Phyllodes 8–12 (–14) per whorl, straight or recurved towards apex, slightly flattened, 6–10 mm long, less than 1 mm wide, shortly mucronate, shortly puberulous.with an obscure impressed nerve on upper surface, both surfaces obscurely ribbed when dry. Peduncles 10–25 mm long, sparsely pilose, viscid. Heads 25–40-flowered. Flowers 5-merous; calyx 0.8–1.2 mm long, lobed to c. half way, membranous, glabrous, the lobes spathulate or triangular; corolla lobes smooth, glabrous or sparsely hairy. Pods linear, curved, 20–40 mm long, 6–8 mm wide, with nerve-like margins, coriaceous, viscid. Seeds transverse, 3.5–4 mm long; pleurogram open.
Occurs commonly in the Pilbara region and at scattered localities E to the Rawlinson Ra., W.A., in the Macdonnell and Musgrave Ranges, N.T. and E to Dajarra, Qld. Grows in shallow, sandy or rocky soil.
Phyllodes sometimes to 14 per whorl, usually bright to dark green and aromatic with a curry-like scent. Often confused with A. perryi which has larger phyllodes and stipules, as well as striate-nerved corollas. The smooth corolla suggests relationships with A. hippuroides .
