Shrub or tree to 5 m high, single-stemmed, pruinose. Bark smooth, brown. Branchlets flattened, 0.5–1 cm wide, tawny yellow or brown, pruinose, glabrous, bearing wings 0.8–2.5 mm wide, formed by decurrencies with phyllodes (lower edge of phyllode usually continuous with branchlet). Phyllodes obliquely narrowly lanceolate to ovate or elliptic, usually 6.5–13 cm long, 14–45 mm wide, with convex upper margin, thin to subcoriaceous, glabrous, with 3–5 conspicuous longitudinal veins (the pair closest to lower concave or straight margin confluent to 2 cm above base, the other veins separate to the base but not reaching apex); minor veins anastomosing, 2 or 3 per mm; gland 1, basal, to 3 mm above pulvinus. Spikes usually 1.6–2.7 cm long, golden. Flowers 5-merous; calyx 0.2–0.5 mm long, truncate or dissected to ¼ of length, glabrous; corolla 1.8–2.5 mm long, glabrous, with free petals; ovary glabrous. Pods linear, straight-sided, straight or slightly falcate, flat or slightly twisted, 4–11 cm long, 2–4.5 mm wide, glabrous; margins pale, prominent. Seeds longitudinal, oblong-elliptic, 2.2–4.7 mm long, brown; areole open.
Grows often on sandstone plateaux with laterite gravel, on cliffs near the ocean, along watercourses in gullies or in crevices amongst boulders, sometimes on basalt or quartzite, in sandy, stony, often alluvial soils, in mixed shrubland.
Can be grown by cuttings or seedlings. Seeds needs soaking.
