Erect shrub or tree to 7 m high with rather straight trunks. Branchlets terete, resin-ribbed when young, glabrous except occasionally minutely hairy in phyllode axils. Phyllodes ascending to erect, linear, straight, rhombic in section, occasionally flat, 8–18 cm long, 1–1.5 wide, to 3 mm wide when flat, with a gently recurved-acuminate apex, glabrous, with a resinous nerve at apex of each of the 4 angles and with numerous finer nerves on the intervening faces; central nerve evident when phyllodes flat. Inflorescences simple; peduncles 2.5–6 mm long, glabrous, often granular resinous; heads obloid to short-cylindrical, 6–15 mm long, golden. Flowers 5-merous; sepals 3/4-united. Pods linear, raised over and constricted between seeds, straight, to 6 cm long, 2 mm wide, chartaceous, glabrous. Seeds longitudinal, elliptic-oblong, 2.5–3.5 mm long, semi-glossy, mottled dark and lighter brown; aril apical, crested.
Common from Perenjori SE to near Kambalda, also N to Leonora, inland south-western W.A. Grows in sand, rarely in loam, in scrub and shrubland, often in pure stands.
Related to A. jamesiana which has rigid phyllodes with straight apices, larger pods and non-mottled seeds.
