Specimens

W.A.: 4 km N of Dowerin towards Cadoux, R.Cumming 1850 (CANB, PERTH); 18 km WNW of York, G.J.Keighery & J.Alford 172 (PERTH); c. 19 km S of Tammin, B.R.Maslin 602 (MEL, PERTH); 10 km N of Corrigin towards York, E.Pignatti 417 (PERTH).

Notes

The Drummond ‘n. 41 of some other set’ referred to as this species by G.Bentham, Fl. Austral. 2: 326 (1864), is A. acellerata, judging from a duplicate at Herb. NSW (sheet NSW216948).

Related most closely to A. chapmanii and A. curvata; similar in phyllodes to A. wilsonii.
