Dense, intricate, low-domed, semi-prostrate, spreading shrub 0.3–1 m high, to 3 m across. Branches grey, glabrous,; branchlets numerous, short, straight, rigid, divaricate, spinescent, often devoid of phyllodes. Phyllodes asymmetric, arcuate-oblong or widely elliptic, with upper margin straight to shallowly concave and lower margin markedly convex, some reflexed, 3.5–7 mm long, 1.5–2.5 mm wide, obtuse, excentrically mucronate with upturned mucro, subglaucous, glabrous; midrib slightly raised; lateral nerves ascending and anastomosing near margins. Inflorescences simple or sometimes a rudimentary 1-headed raceme inserted with vegetative bud on a common axis greater than 0.5 mm long; peduncles 3–4 mm long, glabrous or antrorsely appressed-puberulous; heads obloid to shortly cylindrical, 6–8 mm long, 4–5 mm diam., presumably golden. Flowers 5-merous; sepals ½–¾-united. Pods tightly coiled as in Medicago , to 7 mm long (unexpanded), with valves 3 mm wide, firmly chartaceous, glabrous. Seeds longitudinal, oblong-elliptic to ovoid, 3 mm long, dull, dark brown; aril minute, subterminal.
