Pods dehiscent, conspicuously densely pubescent. (from Flora of Zimbabwe website) Shrub or tree to 10 m high; trunk to 0,35 m in diam.; branches usually ascending. Bark pale to dark greyish-brown or brown, rough; young branchlets grey- or reddish-brown, densely puberulous to pubescent, frequently with minute reddish glands scattered in amongst the pubescence. Stipules not spinescent, in pairs, linear, l,8-3,8x 0,2-0,7 mm, soon deciduous. Prickles in pairs just below the nodes, usually strongly recurved, sometimes straightish, often broad-based, up to 8 mm long. Leaves: petiole 0,3-1,3(2,2) cm long, adaxial gland usually present, variable in position, slightly raised or occasionally stalked, 0,4-1,1 x 0,1-0,4 mm; rhachis 1,7-6(10) cm long, puberulous to densely pubescent, abaxial surface often with scattered recurved prickles up to 2 mm long, with a gland at the junction of the top 1-3(7) pinnae pairs and occasionally between the lowest 1-3 pairs; pinnae 8-14(26) pairs; rhachillae (0,5)1-2,4(3,4) cm long, puberulous to densely pubescent; leaflets grey-green, (16)20-36(48) pairs per pinna, 1-4 x (0,25)0,5-1,1 mm, linear to linear-oblong, apex rounded to subacute, glabrous or sparingly to densely appressed-pubescent below, margins with or without spreading cilia. Inflorescences spicate, solitary, fascicled or crowded into an irregular terminal panicle. Flowers yellowish-white, sessile; spikes (2,2)3-7,4(8,6) cm long; peduncles 0,3-2,8 cm long, puberulous to densely pubescent, often glandular. Calyx densely puberulous to pubescent, tube 1-2 mm long, lobes 0,4-1,1 mm long. Corolla subglabrous or appressed-pubescent especially towards the apices of the lobes, tube up to 3,4 mm long, lobes up to 1,1 mm long. Stamen-filaments free, up to 7,5 mm long; anthers ± 0,15 mm across, with a deciduous apical gland. Ovary 0,7-1,5 mm long, glabrous, shortly stipitate. Pods olive- to reddish-brown or brown, (5)6-11(14) x (0,9)1,2-2,3 cm, straight, acute to distinctly acuminate apically, longitudinally dehiscent, margins entire or frequently irregularly constricted between the seeds, umbonate over the seeds, coriaceous, puberulous to densely pubescent, with numerous minute scattered reddish-brown glands.
