Synonym Feuilleea Ktze. Rev. Gen. P1. 1:182. 1891, in part.
Description Unarmed trees, usually large, the branchlets pubescent or glabrous. Leaves bipinnate, moderate or large, 2- or few-ranked; petiole prominent, bearing a gland usually near the middle; pinnae few to many, opposite, the rachis bearing glands especially terminally; leaflets usually numerous and small, inequilateral; stipules inconspicuous, caducous. Inflorescence of solitary to fasciculate pedunculate heads, axillary, or paniculate by insertion at defoliate nodes; peduncles slender; heads small, globular; flowers condensed, sessile, small; bracts small and inconspicuous. Flowers whitish; calyx campanulate to tubular-funnelform, valvate, briefly 5- dentate; corolla more or less funnelform, 5-lobed, valvate, about double the calyx; stamens 10 to many, exceeding the corolla, united below into a short, included staminal tube; anthers small, eglandular, quadrangular; ovary sessile, several- ovulate; style slender, equalling or exceeding the stamens, the stigma small. Legume diagnostic, circinnate or reniform, coiled into a complete or nearly complete circle, compressed or almost flattened but nevertheless somewhat fleshy, usually glabrous and lustrous, fairly broad, ligneous, indehiscent, septate between the seeds, the seeds transverse.
Habit trees
Distribution Mexico to Argentina. Introduced into Pacific Islands and elsewhere.
Note This small American genus (8 or less species, mostly South American) is re- tained separate from Pithecolobium (and Albizzia) following traditional practice. Nearly all students of the group have realized that Enterolobium probably consti- tutes no more than a section of Pithecolobium (in the broader sense), but for con- venience have retained the genera separate. Morphologically the distinctiveness of Enteralobium rests mostly with the unusual, coiled legume.
