Dense, domed or obconic shrubs 0.3–1.5 m high. Branchlets tomentulose. Stipules persistent, ± subulate, to 2 mm long. Phyllodes spreading, linear to linear-oblanceolate, straight to shallowly incurved, 2–4.5 cm long, 1–4 mm wide, obliquely mucronate to subuncinate with a hard innocuous to coarsely pungent point, rarely with a straight sharply pungent point, rigid, glabrous except pulvinus tomentulose, with ± 9 plane or slightly impressed close veins per face (20 veins in all) with very occasional anastomoses; intervein spaces with strongly raised stomata; glands 1 or 2. Inflorescences simple, 2 per axil; peduncles 1–1.5 mm long, glabrous; basal bracts cucullate, rostrate; heads globular, 3–3.5 mm diam., 18–20-flowered, golden. Flowers 5-merous; sepals free or to 1/2-united. Pods linear, strongly undulate, 1–4 cm long, 2.5 mm wide, crustaceous, papillous; marginal vein distinct, much paler.
