Description Armed or unarmed trees, shrubs or perhaps vines, autotrophic or reportedly hemiparasitic. Leaves alternate, sometimes opposite, simple, generally entire, pin- nately veined, petiolate; estipulate. Inflorescences axillary, panicles, racemes, cymes or umbels, often fasciculate. Flowers dichlamydeous, bisexual or rarely polygamodioecious, sometimes polymorphic, actinomorphic, generally small and inconspicuous. Calyx small, gamosepalous, crateriform to campanulate, usually with a 3- to 6-toothed margin, free or basally adnate to the ovary or to the disc, sometimes accrescent. Petals 3-6, usually the same number as calyx lobes, free or connate, valvate or imbricate in bud. Disc sometimes present, simple or cupuli- form. Stamens generally the same number as, or twice the number of, petals, the anthers dehiscing longitudinally or by valves. Pistil 1, the ovary superior or rarely half-inferior, sessile, generally 2- to 5-loculate, the ovules the same number as locules, pendulous, integuments 0, 1 or 2, the style simple, sometimes hetero- morphic, terminal, elongate to obsolete, the stigma often 3-parted. Fruit mostly a drupe, sometimes accompanied by a colorful accrescent calyx.

Distribution A pantropic family of about 25 genera and 300 species. Four genera are known from Panama. A fifth genus, Chaunochitoin, is known from Costa Rica, Guiana and northern Brazil. Whether this disjunction is real or is an artifact of collection is not known at this time.
Key a. Calyx crateriform or cupuliform, free from the ovary, with 3 to 6 lobes or teeth; ovary superior; ovules with 1 or 2 integuments; fruit a drupe; plants root parasites (Ximenia) or autotrophes. b. Petals 5-6, free or connate, glabrous to more or less villous within; stamens 5-6 or 10-12; stigma 3- to 5-lobed; unarmed autotrophic shrubs or trees; leaves and bark with either resin canals or latici- ferous ducts or both. c. Leaves and bark with resin canals and laticiferous ducts; pubes- cence branched; calyx with 5-6 teeth, not accrescent; petals connate; ovary 3- or 4-loculate (by abortion from 5) .-------------------- 1. MINQUARTIA cc. Leaves and bark with laticiferous ducts but lacking resin canals; pubescence unbranched; calyx with 5-6 teeth or lobes, accrescent; petals free; ovary with 3 locules- ----------------------- 2. HEISTERIA bb. Petals 4-5, free, densely set with barbed hairs within; stamens 8-10; stigma minutely capitate; parasitic shrubs or trees, armed with axil- lary spines; leaves and bark lacking laticiferous ducts and resin canals ---------------------------------------------------------------------------------- 3.
