W.A.: near Coorow, July 1962, L.C.Chapman s.n. (BRI, PERTH).


Related to A. arcuatilis (which has generally shorter phyllodes and fewer-flowered heads) and A. lirellata subsp. lirellata (which has decurrent, deeply furrowed phyllodes). Also related to A. filifolia which is distinguished by its wispy, slightly taller stature and longer, generally thinner phyllodes.
