Occurs from Ravensthorpe to S of Kundip and E to Munglinup, and in the Scaddan–Wittenoom Hills area, W.A.


Harsh much-branched shrub to 1.5 m high. Branchlets densely puberulous. Stipules caducous or persistent, scarious. Phyllodes ±crowded, sessile to subsessile, scimitar-shaped, strongly recurved, (5–) 10–20 mm long, 1–3 mm wide, pungent, rigid, glabrous, with 3 prominent distant main nerves. Inflorescences simple, commonly 1 per axil; peduncles 5–9 mm long, glabrous; basal bract 1–1.5 mm long, brown; heads globular, 3–3.5 mm diam., 13–25-flowered, golden; bracteoles minute. Flowers 5-merous; sepals free. Pods linear, raised over seeds, strongly curved, to 5 cm long, 4–4.5 mm wide, firmly chartaceous to thinly coriaceous-crustaceous, glabrous. Seeds longitudinal, nearly round to subquadrate, turgid, c. 2.5 mm long and wide, slightly shiny, dark brown; aril subapical.


Grows in clay, clay loam or lateritic gravel, mostly in open scrub.


W.A.: Wittenoom Hills, T.Daniells s.n. (PERTH00713465); S of Ravensthorpe, A.S.George 4422 (MEL, PERTH); c. 20 km SW of Scaddan, B.R.Maslin 2527 (PERTH); Munglinup area, B.R.Maslin 4482 (PERTH).


Related to A. campylophylla which has branchlets glabrous, stipules ±spinose, phyllodes ±continuous with the branchlets, bracteoles spathulate, acuminate and strongly exserted in buds, and pods straight. Perhaps with affinities to A. acellerata.
