Specimens

W.A.: c. 15 km S of Tambellup on Great Southern Hwy, C.Dziekanowski & J.Roethke 3806 (CANB, PERTH); c. 4.8 km due NW of Mt Bland, B.R.Maslin 1044 (CANB, PERTH); 25 km ENE of Jerramungup, K.Newbey 9533-1 (MELU, PERTH).

Notes

Perhaps with affinities to A. curvata or A. leptoneura.

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