Acacia baxteri Benth. (as ‘bagsteri’), London J. Bot . 1: 327 (1842)
Shrub 0.3–0.6 m high. Branchlets rigid, striate-ribbed, sometimes pruinose, glabrous. Stipules 1–3 mm long, spinose. Phyllodes sessile, variable, narrowly linear to inequilaterally narrowly oblong-elliptic, pentagonal-terete when narrow, 10–25 mm long, normally 1–4 mm wide, with oblique, pungent apex, thick, rigid, subglaucous (? or green), glabrous, 5-nerved, the 2-nerved adaxial margin thick and nerve-like; midrib prominent. Inflorescences simple, 1 per axil; peduncles 3–10 (- 15) mm long, stout, glabrous; heads globular, 30–50-flowered, golden. Flowers 5-merous; sepals free; petals nerveless. Pods curved, terete to subterete, to 6.5 cm long, 3.5–5 mm wide, subwoody, dark red-brown, glabrous. Seeds longitudinal, oblong, 5–6 mm long, grey-brown; aril terminal, conical, small.
Disjunct in south-western W.A. with the main occurrence from Ongerup to Albany, infrequent further N between Walebing and Quairading. Grows in often lateritic or granitic sand or loam, in Eucalyptus woodland or open Mallee heath. Flowers during most months of the year.
Erroneously described as ‘A. bagsteri’, fide G.Bentham, Fl. Austral . 2:328 (1864).
Branchlets on plants from the northern-most populations are more pruinose than elsewhere; the relationship between these populations and A. affin. baxteri requires further investigation.
A taxon of uncertain rank but with affinities to A. baxteri (especially the northern pruinose populations) is keyed and described separately in WATTLE as A. affin. baxteri .
