Shrub or tree usually 3–8 m high; branches slender and spreading or arching gracefully. Branchlets ribbed, glabrous or hirsutellous. Phyllodes crowded, on short stem-projections, markedly inequilateral, generally obdeltate with adaxial margin conspicuously rounded with the proximal edge ± parallel to branchlet, usually 7–12 mm long and 5–14 mm wide, mucronate, green to grey-green, glabrous, imperfectly 2-veined; midrib near abaxial margin and a lesser vein above it; lateral veins indistinct; gland prominent, 3–7 mm above base, sometimes similar to A. kettlewelliae. Inflorescences prolific, racemose; raceme axes longer than phyllodes, glabrous or hirsutellous; peduncles 2–4 mm long, slender, glabrous; heads globular, 6–9-flowered, golden. Flowers 5-merous; sepals united. Pods narrowly oblong, to c. 8 cm long, 6–9 mm wide, firmly chartaceous, glabrous. Seeds longitudinal, oblong to ovate, 3.5–5 mm long, dull, black; aril clavate.
A widely cultivated ornamental species with prolific racemes at ends of branchlets. A prostrate variant 'Golden Carpet' and a dwarf variant (c. 0.5 m high) are known in cultivation but should be propagated from cuttings to retain their respective growth habits, fide W.R. Elliot & D.L. Jones, Encycl. Austral. Pl. 2: 99 (1982).
Can be grown by cuttings or seedlings. Seeds needs soaking.
