Obconic shrub 1–3 (–5) m high. New shoots resinous. Branchlets glabrous except often sparsely and minutely appressed-hairy at apices. Phyllodes terete to flat, mostly ascending to erect, not rigid, narrowly linear, normally shallowly incurved, 60–100 (–120) mm long, 0.5–1.5 (–2) mm wide, short-acuminate with delicate, curved and innocuous tips, glabrous; longitudinal veins numerous, often rather indistinct. Inflorescences 1–2 (–3)-headed racemes; raceme axes 1–10 (–20) mm long, often terminated by vegetative bud or growing out when heads are in bud; peduncles 4–9 mm long, sparsely to moderately appressed hairy, occasionally glabrous; heads globular, 3.5–5 mm diam., 20–30-flowered, light golden, often resinous in bud. Flowers 5-merous; sepals free. Pods narrowly oblong to broadly linear, 30–60 mm long, 7–10 mm wide, firmly chartaceous, mostly shallowly curved, often slightly undulate, obviously raised over seeds alternately on either side, ± glabrous, nerveless or obscurely transversely veined. Seeds transverse to oblique in pods, obloid to ellipsoid or ovoid, 3–3.5 mm long; aril clavate to oblong and ¼–⅓ (–½) as long as seed.
Commonly grows in clay, sandy clay or sandy loam on the slopes of granite and/or basalt hills in very open low woodland and Mallee heath with Triodia ground cover or open Eucalyptus woodland (that includes E. lesouefii) and tall shrubland dominated by Acacia acuminata; the Cundalee plant occurred on red sand.
