Shrub or tree 2–5 (–6.5) m high, occasionally 10–12 m, gnarled with sub-straight to crooked main stems. Bark fissured and fibrous, grey. Branchlets reddish, sometimes pruinose, glabrous. New shoots ferruginous by dense, microscopic hairs, soon glabrous. Phyllodes asymmetrically lanceolate to narrowly elliptic, with upper margin more convex than lower, straight to shallowly falcate, (8–) 10–14 (–18) cm long, (13–) 20–40 (–45) mm wide, sub-acute to obtuse, coriaceous, grey-green to glaucous, glabrous; multistriate by fine, close veins, few anastomosing; pulvinus (2–) 3–6 (–8) mm long, often reddish, smooth or finely wrinkled. Inflorescences normally binate racemes 5–15 mm long; peduncles 5–15 (–20) mm long, glabrous; spikes 25–45 mm long, densely flowered, light golden. Flowers 5-merous; calyx shortly dissected. Pods (few seen) narrowly oblong, 2–7 cm long, 7–10 mm wide, chartaceous, glabrous, yellowish. Seeds (few seen) longitudinal or transverse, ovate, 3.5–4 mm long, slightly shiny, brown; funicle flattened, creamy white; aril small.
