Acacia profusa Maslin, Nuytsia 12: 383 (1999)
Compact to open shrub 0.3–0.9 m high. Branchlets glabrous, sometimes resinous and vernicose. Phyllodes crowded, on raised stem-projections, erect or ascending, linear, straight or shallowly incurved, 7–17 mm long, 1–1.5 mm wide, narrowed at base, obliquely mucronate, slightly thickened, glaucous (at least when young), glabrous, 3-nerved in all; midrib immersed and not or scarcely evident; nerve on abaxial margin yellow to brown; adaxial marginal and lateral nerves absent; gland 0.2–1.5 mm above base. Inflorescences rudimentary, 1 (2)-headed racemes with axes 0.5–1 mm long; peduncles 9–16 mm long, glabrous; basal bract persistent; heads globular, 4.5–5 mm diam., 10–17-flowered, golden; bracteoles absent. Flowers 5-merous; sepals free or united near base. Pods oblong to narrowly oblong, prominently raised over seeds alternately on each side, to 25 mm long, 10–12 mm wide, chartaceous, glabrous. Seeds transverse, broadly elliptic, c. 5 mm long; funicle gradually thickened to once-folded, subterminal aril.
Occurs in an area bounded on the N by Frank Hann Natl Park, Peak Eleonora and Kumarl (all S or SSW of Norseman), SE to Mt Ridley (c. 65 km due NE of Esperance), W.A. Grows in clay, sandy loam or loamy clay on flats, in open shrub mallee, open dwarf scrub or low heath.
Phyllode venation as in A. carnosula to which it is possibly related. Glabrous variants of A. lachnophylla , another possible relative, have phyllodes with the gland more than 4 mm above the pulvinus, and narrow, coiled pods.
