Bushy shrub or tree to c. 3 m high. Branchlets glabrous; cuticle often whitish. Phyllodes linear to narrowly oblanceolate, ± straight, (5–) 6–11 (–13) cm long, (1.5–) 2.5–7 (–9) mm wide, obtuse to acute, sometimes uncinate, glabrous, sometimes with whitish cuticle; midrib and lateral veins not prominent; glands 1 or 2, with lowermost 1–3.5 cm above pulvinus. Inflorescences 5–11-headed racemes; raceme axes (3–) 10–50 mm long, sparsely to densely appressed-puberulous with golden hairs, often glabrous in fruit; peduncles 2.5–5 mm long, with indumentum as on raceme axes; heads globular, 3.5–4 mm diam., 15–25-flowered, golden; bracteole laminae golden-fimbriolate. Flowers 5-merous; sepals united almost to apex in bud, often separating to base at anthesis. Pods to 17 cm long, 10–22 mm wide, firmly chartaceous to thinly coriaceous, glabrous. Seeds longitudinal, oblong-elliptic, 7–9 mm long, dull, dark brown; funicle ⅓–½ encircling seed, red-brown, brittle, readily detaching from aril.
Grows in clay and loam, often in low-lying areas, frequently in Eucalyptus salmonophloia woodland; often forming dense pure stands in disturbed sites.
