Shrub 0.4–2 m high, slender, glabrous, resinous. Bark longitudinally fissured, grey or greyish brown. Branchlets ± flattened towards apices, often pruinose, glabrous; ridges prominent, non-resinous. Phyllodes obliquely narrowly elliptic, elliptic-oblong or oblanceolate, often dimidiate, straight to subfalcate or rarely falcate, (5–) 6–10 (–12) cm long, 10–25 (–33) mm wide, with pale prominent margins, subcoriaceous, glabrous, with 3 prominent longitudinal veins (2 continuous from base to apex, 1 confluent with lower margin near base) and 3 or 4 subprominent parallel veins; minor veins 2–3 (–4) per mm, anastomosing; gland 1, basal, 0.2–3.8 mm above pulvinus. Peduncles usually (15–) 20–40 (–50) mm long. Spikes 0.9–2.5 cm long, bright yellow. Flowers 5 merous; calyx 0.5–0.8 mm long, dissected for ⅓–½ of length, glabrous; corolla 1.2–1.8 mm long, dissected for ⅓–½ of length, glabrous; ovary glabrous. Pods erect, mostly narrowly oblanceolate, straight-sided, ± flat, 3.8–8.5 cm long, (5–) 7–14 mm wide, ± woody, reddish-or purplish-brown, paler over seeds, sometimes pruinose, obliquely veined, glabrous, opening elastically from a hooked apex; seed partitions thick. Seeds oblique, elliptic to obovate, 4.6–6.6 mm long, brownish black; funicle-aril turbinate.
Grows on sandstone, in gravelly soils on stony hillsides, in open eucalypt woodland, usually near creeks, often with Melaleuca species.
