Distribution

Occurs from near Brookton S to near Albany and E to near Ravensthorpe with one outlier near Esperance, c. 150 km E of Ravensthorpe, south-western W.A.

Description

Branchlets often pruinose apically, glabrous, infrequently minutely pilose. Phyllodes linear, planoconvex, 5–12 mm long, commonly pruinose to subpruinose, 6-nerved in all, with adaxial nerve indistinct or not apparent and 3 abaxial nerves prominent; upper surface with gland near middle of phyllode, often absent or obscure. Peduncles (2–) 5–8 mm long, glabrous. Pods to 3 cm long, 3–4 mm wide, pruinose. Seeds ovate, 2 mm long.

Habitat

Grows in sand, sandy gravel, sandy loam and rocky loam, in dense scrub, mallee heath and mallee shrubland, frequently on hills and mountains in association with granite.

Specimens

W.A.: 30.5 km E of Brookton towards Corrigin, R.J.Cumming 1037 (PERTH); 30.5 km N of Esperance, H.Demarz 3635 (PERTH); 16 km S of Jerramungup towards Albany, B.R.Maslin 2590 (CANB, PERTH); c. 32 km E of Albany towards Jerramungup, S.Paust 485 (PERTH); Kojonup, 15 Aug. 1969, M.Wittwer s.n. (PERTH).

Notes

Glaucous or pruinose specimens are similar superficially to the narrow phyllode form of A. leptospermoides subsp. leptospermoides, a diaphyllodinous species (for definition and references concerning diaphyllodes, see discussion under A. diaphyllodinea) which has obscurely nerved phyllodes, larger heads with twice as many flowers and curved to coiled pods.
