Moderate-sized tree, the branchlets glabrous and markedly lenticellate. Leaves moderate-sized, usually 4-(or sometimes 6-, or reported occasionally 2-) foliolate; petiole 1-2 cm. long, terete except angled laterally above, glabrous; rachis 2-5 cm. long, glabrous, wingless but ridged and somewhat marginate laterally above, bear-ing a small, sessile, disc-like or subcupuliform gland between insertion of the pepiolules; leaflets usually 2 pairs, sometimes 3 or 1? pair, mostly oblong or elliptic, 4-12 cm. long and 1.5-5.5 cm. wide, usually acute and bluntly acuminate apically, cuneate and slightly inequilateral basally, glabrous above and below; stipules linear-oblong, up to 5 or 6 mm. long, pubescent, subpersistent or caducous. Inflorescence of 1 or 2 elongate spikes from each of a number of foliate or defoliate axils; spikes subglabrous, about 10 cm. long, the peduncular portion only about 2 cm. long, the many flowers scattered over the remaining floriferous portion. Flowers whitish, glabrous to puberulent; calyx cupuliform-tubular, 1-2 mm. long, the teeth minute but distinct; corolla usually 4-5 mm. long, narrowed basally, expanded apically, subglabrous; stamens 12-15 mm. long, fused basally into a tube greatly and notice-ably exceeding the corolla (Panama?) or only slightly exceeding the corolla. Legume reported flat and strongly compressed, 7-15 cm. long and 2-3.5 cm. wide, subglabrous, the margins thickened.

A tree. It grows 9-20 m tall. It has a low crown. The trunk is 50-70 cm across. The leaves are compound and have 2-3 pairs of leaflets. The end pair of leaflets are 6-13 cm long and the pair at the base are 3-8 cm long. The flowering groups are in the axils of leaves with 1-3 groups of flowers. The flower is like a short bottlebrush of white thread like stamens. The fruit is a curved pod 5-20 cm long. There are 5-15 seeds in a sweet aril.
Tree to c. 15 m high. Flowers in spikes, white. Pod brown, oblong flat, up to 15 by 3.5 cm, with the seeds embedded in a sugary pulp.
Moist lowland limestone areas. Wet to semi-dry forests, or highland savannas. Found in a variety of habitats from dry scrublands in some Caribbean islands to the rain forest or the wet cloudy forests of Central American highlands.
