Somewhat diffuse, glabrous, viscid shrub, 1–2.5 m high; branchlets ribbed. Phyllodes patent, sessile, narrowly triangular to linear-triangular, 0.5–2.5 cm long, 1.5–3 mm wide, straight or slightly curved, rigid, green, pungent, cusp slender; midrib prominent; gland 0.5–2 mm above base; stipules apparently absent. Peduncles 1 per axil, 5–15 mm long, basal bracts 2; heads globular, 20–25-flowered, cream to pale yellow. Flowers 4-merous; sepals more or less free. Pods linear, to 7 cm long, 3–4.5 mm wide, thinly coriaceous, straight to curved, finely longitudinally and openly reticulate, light brown; seeds longitudinal, oblong to narrowly elliptic, 4.5–5.5 mm long, dark brown, aril terminal.

CVU, DunT, Gold, GGr, MonT, Wim, *HSF. Also SA. Restricted in Victoria to rocky areas around Mt Arapiles and apparently the northern parts of the Grampians (but latter localities not represented in MEL). Seedlings have been reported from near at least one planting elsewhere in the state (Wonga Park). A record of this species from the Little River Gorge in East Gippsland requires further confirmation.

Acacia ulicifolia has somewhat similar phyllodes and heads but it is a non-resinous shrub with 5-merous flowers and non-arillate seeds. Acacia oxycedrus has similar phyllodes except that they are multiveined, and it has spicate inflorescences.
