Acacia sclerophylla var. pilosa R.S.Cowan & Maslin




A poorly collected taxon known only from a few localities between Kununoppin and Dumbleyung in south-western W.A.


Branchlets short-pilose to pubescent at extremities (hairs relatively long, weak and spreading to appressed), often soon becoming glabrous. New shoots moderately to densely hairy. Stipules linear-triangular, 1.5–2.5 mm long. Phyllodes linear to linear-oblanceolate, (10–) 20–35 mm long, 2–3 mm wide, flat, hairy when young (indumentum similar to branchlets except hairs sometimes shorter), glabrous with age, with 3–5 (–7) longitudinal nerves. Old pod valves coiled, sparsely to densely hairy.


Grows in sandy loam or clay in mallee, sometimes at margin of salt flat.


W.A.: ‘Ryans Property’, Doodlakine–Kununoppin road, 26 Aug. 1987, L.Atkins s.n. (CANB, K, MEL, NY, PERTH) and 14 Oct. 1987 (PERTH); North Bungulla Reserve, N of Bungulla on road to Yorkrakine, R.S.Cowan A742 & B.R.Maslin (BRI, CANB, K, MEL, NSW, PERTH); between Lake Grace and Kulin, N.Perry 518 (PERTH).


Variety pilosa differs from the other elements of A. sclerophylla principally by its densely hairy branchlets and (at least when young) phyllodes, as well as by its longer stipules. Similar also to A. caesariata.
