Dioecious or hermaphrodiate trees (one sp. scandent), sometimes with plank buttresses; bark smooth or rough due to scales or raised lenticels, relatively thin and shed in irregular plates; resin clear or somewhat milky. Stellate hairs sometimes present. Leaves evergreen, exstipulate; pulvinuli usually apparent on terminal and lateral petiolules; leaflet margin entire; intersecondary veins usually present,.  Inflorescences axillary or sometimes (pseudo-)terminal.  Flowers unisexual or less often bisexual; perianth 3-parted, calyx (shallowly) cupular to urceolate, truncate or 3-lobed, sometimes divided nearly to base; petals distinct, valvate at apex, on sides valvate (American species) or slightly imbricate, with an inflexed apiculum; stamens in two subequal series, inserted at base of disk or on the side or rim; anthers continuous with the filaments or sagittate; pistillode either reduced but provided with locules and ovules, or a variously shaped parenchymatous structure, or fused with the disk to form an ovariodisk; otherwise disk annular; pistil 2—3-locular; style short and thick, stigma 2—3-lobed.  Fruit an indehiscent, compound drupe, oblique-)ovoid to ellipsoid, rarely globose, exocarp thin and drying wrinkled; mesocarp thin and oily-resinous; endocarp (thinly) cartilaginous, smooth, not lobed; pyrenes 1(2)-seeded, the 1–2 aborted locules strongly compressed, forming an articulated, separable plate on periphery of pyrene. Testa smooth, cotyledons palmate or up to 13-palmatifid; folded or contortuplicate.  Germination usually epigeal and phanerocotylar, rarely hypogeal and cryptocotylar, the first eophylls opposite or alternate and simple or trifoliate.

About 70 species in the moist tropics, usually lowland but some montane.
