Trees to 10 m, crown rounded. Stems pilosulous to glabrescent, bark light tan, fissured in rectangular plate, with conspicuous pale lenticels on young branches.

Legumes sessile, ochre-brown, 1.2–18.6(–25) × 3.7–6 cm (including beak), margins straight to slightly constricted between seeds, base rounded, apex acute, with 10 mm beak, glabrescent, usually dehiscent along 1 suture, valves undulating, raised over seeds. Seeds 4–11, 7–8(–12) × 7–9 mm. 2n = 26.

Discussion
Albizia lebbeck is widely cultivated as an ornamental and shade tree; it is naturalized in the subtropics and tropics and is abundant in central and southern Florida. The rattling pods are persistent during the winter while the trees are leafless (D. Isely 1998).
