Dear Fellow Shareholders:
 
     It is my pleasure to provide you with the semiannual report for Heritage
Series Trust for the period ended April 30, 1997. The four separate investment
portfolios available within Heritage Series Trust are the Eagle International
Equity Portfolio, the Growth Equity Fund, the Small Cap Stock Fund and the Value
Equity Fund. While historically we have provided these reports under separate
cover, we are now combining them continuing the process begun with our recently
combined prospectus updates. Because many of you have invested in more than one
of these funds, we are able to reduce the volume of mail you receive while still
providing important investment information on each of your investments. We hope
you will let us know how you like these changes. Please call us at 800-709-FUND
(3863) with any comments you would like to share.
 
     During the period covered by this report, the stock markets, both
domestically and internationally, continued to be quite volatile. Each of the
funds in the Heritage Series Trust delivered positive returns during this period
and, as shown in the table below, were very competitive relative to their
respective indices and fund category averages.

     In the pages that follow, you will find portfolio commentaries for these
funds, each followed by the investment portfolio information for the respective
fund. Following this information is other important financial information for
all of the funds.
 
     On behalf of all of us at Heritage, we appreciate the confidence you have
shown by your investments with us. We hope that you will discuss with your
financial advisors how other Heritage funds may fit in your investment plan. We
look forward to reporting to you again this fall after the end of the funds'
fiscal year.

MARKET COMMENTARY from MARTIN CURRIE, INC.                         June 11, 1997
Subadviser Eagle International Equity Portfolio
 
     The Eagle International Equity Portfolio is constructed with the goal of
outperforming the Morgan Stanley Capital International Europe, Australia, Far
East Index ("EAFE Index"). The countries in which it invests are selected for
their ability to generate high real rates of economic growth, consistent with
reasonable political and currency stability. Securities of industrial issuers
are selected following an intensive research process, designed to screen out
companies with either weak financial structures, market positions or poor
management. The ability to produce premium growth in earnings is paramount.
 
     Over the six months to 30 April 1997, international markets continued to
move ahead, helped by a recovery in non-index markets, particularly Latin
America. The Japanese market remained an exception, by weakening further. The
Fund rose by over 6% during the period, compared to a return of less than 2%
from the MSCI EAFE Index.
 
     CONTINENTAL EUROPEAN stock markets (34.2% of net assets as of April 30)
were robust during the period, helped by supportive bond markets and weak
currencies. Corporate restructuring provided additional impetus for markets to
move ahead. We added new holdings reflecting this restructuring theme over the
period, such as Rhone-Poulenc (France), Volkswagen (Germany), Philips
Electronics (Netherlands) and ABB (Sweden) reflect the restructuring themes.
 
     In the UNITED KINGDOM (19.0% of net assets), the equity market moved
strongly ahead through April 30, supported by benign economic news and good
liquidity. Financial stocks were significant outperformers. We added holdings in
Scottish Power (with utilities fully discounting a change of government). Royal
Bank of Scotland and General Electric (with new management now in place). For
Europe as a whole, a changed government in the UK and key elections in Europe
may well create further uncertainty over EMU convergence. Interest rates will
remain subdued and corporate activity will be sufficient to keep earnings moving
ahead. Valuations remain at attractive levels.
 
     The JAPANESE stock market (17.3% of net assets) weakened further through
April 30. We reduced our position and removed the currency protection against a
weaker yen. The real casualty of the recent fall in the Japanese Index has been
the financial sector, where we have remained very underweighted, preferring
manufacturing stocks, which are the beneficiaries of the yen's weakness and
corporate profit recovery. This strategy offset the worst of the index fall.
Monetary policy remains relaxed in the region and we are beginning to see some
signs of the yen firming and economic conditions improving. Such evidence points
to an increase in domestic and medium sized holdings within the portfolio.
International investors have returned to the market.
 
     ASIAN markets (16.6% of net assets) generally performed poorly as a region.
Singapore, The Philippines, South Korea and Thailand were very weak. Hong Kong,
Taiwan and Australia stood out in contrast. We added to Hong Kong over the
period, with holdings such as China Overseas Land benefiting from a gradual
recovery in China's economy and increased confidence over the transfer of
sovereignty. We have no exposure to Thailand, South Korea or Taiwan.
 
