New shoots white to grey, sometimes with golden tips. Phyllodes terete to compressed, occasionally flat and linear, straight to slightly curved, (1–) 2–7 (–10) cm long, 0.8–1.5 mm wide, with an acute to acuminate and commonly uncinate apex, ±rigid, glabrous, with 8–20 fine nerves in all, 3-to many-nerved per face when flat. Inflorescences simple, 1 or 2 per axil; peduncles 0–2 mm long, glabrous to puberulous; receptacle puberulous; heads loosely obloid to cylindrical, 8–15 mm long, golden; bracteoles shortly stipitate, broadly fan-shaped. Flowers 4-merous; sepals ½–¾-united; ovary hairy. Pods linear, strongly raised over and constricted between seeds, to 8 cm long, 3–4 mm wide, thin-crustaceous, glabrous. Seeds longitudinal, elliptic, 3–4 mm long, dull to subnitid, smooth, pitted and/or verruculose, black; aril apical.
