Inflorescences grouped toward the tip of the branchlets, axillary, fasciculate, or flowers solitary or geminate. Flotwers hermaphrodite, actinomorphous, sometimes subzygomorphous, with tufted hairs, pedicellate, bracteolate, the bractlets fugacious; receptacle eglandular; calyx campanulate to more or less tubiform, truncate or irregularly lobed, persistent or accrescent; petals 5, adnate to the base of the staminal column, fleshy; stamens 5, the staminal column conical or the lower part cylindric and thickened and the upper part conical, sometimes provided with one whorl of staminodia, the filaments bearing each 1-3 linear to anfractuose anthers; anthers 1- to 2(-4)-thecate, longi- tudinally dehiscent; pollen colporate, the sexine reticulate; ovary superior to sub- inferior, sessile, 5-celled, the cells many-ovulate; style filiform or dilated upward; stigma capitate or 5-lobulate. Capsules coriaceous to ligneous, loculicidally 5- valvate, the central columella winged and persistent; seeds numerous, obovoid or subglobose, imbedded in copious kapok; cotyledons epigeal and expanded above the ground level, opposite, petiolate, folded and foliaceous.
