Scattered from Mt Holland (c. 85 km due NE of Hyden) and Lake King E to Kumarl and Scaddan (which are located between Norseman and Esperance) in south-western W.A. Grows in loam or loamy clay and sand, in open scrub and shrubland mallee.
A member of the ‘ A. densiflora group’, nearest A. undosa which has much thinner, linear to oblanceolate-linear phyllodes with more nerves and undulate pods. There is also a superficial resemblance to A. amyctica .
