Androecial members indefinite in number. Androecium 100. Androecial members free of the perianth; markedly unequal; free of one another; to 15 -whorled. Androecium exclusively of fertile stamens, or including staminodes. Staminodes 50. Stamens 100; attached on the rim of the hypanthium; all more or less similar in shape; polystemonous; alternisepalous, or oppositisepalous; both opposite and alternating with the corolla members; inflexed in bud. Filaments not geniculate; hairy, or glabrous; filiform, or strap-shaped. Anthers all alike; dorsifixed, or basifixed; versatile; dehiscing via longitudinal slits; tetrasporangiate. Gynoecium 2–100 carpelled. Carpels increased in number relative to the perianth. Gynoecium apocarpous; eu-apocarpous; superior. Carpel stylate; apically stigmatic. Style straight. Carpel 2 ovuled. Placentation apical. Gynoecium transverse. Styles simple; not becoming exserted; persistent, or deciduous; hairy, or hairless. Styles straight in bud. Stigmas clavate, or capitate (or discoid or 2-lobed). Ovules funicled; pendulous; collateral, or superposed; non-arillate; anatropous.
Fruit and seed features. Fruit 9–26 mm long; falling from the plant before the next growing season; fleshy; yellow, or red, or black; hairy, or not hairy; an aggregate. The fruiting carpel indehiscent; drupaceous. Fruit 1 celled. Endocarp ribbed (but rugose or lacunose). Dispersal unit the fruit.