     Our response to SMALLER MARKETS has concentrated on LATIN AMERICA (7.4% of
net assets). Brazil and Peru were the top performing markets. We have had
overweighted positions in the key blue chip stocks such as Telebras, Petrobas
and Telefonica del Peru. We broadened both our market and stock exposure over
the period, through privatisations such as CTC (Chile) and CANTV (Venezuela).
Elsewhere, we invested in holdings from India, while decreasing our holdings in
Taiwan, because of improved political stability and market liquidity that saw
the market off its lows. We currently have no exposure to South Africa.
 
     In terms of our outlook, we believe the cycle of economic activity,
corporate profits and share prices in North America is now very extended. In
contrast, major international markets do not look expensive, particularly
relative to bonds.

     In the UK, a change of government should not impact dramatically on the
benign environment for equities. However, some uncertainty will prevail in the
short term over tax changes. In Continental Europe, where economic activity is
yet to revive, our investment theme is the change in management culture that
permits companies to be run for the benefit of shareholders rather than for
other groups.
 
     In Japan, we see an opportunity to take advantage of recovery in certain
sectors of the economy. In Asia, the dominant theme will be China. Some
opportunities again are appearing in the region as export growth recovers
elsewhere. In the smaller markets area, we believe Latin America offers the
greatest potential.
 
     We appreciate your confidence in investing with us. We look forward to
providing you a further update after the Fund's fiscal year.

Dear Fellow Shareholders:
 
     The Heritage Series Trust-Growth Equity Fund (the "Fund") has continued to
perform well over the last six months. The Fund currently has 31 equity
investments that we consider to be premier, quality growth stocks. Each company
is expected to grow its earnings at a minimum of 12% per year for the next three
years and maintain a 15% return on equity. In addition, we focus on owning
companies with consistent, predictable earnings and businesses that are
established and will maintain a competitive advantage in their industry.
 
     A predominant theme in the Fund's portfolio continues to be the ownership
of outstanding U.S. multinational companies that derive significant revenues and
earnings from overseas sales. Examples include: Coca Cola, Gillette, Procter &
Gamble, Johnson & Johnson, Merck, American International Group, and Illinois
Tool Works. Our technology exposure has remained constant at approximately 15%
with core investments in Intel, Microsoft, Cisco, and Oracle. Cyclicals and
energy related issues remain underweighted in our portfolio as they typically do
not meet our investment criteria. Other stocks that have significantly
contributed to our performance results include: Omnicom, Kohl's and Home Depot.
 
     We continue to invest new cash flows to keep the Fund fully invested with
cash levels under 10%. Annual portfolio turnover remains in the 25%-50% range.
 
     The past six months has been characterized by tremendous volatility. As of
mid-February the Fund was up approximately 12% from January 1, 1997. However,
inflation fears and a Federal Reserve Board's (the "Fed") interest rate increase
quickly eroded our gains. Historically, rising interest rates have not been a
hospitable environment for growth investors as higher bond yields attract
capital and future earnings are discounted to be less valuable. However, since
the quarter end, recent economic data indicates that the economy is slowing
naturally. The market speculates that inflation may be under control and the Fed
may not need to raise rates further. This has been extremely positive for our
quality growth stocks and has provided a powerful rebound for the Fund.
 
     Going forward, we continue to see robust earnings for our companies and a
relatively hospitable investment environment for quality growth companies.
 
                                              Sincerely,
 
                                              /s/ KENNETH W. CORBA

Dear Fellow Shareholders:
 
     We look forward with enthusiasm to making additional progress in building
the value of the portfolio of the Heritage Small Cap Stock Fund (the "Fund").
 
     The basic building blocks of the financial market remain good: growing
corporate profits, excellent competitiveness of U.S. companies, low inflation,
foreign interest in U.S. equities, movement toward balanced budgets, demand for
financial assets by aging baby boomers and reasonable valuations.
 
