Trees, deciduous; trunk swollen and/or buttressed, trunk and branches usually spiny. Petiole long; leaf blade palmately compound; leaflets 3-5(-9), shortly petiolulate, both surfaces glabrous, abaxially gray-white, base attenuate, margin serrate or entire. Flowers blooming before or simultaneously with leaf flush, solitary or 2-15-fascicled, pendulous, axillary or subterminal, actinomorphic, rarely zygomorphic. Calyx campanulate, truncate or irregularly 3-5(-12)-lobed, thickly fleshy, persistent. Petals 5, pink or yellow-white, connate at base and coherent to staminal tube, falling with stamens and style. Stamens (3-)5-15; filament tube short, sometimes thickened or with sterile appendages, free parts of filament long to absent, each bearing 2(or 3) straight to strongly twisted thecae. Ovary syncarpous, 5-locular; ovules many per cell; style filiform; stigma capitate to lobulate. Capsule oblong or nearly obovate, pendulous, woody or leathery, loculicidally dehiscent into 5(or 6) valves, inner walls densely woolly. Seeds many, enclosed in wool.
Trees, often spiny. Leaves digitately compound, with caducous stipules. Flowers axillary or subterminal, solitary or fasciculate. Calyx cupular, truncate or 3-5-lobed. Petals 5, imbricate, connate at the base to the staminal tube. Stamens (10-)15, in 5 bundles, united near the base into a filament-tube; each phalange of 3 connate filaments bearing 2-3 straight or coiled anther-thecae, each bundle alternipetalous. Ovary 5-locular, each locule with many ovules; stigma club-shaped, pentagonal. Capsule a woody or coriaceous 5-valved capsule. Seeds many, surrounded by the wool of the endocarp; endosperm thin or absent; cotyledons much contorted.
