Shrubs or dwarf trees, monoecious, evergreen, glabrous. Leaves opposite, sessile or subsessile, entire, penninerved, coriaceous. Inflorescences axillary spikes, short, dense-flowered; bracts often numerous, like sepals but smaller; flowers solitary in each bract, sessile or pedicellate, the terminal one often female, the remainder male. Male flowers: sepals 4 - 6, 2-seriate, imbricate, unequal; stamens 4 - 6, opposite to sepals; filaments inserted on receptacle around the pistillode, free, exserted; anthers dorsifixed near the base, oblong at length, recurved; connective thick;anther-thecae introrse, parallel, opening by longitudinal slits; pistillode truncate or 3-lobed, rarely absent. Female flowers: sepals 4 - 6, 2-seriate, imbricate, outer ones smaller; ovary tricarpellary, 3-locular; ovules 2 in each locule, pendulous from outer angle of the locule; styles 3, short, thick, distant or rarely contiguous at the base. Fruits capsular, ovoid, 3-horned at apex formed by the persistent styles, coriaceous, loculicidally dehiscent into 3, 2-seeded and 2- horned valves; seeds oblong, somewhat 3-sided, carunculate; testa shiny black; endosperm rather fleshy; cotyledons oblong.
