Shrubs or small trees. Leaves spirally arranged, with colleters in the axils; usually drying black. Inflorescence of terminal panicles; flowers 5-merous. Sepals without colleters inside. Corolla lobes sinistrorse; mature corolla salverform, sometimes weakly infundibuliform at top of tube; lobes obovate; corona of short lobes perpendicular to the corolla tube, above and below stamens. Stamens completely included in corolla tube; ± sessile; connate to each other by appendages on the top of the anthers, not attached to gynoecium; anthers ovate, fertile entire length except for appendages. Disk absent. Gynoecium 2-carpellate, apocarpous but apically united into a common style, glabrous; several ovules per carpel; style filiform. Fruit a drupe; often only one carpel developing; exocarp fleshy, mesocarp fibrous, endocarp lignified; one seed per locule. Seeds flattened, ellipsoid.
Trees with latex. Branches stout. Leaves alternate, lateral veins 20-30 pairs, diverging almost at right angles to midvein. Cymes terminal, long pedunculate. Calyx deeply divided, without glands inside. Corolla white, funnelform, throat slightly dilated, ribbed, or with 5 pubescent scales; lobes broad, overlapping to left. Stamens inserted at corolla throat; anthers narrowly oblong, apiculate, free from pistil head, lobes rounded at base; disc absent. Ovaries 2, free, ovules 4 in each locule. Style filiform, dilated distally; pistil head shortly 2-cleft. Drupes 1 or 2, large, ellipsoid or globose, 1-or 2-loculed, with a thick, woody-fibrous endocarp. Seeds 1 or 2 per locule, wingless, not comose, without endosperm; cotyledons thin, radicle very short.
Shrubs or trees; white latex present in all parts. Leaves spirally arranged. Inflorescence terminal or in branching forks. Sepals free or nearly so, imbricate. Corolla with funnel-shaped tube and oblique lobes. Stamens included, anthers sessile. Pistil with apex at level of anthers; ovary of 2 separate carpels. Fruit of 2 (or by abortion 1) mostly separate drupaceous mericarps with hard endocarp. Seeds 1–2 in each mericarp, flat.
