Flowers unisexual, mostly solitary and axillary to leaves on lateral and terminal branchlets or rarely aggregated on branches, pedicellate, hypogynous, actinomorphic; pedicels with minute bracteoles; perianth of 5-17 tepals, the outermost green abaxially, more showy inward and adaxially. Staminate flowers with many stamens, variously aggregated; anthers 4-sporangiate, the 2 thecae lateral, dehiscing longitudinally; filaments short, basally fused to a cylindrical to globose torus, the connective slightly swollen and broaden, pollen usually 6-colpate with 3 colpi converging at the distal pole. Pistillate flowers with many subascending carpels, the carpels 1-loculed, narrowed basally and fused to a cylindrical to globose torus; style short, the stigma papillate; ovary ovoid to obovoid; ovules 2-5, anatropus; fruits sessile, baccate, on a globose or elongate torus; seeds 1-5, laterally flattened, reniform or ovoid, the testa smooth or rugulate, the endosperm copious, oily, the embryo small.
