Shrub 0.35-2 m high. Branchlets slightly angled, glabrous except minutely puberulous in phyllode-axils. Phyllodes linear to linear-oblanceolate, straight to slightly incurved, 2.5-4.5 cm long, 1.5-4 mm wide, acute to subobtuse, excentrically arcuate-mucronate, sometimes ±uncinate, semi-rigid, glabrous, obviously or obscurely 1-3-nerved per face. Inflorescences simple, 1 per axil; peduncles 0-0.5 mm long, puberulous; basal bracts semicircular, concave, thick; receptacle puberulous; heads obloid to short-cylindrical, 6-9 mm long, 4-4.5 mm diam., golden. Flowers 4-merous; sepals 1/2-2/3-united. Pods linear, strongly raised over and constricted between seeds, straight to slightly curved, to 6.5 cm long, 3.5 mm wide, crustaceous, longitudinally wrinkled, glabrous. Seeds longitudinal, broadly elliptic, c. 3 mm long, dull, black, surface alveolate-verruculose; aril apical, 2/3 as long as seed.
