Flowers unisexual, the cymes terminal, pedunculate, reduced, of 1 or 2 pistillate and several staminate flowers; pedicels 1-3.5 cm long, pubescent; calyx rupturing into 2 or 3, valvate segments; petals 6-13, slender, 10-17 mm long, sericeous, longer than calyx, pinkish to dark red; staminate flowers with calyx persistent; disk with numerous segments; stamens numerous (60-150); filaments free; anthers apiculate; pistillate flowers with calyx deciduous; disk lobed; ovary densely sericeous; styles 3, thick, 1.5-2 mm long, reflexed, bifid.

Seasonal behavior uncertain. The fruits apparently mature in the dry season. Costa Rican collections show flowers mostly in the late dry season and early rainy season.
