Shrub 0.3–1 m high. Branchlets yellow-ribbed, glabrous to sparsely antrorsely puberulous or shortly pilose. Phyllodes inequilateral, obtriangular to shallowly obtriangular with a prominent gland-bearing angle on adaxial margin, with adaxial proximal margin contiguous with branchlet, 4–6 mm long, 3–6 mm wide, sometimes to c. 15 mm long and 10 mm wide, pungent, glabrous, occasionally puberulous; midrib near abaxial margin. Inflorescences simple, 1 per axil; peduncles 2–4 mm long, glabrous; heads globular, 4-flowered, cream to pale yellow; bracteoles sessile, acuminate; buds attenuate, rather angular when dry. Flowers 4-merous; sepals 1/2–2/3-united, with aristate lobes; petals prominently 1-nerved. Pods narrowly oblong, curved, to 7 cm long, c. 4 mm wide, coriaceous-crustaceous, blackish, glabrous; margins thick. Seeds longitudinal, oblong, 3–4 mm long, glossy, brown, arillate.
Occurs from Yallingup and Boyanup S to near Augusta and Nannup, south-western W.A. Grows in sand, often in swampy areas and along creeks, in open eucalypt forest.
Readily distinguished from other members of the ‘ A. biflora group’ by its aristate calyx lobes, see B.R. Maslin, Nuytsia 2: 305 (1978), for additional distinguishing features.
