It is a deciduous tree up to {{convert|80|ft|m|abbr=off|sp=us}} in height which grows in semideciduous rainforest with a definite dry season. It is found from Nicaragua to Brazil. Its flowers are cream-colored and like those of Ceiba spp., in forming a roundish cluster of stamens on a stalk surrounding the pistel, in this instance up to one thousand stamens in number.{{cite journal| last= Standley | first= Paul C. | date= 1933 | title= Flora of Barro Colorado Island |journal= Contributions of the Arnold Arboretum | volume= 5 | issue= 1 | page= 103}} The leaves generally have seven smooth-edged narrowly oblong leaflets.
