Shrub 1-2.5 m high, bushy, spreading, slightly resinous, glabrous. Phyllodes asymmetrically lanceolate to narrowly elliptic, sometimes substraight to shallowly recurved or sometimes shallowly sigmoid, 3-5 (-6) cm long, 4-7 (-9) mm wide, acute to acuminate (the apical point thickened and conical), bright green, with longitudinal nerves numerous but mostly very indistinct (obscured by fine longitudinal wrinkling when dry) but with 1-3 nerves commonly more evident than the rest; nerves not anastomosing. Inflorescences simple, 1 or 2 in axils; spike obloid to shortly cylindrical, 7-15 (-20) mm long, golden; peduncles 10-20 (-23) mm long. Flowers 5-merous; buds ±acute and subdensely arranged. Pods (only a few fragmentary valves seen, these appear generally similar to those of A. ancistrocarpa ) 5-7 mm wide, narrowed at base, dark brown, longitudinally nerved; margins slightly thickened.
