A large tree from 50–150 ft. in height, wholly glabrous; the extremities marked with annular scars, apparently of broad-based caducous stipules. Leaves abruptly pinnate, varying from 4 or 6 in. to 1 1/2 ft.; leaflets in 5–8 pairs, coriaceous and shining above, ovate-elliptical to ovate-lanceolate or oblong obtusely apiculate or shortly acuminate, base usually broadly and very obliquely rounded, reticulation rather prominent, more or less distinctly translucent-punctate; 2–7 in. long; petiolule 2–5 lines. Flowers white or tinged with violet, in terminal many-flowered glabrous often glaucous panicles consisting of numerous alternate racemes successively spreading or decurved from a common axis. Bracts very early caducous, obovate or oblong, 1/4– 1/3 in. long; bracteoles geminate, elliptical or obovate, thinly coriaceous, 1/3 in. long, falling long before expansion. Calyx-tube narrowly funnel-shaped, narrowed into the pedicel of 1/6– 1/2 in., segments obovate- or oval-oblong 1/2 in. long. Posterior petal only usually noticeable at flowering, oblong, entire, dotted with immersed glands, shorter than the calyx-lobes. Filaments filiform, glabrous, exserted. Ovary glabrous on a gynophore of about its own length, narrowed above into the style. Legume usually 1-seeded, obliquely obovate, the ventral suture much rounded, dorsal nearly straight, 2–2 1/2 in. long, 1–1 1/2 in. broad. Seed compressed, dark-coloured, 3/4 in. long, 1/2– 2/3 in. broad; funiculus 1/4– 1/2 in.
