Staminate flowers: stamens mostly (2) 3–6 (15), filaments free or connate; varying in pollen morphology; disc cut into segments; pistillode usually none. Pistillate flowers: sepals usually entire; styles free or united, bifid or variously divided or dilated; carpel usually 3-celled, ovules 2 in each cell; disc annular or cut into segments; pedicellate or subsessile. Fruits capsule or berry, globose or depressed globose, smooth or warty. Seeds trigonous, surface smooth or sculptured; seed coat dry and crustaceous.