     Over the past twelve months, the price appreciation of the largest issues
has far exceeded that of the Russell 2000 as a result of investor interest in
index funds. This has resulted in significant undervaluation of small cap stocks
relative to large cap stocks.
 
     We believe this valuation dispersion is unsustainable and should be
accompanied by excellent performance in the small capitalization sectors. As we
go to press, this valuation dispersion has just begun to be corrected and
momentum appears to be moving toward small cap equities. We believe this should
lead to sound investment results for your Fund.
 
     With respect to our part of your Fund's portfolio, our large exposure in
data processing and electronics industries recognizes efforts to improve
productivity by the corporate sector. Similarly, the significant exposure to
medical equipment reflects the need of our society to serve an aging population
in a cost efficient manner.
 
     We hold a large position in the oil and gas industry as the long-term
supply/demand equation has become favorable and equity prices are attractively
valued.
 
     Many small capitalization issues are so attractively priced that we are
seeing some of the issuers of our holdings being taken over by large companies.
This reflects the compelling valuations. These valuations give us confidence
about the future performance of the Fund.
 
     We look forward to continuing to serve you as portfolio manager on our
portion of your Fund's assets.
 
                                          Sincerely,
 
                                        /s/ JAMES D. AWAD

Dear Fellow Shareholders:
 
     It is a pleasure to be able to report to you that, during a period of
extremely poor relative performance for small capitalization stocks (small
caps), The Heritage Small Cap Stock Fund continued to perform well, appreciating
by 5.9%* on the A shares for the six months ended April 30, 1997. During that
period the Russell 2000 was up only 1.6%.
 
     For the 12 months ended April 30, 1997, small caps, as measured by the
Russell 2000 Index, underperformed the Standard & Poor's 500 Index by some 25%.
According to a study by Prudential Securities, similar relative underperformance
on the part of small caps last occurred in the period ended October 1990. The
study indicates in the six months following October 1990, small caps
outperformed large capitalization stocks by about 15%. Although I don't ascribe
to market timing, given the underperformance of small caps, their relatively
attractive recent valuations, when compared to large capitalization stocks,
coupled with favorable prospects for a capital gains tax cut, a case can be
built for strong small cap performance over the next twelve months. In fact,
small cap stocks have performed very well since the end of April.
 
     In our portion of your Fund's portfolio, the following mergers contributed
to your Fund's strong performance during the six months ended April 30, 1997:
BHC Financial, Inc. with Fiserve, Inc. and National Education Corp. with
Harcourt General, Inc.
 
     Strong performers also included, full service hotel operators CapStar Hotel
Company and Bristol Hotels; educational service providers, Strayer Education
Corporation and Houghton Mifflin Company; regional stockbrokers, Legg Mason,
Inc. and Southwest Securities Group, Inc. and retailers, Genesco Inc., Cole
National Corporation, and Claire's Stores, Inc.
 
     On the downside, losses were relatively minor, but included Forensic
Technologies International Corporation, and Envirosource, Inc., while Ampex
Corporation and Sodak Gaming, Inc. retraced prior gains. A relatively light
weighting in the battered technology sector aided performance.
 
     Recently, we have purchased several telecommunications and electronic
companies including SymmetriCom, Inc., Sawtek, Inc., and Triquint Semiconductor,
Inc. Other new purchases include oil service provider Seacor Smit, Inc. as well
as Chicago Miniature Lamp, Inc. Subsequent to April 30, 1997, we also augmented
our holdings of regional stock brokers, with purchases of Interra Financial,
Inc. and Advest Group, Inc.
 
     Recent sales included Marine Drilling Companies, Inc., Bristol Hotel
Corporation, as well as relatively small positions in Aronex Pharmaceuticals,
Inc. and Kapson Senior Quarters Corporation. National Education Corporation was
sold upon learning that Nick Acquisition Corporation, a wholly-owned subsidiary
of Harcourt General Inc., offered to purchase all of its outstanding shares.
 
     I am excited about the future and remain dedicated to do my best for fund
shareholders.
 
