Plants with hairy phyllodes are common in the Grampians but occur less frequently elsewhere (e.g. Muckleford, Swanpool). Phyllodes vary in size and orientation between populations, sometimes few being reflexed.
Differs from A. ulicifolia and A. brownii in having phyllodes often reflexed, and flowers 4-merous. See also notes under A. genistifolia.
