Acacia rossei F.Muell., Victorian Naturalist 10: 55 (1893)
Spindly, open, sparingly branched, glabrous, somewhat viscid shrub 1–3 (- 5) m high. Branchlets roughened by obvious stem-projections where phyllodes have fallen. Stipules setaceous, 2.5–4.5 mm long. Phyllodes crowded, patent to erect, linear, straight to shallowly curved, flat or (when dry) quadrangular, 1–3 cm long, 1–1.5 mm wide, obliquely and excentrically mucronate, slightly thickened, green; midrib and abaxial nerves resinous (resin often in beads); gland basal. Inflorescences comprising terminal false racemes which grow out at anthesis; peduncles 2–3 cm long, normally subtended by immature phyllodes, the base ebracteate; heads globular, densely 65–75-flowered, golden. Flowers 5-merous; sepals united at base. Pods narrowly oblong, 2.5–5 cm long, 7–11 mm wide, crustaceous, roughened by prominent brown excrescences. Seeds transverse to oblique, oblong to widely elliptic, 4–5 mm long, arillate.
Occurs from Kellerberrin E to Yellowdine and S to near Hyden, south-western W.A. Common where it occurs, especially in disturbed sites, e.g. roadverges, regeneration following fire. Grows in tall shrubland, usually in yellow sand.
