Albizia brevifolia Schinz

Shrub or tree 3-15 m high, trunk often branching near ground level into several to many ascending branches. Bark grey to grey-black, smooth or shallowly fissured; young branchlets very sparingly to ± densely appressed grey-puberulous when young, becoming glabrous with age; occasionally a few lateral shoots abbreviated and spinescent apically. Leaves sparingly to ± densely pubescent or glabrous: petiole 0.8-2.5 cm long, adaxial gland squat, sessile, ±0.25 mm high; rhachis (1)2.5-7(14) cm long; pinnae (3)6-10(15) pairs; rhachillae 1-4.4(6.5) cm long; leaflets 9-25 pairs, 3-7.5(9) x 0.75-1.75(2) mm, narrowly oblong to linear-oblong, symmetric, obtuse to subacute apically, not falcate, midrib nearly central (except basally), lateral nerves indistinct beneath, glabrous or margins ± appressed-ciliate. Inflorescences globose; peduncles 1.5-3 cm long, sparingly appressed-pubescent. Flowers white to creamy-yellow, on pedicels 1-1.5 mm long; bracteoles rapidly deciduous. Calyx 1-1.5 mm long, glabrous to ± puberulous outside. Corolla 4-5 mm long, tube 2.5-3 mm long, glabrous, lobes 1.5-2 mm long, pubescent apically. Stamens 1-1.8 cm long, united basally for ±3 mm, tube not or scarcely exserted beyond the corolla. Ovary ±1.5 mm long, shortly stipitate, glabrous. Pods (9)12-25 x (1.8)2.4-4.4 cm, linear to linear-oblong, valves thin, transversely venose, glabrous to finely puberulous, umbonate over the seeds, apparently indehiscent. Seeds 8-10 x ±6.5 mm, flattened.
