Trees or shrubs, usually evergreen. Leaves opposite, simple, petiolate; leaf blade entire. Inflorescences axillary or rarely terminal panicles, sometimes cymes, umbels, heads, racemes, or fascicles. Flowers bisexual. Calyx small, 4-toothed or 4-lobed. Corolla white or yellow, 4-parted; lobes almost free to base or united into a very short tube or joined in pairs at base, valvate in bud. Stamens 2, inserted at base of corolla lobes; anthers elliptic or long elliptic, subextrorse. Ovules 2 in each locule, pendulous. Style short; stigma entire or 2-cleft. Fruit a drupe; endocarp bony. Seeds usually 1; endosperm fleshy or absent; radicle upward.
