Description

Erect or straggling shrub, 1–2.4 m high. Bark smooth. Branchlets angled apically, clothed with short stiff hairs to 0.2 mm long, with prevalent lenticels; phyllode bases persistent. Bipinnate leaves sometimes present. Phyllodes crowded, erect or retrorse, linear, subterete to ±flattened, (1–) 2–5 (–6.5) cm long, 0.4–1.2 mm wide, with curved mucro (0.2–0.5 mm long), glabrous or almost so; midrib obscure; gland not prominent, 0.5–7 mm above the slightly hairy pulvinus. Inflorescences racemose; raceme axes (0.3–) 1.5–3 (–7) cm long, puberulous to glabrous; peduncles 2–4.5 mm long, puberulous to glabrous; heads globular, 4–8-flowered, yellow to dark yellow. Flowers 5-merous; calyx membranous, dissected to 1/4–2/5, with broadly deltate lobes and tube slightly hairy. Legumes narrowly oblong, scarcely constricted between seeds, flat, to 8.5 cm long, 4–7 mm wide, firmly chartaceous, light brown, smooth. Seeds longitudinal, black; areole narrowly elliptic-oblong.

Notes

This species appears to rarely set seed, but reproduces by underground runners. It is closely allied to A. boormanii which is distinguished most readily by its habit (bushy shrub to 5 m high), clearly flattened, normally wider phyllodes and glabrous branchlets.
