Description.

Shrub 1-2 m tall. Leaves: petiole 2.2- 4 cm long; rachis 4-9 cm long, grooved above and with occasional scattered dark glands; pinnae (3-)5-10(-12) pairs per leaf, (2.8-)3.5-6(7) cm long, with 20-40 pairs of leaflets; leaflets 5-10 × 0.9-1.5 mm, linear to linear-oblong, apex rounded to acute, base oblique, mid-rib running from distal corner of leaflet base to apex centre, lamina glabrous. Inflorescence: a spiciform raceme, 4-5.5 cm long, solitary or aggregated in fascicles or on short lateral shoots, rachis glabrous. Flowers: yellowish-white; pedicels 1.5-2 mm long, articulated near or below the middle, with minute reddish glands at the base; calyx 0.75-1.25 mm long, toothed, glabrous; petals 2-3 mm long; stamen filaments 4-5 mm long. Fruit: a laterally compressed, straight to slightly curved craspedium, 12-18 × 2-3.2 cm, lacking transverse septa between seeds, thus leaving the valves to separate from the replum intact upon ripening, the epicarp exfoliating from the endocarp. Seeds: laterally compressed, 15 × 13 × 3.5 mm.
