Shrub 2–3 m tall; crown spreading and umbrella-like. Branchlets glabrous. Phyllodes narrowly elliptic, falcately recurved, 6–14 cm long, 5–12 mm wide, to 25 mm wide at base of branches, acuminate, glabrous, ±scurfy with age, 1-nerved per face; lateral nerves few and obscure; glands sometimes 2, with the lowermost normally 2–6 mm above pulvinus. Inflorescences usually racemose; raceme axes mostly 2–4 cm long, glabrous; peduncles usually 6–15 mm long, to 25 mm in fruit, glabrous; heads globular, 8 mm diam. at anthesis, densely 40–60-flowered, pale yellow. Flowers 5-merous; sepals united almost to apex. Pods rounded on opposite sides over alternate seeds, to 25 cm long, 12–17 mm wide, thickly coriaceous to subwoody, glabrous. Seeds longitudinal, broadly elliptic, 6.5–7.5 mm long, slightly shiny, black; funicle encircling seed in a double fold, thick, red-brown to black; aril clavate.
