Distribution
Widespread from inland of Shark Bay and Kalbarri, W.A., eastward to S of Tennant Creek, central N.T.
Description
Phyllodes elliptic to narrowly elliptic or linear-elliptic, flat, 3–8.5 cm long, 3–10 (–20) mm wide, l:w = 2.5–14; central nerve the most evident; lateral nerves when present longitudinally orientated and sometimes sparingly to moderately anastomosing. Seeds broadly elliptic, 7.5 mm long.
Habitat
Commonly in stony sand along creeks and drainage lines, often on hillocks but also on plains, mostly with mulga and spinifex.
Specimens
W.A.: Wiluna Rd, 80 km W of Carnegie, U.Johnson 41 (K, NSW, PERTH); Mt James Stn, 53 km N of Landor HS on track to Mt Augustus Stn, B.R.Maslin 5189a (PERTH); 30.5 km N of Gordon Downs Stn, R.A.Perry & M.Lazarides 2439 (CANB n.v., NSW, PERTH).

Notes
There is considerable variation in phyllode width and shape with very narrow phyllode forms approaching subsp. linearis whose phyllodes are much longer in relation to their width.
Acacia levata was formerly confused with this subspecies.
