shares to the public as
members of the selling group.

On June 12, 1998, the Fund's Class C shares were renamed Class L shares.
Effective June 15, 1998, Class L shares of the New York Portfolio are being sold
at net asset value plus a maximum initial sales charge of 1.00%. Class L shares
also have a 1.00% contingent deferred sales charge ("CDSC"), which applies if
redemption occurs within the first year of purchase.

There is also a CDSC of 4.50% on Class B shares of the New York Portfolio, which
applies if redemption occurs within one year from purchase. This CDSC declines
by 0.50% the first year after purchase and thereafter by 1.00% per year until no
CDSC is incurred. In addition, Class A shares of the New York Portfolio also
have a 1.00% CDSC, which applies if redemption occurs within the first year of
purchase. This CDSC only applies to those purchases of Class A shares, which,
when combined with current holdings of Class A shares, equal or exceed $500,000
in the aggregate. These purchases do not incur an initial sales charge.

average daily net assets of each respective class. In addition, the New York
Portfolio pays a distribution fee with respect to Class B and L shares
calculated at the annual rates of 0.50% and 0.55% of the average daily net
assets of each class, respectively.

At September 30, 1998, the aggregate gross unrealized appreciation and
depreciation of investments for Federal income tax purposes were substantially
as follows:

6. CAPITAL LOSS CARRYFORWARD

At March 31, 1998, the New York Money Market Portfolio had, for Federal income
tax purposes, $206,000 of loss carryforwards expiring March 31, 2000 which are
available to offset future capital gains. To the extent that these carryforward
losses are used to offset capital gains, it is probable that the gains so offset
will not be distributed.

7. SHARES OF BENEFICIAL INTEREST

At September 30, 1998, the Fund had an unlimited amount of shares of beneficial
interest authorized with a par value of $0.001 per share. The Portfolios have
the ability to issue multiple classes of shares. Each share of a class
represents an identical interest in its respective Portfolio and has the same
rights, except that each class bears certain expenses specifically related to
the distribution of its shares. Effective June 12, 1998, the Fund adopted the
renaming of existing Class C shares as Class L shares.

At September 30, 1998, total paid-in capital amounted to the following for each
class and their respective Portfolio:

Portfolio                             Class A          Class B         Class L