                                          Sincerely,
 
                                          /s/ BERT BOKSEN

MARKET COMMENTARY from DREMAN VALUE ADVISORS, INC.
Subadviser - Value Equity Fund
 
     We are pleased to present to you the semiannual report for the Heritage
Series Trust - Value Equity Fund for the six month period ended April 30, 1997.
The Fund provided a total return of 12.62%* for Class A Shares and 12.29%* for
Class C Shares during the period.
 
     In this period, fund managers in general trailed the Standard & Poor's ("S
& P") 500 Index as evidenced by the 10.2% return of the Lipper Growth and Income
category of mutual funds. This phenomenon is the result of the relatively narrow
advance in the market and the so-called "nifty 50" effect. In this period, the
50 stocks which comprise the Morgan Stanley Nifty 50 Index gained a remarkable
22.1%. These stocks inflated the returns of the S & P 500 Index. This market
incongruity has appeared briefly in various market cycles over the last three
decades only to revert to a more normal distribution of returns among equity
securities.
 
     Despite the recent rise to new all time highs in the major market averages
in recent months, the market has been quite volatile as investor perceptions and
expectations regarding the economy, inflation, interest rates and profits have
been more mercurial than the underlying fundamentals.
 
     Your Fund's holdings are well-diversified among seasoned quality leaders
within their industries. The top ten holdings, which comprised approximately 24%
of assets as of April 30, are Mobil Corporation, Student Loan Marketing
Association, PepsiCo, Inc., Illinois Tool Works, Inc., Exxon Corporation, Philip
Morris Companies, Inc., RJR Nabisco Holdings Corporation, Federal Express
Corporation, Raytheon Corporation and Fannie Mae.
 
     Recent additions to our basic industry holdings, which comprise
approximately 12% of the portfolio holdings, are diversified within the paper,
chemical and steel industries and have begun to respond favorably in the market
place.
 
     Although the major market averages have made new highs, the majority of
stocks have not performed as well as these indicators suggest. This factor
leaves opportunities for disciplined value investors to uncover the leaders of
tomorrow. We believe your portfolio, which has a price-earnings ratio below the
market, a higher dividend yield than the market as historic and projected
earnings growth which is above the market, is well positioned for the future.
 
     We look forward to continuing to serve you as subadviser to the Heritage
Value Equity Fund.

Note 1: SIGNIFICANT ACCOUNTING POLICIES.  Heritage Series Trust (the "Trust") is
        organized as a Massachusetts business trust and is registered under the
        Investment Company Act of 1940, as amended, as a diversified, open-end
        management investment company and presently offers shares in four
        series, the Eagle International Equity Portfolio, the Growth Equity
        Fund, the Small Cap Stock Fund, and the Value Equity Fund (each, a
        "Fund" and collectively, the "Funds"). The Eagle International Equity
        Portfolio primarily seeks capital appreciation principally through
        investment in an international portfolio of equity securities. The
        Growth Equity Fund primarily seeks growth through long-term capital
        appreciation. The Small Cap Stock Fund seeks long-term capital
        appreciation by investing principally in the equity securities of
        companies with small market capitalization that the Fund's investment
        subadvisers believe are undervalued and therefore offer above-average
        potential for long-term capital appreciation. The Value Equity Fund
        primarily seeks long-term capital appreciation and, secondarily, seeks
        current income. The Funds currently offer Class A and Class C Shares.
        Class A Shares are sold subject to a maximum sales charge of 4.75% of
        the amount invested payable at the time of purchase. Class C Shares, are
        sold subject to a contingent deferred sales charge of 1% of the lower of
        net asset value or purchase price payable upon any redemptions within
        one year after purchase. The Eagle International Equity Portfolio also
        issues Eagle Class Shares, which are subject to certain minimum
        investment requirements and are sold without any sales charge. The
        preparation of financial statements in accordance with generally
        accepted accounting principles requires management to make estimates and
        assumptions that affect the reported amounts and disclosures. Actual
        results could differ from those estimates. The following is a summary of
        significant accounting policies:
 
