Stamens 4 or 6, inserted at base of perianth lobes; filaments narrow, basifixed or epipeltate; anthers 2-locular, introrse to latrorse, dehiscing by longitudinal slits. Ovary inferior, usually 3-locular; ovules few–several per loculus, placentation axile; style short, 3-branched.

Fruit usually a capsule and mostly crowned by persistent remains of perianth, rarely fleshy and indehiscent; seeds with hard, shiny or dull, thick black or brown testa.
