Phyllodes mostly fasciculate and crowded at mature nodes on short nodose branchlets, cuneate-oblanceolate, 3–7 mm long, 1–2 mm wide, ±obtuse and obliquely mucronulate, thick but flat, green; midrib submerged, not prominent; lateral nerves absent. Inflorescences simple, 1–4 per axil; peduncles 6–15 mm long, ebracteate at base; heads globular to slightly obloid, 5–6 mm diam., mostly 20–30-flowered, golden. Flowers 5‑merous; sepals free. Pods narrowly oblong, to 2 cm long, 5–9 mm wide, firmly chartaceous, undulate or twisted at dehiscence. Seeds ±spherical, c. 3 mm diam., dull, dark brown; aril conspicuous, curving ±1/2-way around seed, cream.


Grows in rocky loam and loamy sand or clay, often over jasperlite, in open Eucalyptus ebbanoensis mallee shrubland.


W.A.: type locality, K.Newbey 9204 (NSW, PERTH).


Similar to A. nodiflora in its fascicled phyllodes with the peduncles arising from the fascicles, but that species has longer, linear phyllodes, spiny stipules, sometimes bracts on the peduncles, much longer pods and oblong seeds.
