Specimens

Qld: Mt French, 12 km SW of Boonah, L.H.Bird AQ473431 (BISH n.v., BRI n.v., CANB, K n.v., MEL n.v., MEXU n.v., MO n.v., NSW, PERTH); Mt Maroon, S.L.Everist 7110 (BRI): Mt Gillies, 20 km SW of Rathdowney on Mt Lindsay Hwy, P.Sharpe 1072 (BRI); Mt Barney, C.T.White 7843 (BRI).

Notes

Most closely related to A. floydii which has slightly narrower phyllodes with more prominent glands nearer the base and fewer flowers per head. Formerly confounded with A. adunca which has bright golden flower-heads and uncinate, thicker, generally narrower phyllodes. Phyllodes ±resembling those of A. macnuttiana.
