Bushy shrub 3–4 m high. Branchlets finely ribbed, appressed-puberulous, glabrescent except at nodes. Phyllodes narrowly linear, 12–19 cm long, 1–2 mm wide, delicately acuminate and innocuous, not rigid, with appressed, brown resin-hairs at first, glabrescent, with 3 distant, raised nerves. Inflorescences 1–5-headed racemes, sometimes appearing simple; raceme axes 0.5–2 mm long, appressed-puberulous; peduncles 10–13 mm long, glabrous to appressed-puberulous; heads globular, 4.5 mm diam., 25-flowered, pale yellow. Flowers 5-merous; sepals free. Pods linear, flat, slightly raised over and irregularly constricted between seeds, to 10 cm long, 6–7 mm wide, chartaceous, glabrescent; margins thickened. Seeds (immature) longitudinal, elliptic to elliptic-oblong, 4.5 mm long; funicle filiform, gradually thickening to a slight aril.
Known only from Chewings Ra., southern N.T. Grows in steep sheltered gullies in schistose hills.
Related to A. tenuior , which differs, perhaps only infraspecifically, in its terete phyllodes. Superficially resembling A. praelongata and A. estrophiolata .
