Acacia colletioides A.Cunn. ex Benth.

Shrub or tree 0.5–3 m high, rigid, diffuse to dense. Branchlets glabrous or sparsely appressed-puberulous and glabrescent, scarred where phyllodes have fallen. Phyllodes sessile, inserted on distinct yellow stem-projections, patent to ascending, straight to ±curved, ±terete, (1–) 1.5–3 (–4) cm long, 1–1.5 mm diam., subulate, pungent, rigid, glabrous, with 8 strongly raised lighter coloured veins and raised stomata; gland 0–2 mm above pulvinus. Inflorescences simple, 2 per axil; peduncles 1.5–5 mm long, glabrous; basal bracts cucullate, ±semicircular; heads subglobular, often widely ellipsoid, 3–5 mm long, 3–4.5 mm diam., 12–24-flowered; bracteoles peltate. Flowers mostly 5-merous; sepals free. Pods linear, constricted between seeds, 1-or 2-coiled, to 7 cm long, 3–5 mm wide, thin-coriaceous, ±reticulate, glabrous. Seeds longitudinal, oval to ovate, 3.5–4 mm long, shiny, black; aril nearly enveloping seed, orange or yellow.

Usually found as scattered individuls in mallee scrub or open woodland, growing in a variety of soils.