        Security Valuation: Each Fund values investment securities at market
        value based on the last quoted sales price as reported by the principal
        securities exchange on which the security is traded. If no sale is
        reported, the last bid price is used and in the absence of a market
        quote, securities are valued using such methods as the Board of Trustees
        believes would reflect fair market value. Securities that are quoted in
        a foreign currency will be valued daily in U.S. dollars at the foreign
        currency exchange rates prevailing at the time the Eagle International
        Equity Portfolio calculates its daily net asset value per share.
        Although the Eagle International Equity Portfolio values its assets in
        U.S. dollars on a daily basis, it does not intend to convert holdings of
        foreign currencies into U.S. dollars on a daily basis. Short term
        investments having a maturity of 60 days or less are valued at cost
        which, when combined with accrued interest included in interest
        receivable or discount earned, approximates market.
 
        Foreign Currency Transactions: The books and records of the Eagle
        International Equity Portfolio are maintained in U.S. dollars. Foreign
        currency transactions are translated into U.S. dollars on the following
        basis: (i) market value of investment securities, other assets and other
        liabilities at the daily rates of exchange, and (ii) purchases and sales
        of investment securities, dividend and interest income and certain
        expenses at the rates of exchange prevailing on the respective dates of
        such transactions. The Eagle International Equity Portfolio does not
        isolate that portion of gains and losses on investments which is due to
        change in foreign exchange rates from that which is due to changes in
        market prices of the investments. Such fluctuations are included with
        the net realized and unrealized gains and losses from investments. Net
        realized gain (loss) and unrealized appreciation (depreciation) from
        currency transactions include gains and losses between trade and
        settlement date on securities transactions, gains and losses arising
        from the sales of foreign currency and gains and losses between the ex
        and payment dates on dividends, interest, and foreign withholding taxes.
 
        Forward Foreign Currency Contracts: The Eagle International Equity
        Portfolio may enter into forward foreign currency contracts which are
        valued daily at the appropriate exchange rates. The resultant unrealized
        exchange gains and losses are included in the Statement of Operations as
        unrealized foreign currencies gain or loss. The Eagle International
        Equity Portfolio records realized gains or losses on delivery of the
        currency or at the time the forward contract is extinguished
        (compensated) by entering into a closing transaction prior to delivery.
 
        Repurchase Agreements: Each Fund enters into repurchase agreements
        whereby a Fund, through its custodian, receives delivery of the
        underlying securities, the market value of which at the time of purchase
        is required to be in an amount equal to at least 100% of the resale
        price.
 
        Federal Income Taxes: Each Fund is treated as a single corporate
        taxpayer and provided for in the Tax Reform Act of 1986, as amended. A
        Fund's policy is to comply with the requirements of the Internal Revenue
        Code of 1986, as amended, which are applicable to regulated investment
        companies and to distribute substantially all of its taxable income to
        its shareholders. Accordingly, no provision has been made for federal
        income and excise taxes.
 
        Distribution of Net Realized Gains. Net realized gains from investment
        transactions during any particular year in excess of available capital
        loss carryforwards, which, if not distributed, would be taxable to each
        Fund, will be distributed to shareholders in the following fiscal year.
        Each Fund uses the identified cost method for determining realized gain
        or loss on investments for both financial and federal income tax
        reporting purposes.
 
        State Registration Expenses: State registration fees are amortized based
        either on the time period covered by the registration or as related
        shares are sold, whichever is appropriate for each state.
 
        Expenses: Each Fund is charged for those expenses that are directly
        attributable to it, such as management fee, custodian/fund accounting
        fees, distribution fee, etc., while other expenses such as professional
        fees, insurance expense, etc., are all allocated proportionately among
        the Trust. Expenses of each Fund are allocated to each class of shares
        based upon their relative percentage of current net assets. All expenses
        that are directly attributable to a specific class of shares, such as
        distribution fees and shareholder service fees with respect to Eagle
        International Equity Portfolio, are allocated to that class.
 
        Organization Expenses: Expenses incurred in connection with the
        formation of each Fund were deferred and are being amortized on a
        straight-line basis over 60 months from the date of commencement of
        operations.
 
