Distribution

Occurs from Nannup S to Mt Chudalup (near Northcliffe) and Walpole, W.A.

Description

Shrub 1–2 m high. Branchlets hirsutellous to ±puberulous, sometimes pilose admixed; hairs patent, straight or incurved and often tubercle-based. Distal pinnae 5–20 mm long; pinnules 2–8 pairs on distal pinnae, 2–6 mm long, 1–2 mm wide, flat or slightly recurved, sparsely to moderately hirsutellous on margins and sometimes the lower surface. Peduncles glabrous or (at least near their base) puberulous; flower-heads cream.

Habitat

Usually grows in loam in Karri (Eucalyptus diversicolor) and Karri-Jarrah (E. diversicolor -E. marginata) forest.

Specimens

W.A.: 1.6 km W of Donnelly R. crossing on Manjimup–Nannup road, B.R.Maslin 2864 (BRI, CANB, K, MEL, PERTH); Mt Chudalup, B.R.Maslin 2900 (PERTH).

Notes

Possibly hybridises with variants 1 and 2 of var. browniana in the Walpole and Manjimup areas respectively. Sterile specimens from around Manjimup can be confused with A. lateriticola.
