Multistemmed shrub or fastigiate tree to 7 m high. Bark corrugated, fissured, dark grey. Branchlets angular, pinkish to dull purplish red, sometimes mealy, glabrous, often resinous. Phyllodes linear, flat, straight to shallowly incurved, 5–21 cm long, 1.5–4 (-6.5) mm wide, coriaceous, scurfy, glabrous, the minor veins c. 8 per mm, inconspicuous, parallel, not anastomosing, the midvein evident; gland 1, rudimentary, basal, to 1.5 mm above pulvinus. Spikes in short racemes, 1–3.5 cm long, golden. Flowers 5-merous; calyx 0.5–1.1 mm long, dissected to 1/4, sparsely hairy at base and apex; corolla 1.2–1.8 mm long, glabrous; ovary glabrous or with apical hairs. Pods linear, raised over seeds, 6–8 cm long, wrinkled, glabrous. Seeds longitudinal, oblong-elliptic, 4–4.5 mm long, dark brownish black; pleurogram slightly paler, open, without halo; areole brownish black.
Widespread in inland south-eastern Qld and north-eastern N.S.W. between Moura and Gilgandra, on sandy, often alluvial soils usually in open eucalypt forests and woodlands often dominated by Callitris , and frequently in disturbed areas. Flowers mainly Aug.–Oct.
It is related to A. granitica which has almost sessile spikes, and to A. burrowii which has broader phyllodes, mostly shorter calyces and longer corollas, but it lacks the broad juvenile phyllodes of the latter. Closely related to A. doratoxylon .
