Single-stemmed shrub or tree to 8 m high. Bark rough to ‘ironbark’-type, black. Branchlets angular, brown or orange-brown, sometimes slightly pruinose, velvety-pubescent; ridges not prominent. Phyllodes narrowly elliptic, elliptic or narrowly obovate, straight, 2–8.5 (–10) cm long, 8–30 mm wide, silvery, velvety-pubescent, later puberulous, with 1–3 slightly prominent main nerves reaching apex and base, the minor nerves 5 or 6 per mm, not anastomosing; gland 1, small, basal, hairy. Spikes almost sessile, 2–5 cm long, golden. Flowers 5-merous; calyx 0.5–0.9 mm long, truncate or dissected to c. 1/6, white-pubescent, papillose at apices; corolla 1.6–1.8 mm long, dissected to 1/2–5/8, glabrous; ovary villous. Pods linear, slightly constricted between and slightly raised over seeds, 3–8 cm long, 3–4 mm wide, chartaceous, greyish, longitudinally nerved, pubescent. Seeds longitudinal, oblong-elliptic, 4–4.5 mm long, black; pleurogram indistinct, narrowly U-shaped.
Occurs in the Darling Downs District, south-eastern Qld, from Glen Aplin to Wallangarra, common near Wyberba, S of Stanthorpe; less common in N.S.W. where it is recorded from Torrington State Recreation Area (NW of Emmaville) and near Warrabah National Park (c. 60 km W of Armidale). Grows on rocky granite hillsides, in sandy, stony or loam soil in eucalypt-scrub woodland or Eucalyptus - Callitris forest. Flowers Sept.–Nov.
Has been observed to benefit from disturbance. Closely allied to A. striatifolia which may be easily distinguished by its glabrous phyllodes and ovaries.
