Acacia alpina F.Muell.

Shrub 0.5–2 m high, 1–10 m wide, sometimes almost prostrate, tangled. Branchlets glabrous. Stipules caducous, deltate, 0.5–1 mm long. Phyllodes normally obovate or suborbicular, commonly asymmetrical, 1.5–3.5 (–4.5) cm long, 8–25 (–27) mm wide, with a rounded (not mucronulate), straight, occasionally emarginate apex, coriaceous, dull green to dull grey-green or greyish; primary veins 2–4; secondary veins anastomosing (closely reticulate) and conspicuous; gland small or obscure, 2–9 mm above phyllode axil; pulvinus 1–3 mm long. Inflorescences with peduncles 1–4 mm long and glabrous; receptacles glabrous; spikes solitary or twinned, oblong or cylindrical, 5–15 mm long, interrupted, pale yellow, sometimes bright yellow; bracteoles cymbiform, 0.4–1 mm long, 0.3–0.8 mm wide. Flowers 4-merous; sepals united. Pods submoniliform or occasionally linear, gently curved or coiled, thin-walled, 3–8 cm long, 3–6 mm wide. Seeds narrowly elliptic, 3.5–5 mm long; funicle folded 3–8 times; aril turbinate.

It occurs most frequently in granitic tracts and seems to be confined to habitats between 1300 and 1800 m altitude. Sometimes it thrives well in windswept areas and occasionally forms impenetrable thickets.