        Capital Accounts: Each Fund reports the undistributed net investment
        income and accumulated net realized gain (loss) accounts on a basis
        approximating amounts available for future tax distributions (or to
        offset future taxable realized gains when a capital loss carryforward is
        available). Accordingly, each Fund may periodically make
        reclassifications among certain capital accounts without impacting the
        net asset value of the Fund.
 
        Other: Investment security transactions are accounted for on a trade
        date plus one basis. Dividend income and distributions to shareholders
        are recorded on the ex-dividend date. Interest income is recorded on the
        accrual basis.

         Manager a portion or all of the waived management fee. In addition, the

         Effective March 1, 1997, the Manager has voluntarily agreed to waive

         operating expenses exceed 1.60% for Class A Shares and 2.35% for Class

         Management fees of $9,784 were waived for the six month period ended

         limitation agreed to by the Manager before the end of the year ending
         October 31, 1999, the Fund may be required to pay the Manager a portion
         or all of the waived management fee. In addition, the Fund may be

         The Manager has entered into an agreement with Eagle Asset Management,

         equal to 50% of the fees payable by the Fund to the Manager with
         respect to the assets allocated to Eagle, without regard to any

         respect to the assets allocated to Dreman. If, however, the manager's
         fee is reduced due to the imposition of asset level breakpoints,
         Dreman's fee will be reduced proportionately, provided that in no event
         will such fee be reduced below .35% on the first $50 million of the
         Fund's average daily net assets. Since June 1, 1996, all the assets of

         1997. The Distributor paid commissions to salespersons and from these
         fees, incurred other distribution costs.
 
         Pursuant to a plan adopted in accordance with Rule 12b-1 of the
         Investment Company Act of 1940, as amended, the Fund is authorized to
         pay the Distributor a fee pursuant to the Class A Distribution Plan of
         up to 0.35% of average daily net assets for the services it provides in
         connection with the promotion and distribution of Fund shares. However,
         at the present time the Board of Trustees has authorized payments of
         only .25% of average daily net assets. Under the Class C Distribution
         Plan the Fund may pay the Distributor a fee equal to 1.00% of the
         average daily net assets. Such fees are accrued daily and payable
         monthly. During the six month period ended April 30, 1997, $21,206 and
         $56,624 were paid for distribution fees for Class A Shares and Class C
         Shares, respectively. The Manager and the Distributor are all wholly
         owned subsidiaries of Raymond James Financial, Inc.
 
       The Manager also is the Dividend Paying and Shareholder Servicing Agent

       the Manager for such expenses as of April 30, 1997 was $9,400, $4,400,
       $29,200 and $6,800, respectively. In addition, the Manager performs Fund
       Accounting services for the Growth Equity Fund, the Small Cap Stock Fund
       and the Value Equity Fund and charged $14,277, $19,237, and $14,687,

        EAGLE INTERNATIONAL EQUITY PORTFOLIO:
        ------------------------------------
        The Fund may enter into forward foreign currency contracts ("forward
        contracts") to facilitate settlement of foreign currency denominated
        portfolio transactions or to manage its foreign currency exposure or to
        sell for a fixed amount of U.S. dollars or other currency, the amount of
        foreign currency approximating the value of some or all of its holdings
        denominated in such foreign currency or an amount of foreign currency
        other than the currency in which the securities to be hedged are
        denominated approximating the value of some or all of its holdings to be
        hedged. Additionally, when the Subadviser anticipates purchasing
        securities at some time in the future, the Fund may enter into a forward
        contract to purchase an amount of currency equal to some or all of the
        value of the anticipated purchase for a fixed amount of U.S. dollars or
        other currency.
 
        At October 31, 1996, the Fund had outstanding forward foreign currency
        exchange contracts ("forward contracts") in order to hedge against
        changes in future foreign exchange rates and enhance return. Forward
        contracts involve elements of market risk in excess of the amount
        reflected in the Statement of Assets and Liabilities. The Fund bears the
        risk of an unfavorable change in the foreign exchange rate underlying
        the forward contract. Risks may also arise upon entering into these
        contracts from the potential inability of these parties to meet the
        terms of their contracts.
