Shrub to 3 m high, multistemmed, flat-topped, often decumbent. Bark corrugated towards base. Branchlets angular, dark purplish brown, glabrous, often resinous. Phyllodes linear, straight to shallowly curved, (5–) 8–22 cm long, 1.5–3.5 mm wide, coriaceous, glabrous, with 1–3 inconspicuous main veins; minor veins 7 or 8 per mm, fine, inconspicuous, parallel, not anastomosing. Peduncles 0.5–3.5 mm long. Spikes 0.3–1 cm long, golden. Flowers 5-merous; calyx 0.5–0.8 mm long, dissected to 1/5, with white hairs at base and brown hairs near apex; corolla 1.4–1.8 mm long, dissected to 1/2 with hairs as on calyx; ovary densely pubescent. Pods straight to slightly curved (often curving and twisting after open), slightly constricted between and raised over seeds, 2.5–8 cm long, 2–3 mm wide, thinly coriaceous to firmly chartaceous, longitudinally ridged, glabrous. Seeds longitudinal, narrowly elliptic-oblong, 3–4.5 mm long, black; pleurogram without halo; areole elongate, open.
Grows mostly in shallow sandy soil over granite at higher elevations, and on sandstone near the coast, in open eucalypt forests, occasionally in heaths or along creeks.
