Tree to 15 m high; trunk to 20 cm d.b.h. Branchlets glabrous, lenticellate. Phyllodes narrowly elliptic, straight to shallowly recurved, 8–14.5 cm long, 7–16 (–25) mm wide, acute, thinly coriaceous, glabrous, with 6–11 main nerves and numerous longitudinally anastomosing minor nerves inbetween; gland 3–15 mm above pulvinus. Inflorescences 1- or 2-headed racemes, up to 8 heads per axil; raceme axes 0.5–2 mm long, glabrous; peduncles 5–15 mm long, glabrous; heads globular, 5.5–6 mm diam., 25–35-flowered, golden. Flowers 5-merous; sepals free. Pods linear, raised over and not or scarcely constricted between seeds, to 9 cm long, 12 mm wide, coriaceous, transversely reticulate, glabrous. Seeds longitudinal, subcircular, 4.5–5 mm long, 3.5–4 mm wide, dull, brown; funicle slightly thickened into a narrowly clavate aril.
Restricted to the area in which the type collection was made, SE of Cairns, Qld. Grows in rainforest.
Seemingly closely related to A. armillata . May resemble A. legnota which has strongly falcate phyllodes, longer peduncles and non-reticulate pods.
