Dioecious trees, the branches unarmed. Leaves alternate, distichous; stipules lateral. Both staminate and pistillate inflorescences racemes and spikes; the small, congested or relatively distant flowers interspersed with small, shortly stipitate, peltate bracts. Staminate flowers: tepals 4, united or essentially free to the base, imbricate in bud, without an obvious pistillode; stamens 4, the filaments about as long as the tepals and scarcely inflexed before anthesis, the anthers broadly oval, extrorse. Pistillate flowers hypogynous to perigynous: tepals 4, completely united or minutely 4-lobed; ovary superior to inferior, the style central and deeply bifid. Fruit a small 1-seeded drupe.
