Straight-boled, monopodial tree, up to 33 m high; bole to c. 20 m, 150 cm in diameter. Branchlets ridged, with reddish brown lenticels and very prominent leaf-scars, sparsely rusty puberulous. Stipules to c. 2.5 mm, erect when young, soon recurved and thorn-like, often caducous. Leaves: rachis 9-38 cm, sulcate, tomentose or glabrous, with gland(s) c. 1-1.5 cm above the base and below the junctions of the distal pairs of pinnae, circular to elliptic, usually raised, cushion-shaped or flat, 1-4 mm long, distal glands smaller; pinnae 5-13 pairs, 5-12 cm, tomentose, with gland(s) just below the junctions of the 1-4 distal pairs of leaflets; circular with slightly raised margins, c. 0.3 mm in diameter; leaflets 9-18 pairs per pinna, opposite, sessile, subcoriaceous, elliptic-oblong, unequal-sided, 0.8-2.3 by 0.3-1 cm, base asymmetrically truncate to half truncate/half cuneate, apex rounded, mucronate; both surfaces glabrous; main vein distant by c. 3/8 of the width of the leaflet from the front margin. Inflorescences composed of pedunculate corymbs aggregated into terminal or axillary panicles, puberulous or sometimes glabrescent; peduncles in umbels of 4 or 5, 2-3.5 cm, bearing corymbs consisting of 20-25 pedicellate flowers. Flowers dimorphic, pentamerous, bisexual. Calyx green, funnel-shaped to narrowly campanulate, sericeous, (3-)4(-5) mm; teeth triangular, acute, c. 0.3 mm. Corolla whitish, funnel-shaped, sericeous, 6-8 mm; lobes elliptic-ovate to triangular-ovate, acute, 2-3 mm. Stamens greenish, especially towards the top, c. 20-25 mm, tube to c. 3.5 mm, shorter than the corolla-tube. Ovary sessile, glabrous, 3.5-4 mm. Pod golden yellow, oblong-linear, straight, strongly flattened, c. 6-30 by 4-5 cm, indehiscent, but valves breaking up irregularly; valves thinly char-taceous-membranous, glabrous, veins inconspicuous, reticulation visible over the seeds only. Seeds yellow, ovate, strongly flattened, c. 11 by 7.5 by 1 mm, narrowed at the hilum; areole elliptic(-obo-vate), pleurogram not parallel to the margin of the seed, open towards the hilum.
Can be grown by seedlings. Seeds needs soaking.
