Staminate flowers with stamens 5, the filaments free, shorter than the introrsely dehiscing anthers; pollen grains oblate, 3-5-colporate, echinate; pistillode conspicu-ous. Pistillate flowers with 3 carpels, the ovules 2 in each locule, anatropous, the styles connate, the stigmas thick, bifid, reflexed. Fruits capsular, massive, the endo-carp often very thick, tardily dehiscent, the columella massive, tapering from the base; seeds usually 3 per capsule, ovoid or ellipsoid, smooth, not carunculate, thin-walled, the endosperm scanty or absent, the massive angled cotyledons filling most of the seed, the radicle short.
