Multi-stemmed shrub maturing to shapely, obconic tree 3–8 (–10) m high; crowns dense and silvery bluish grey, grey or grey-green tinged blue. Branchlets densely appressed-pubescent between rather obscure resinous ribs towards apices; resin normally not well-developed; new shoots not or scarcely resinous; youngest phyllodes densely tomentulose (hairs usually white) except for dark-coloured, resinous marginal vein, sometimes (in narrow-phyllode variant) indumentum less prominent with hairs confined to between longitudinal veins. Phyllodes variable, straight and dimidiate to falcately recurved, commonly narrowly oblong to elliptic, not rigid, (2–) 3–7 (–8) cm long, (2–) 2.5–10 (–12) mm wide; longitudinal nerves numerous and often appressed-hairy between; broadest phyllodes sometimes felty; marginal nerve resinous but often not especially prominent; resin normally milky white or yellow (sometimes light brown on oldest phyllodes). Inflorescences simple; peduncles 2–10 mm long, often densely appressed-hairy; spikes 10–20 mm long. Flowers 5-merous; sepals ½ or slightly more than ½ length of petals. Pods oblong, 1.5–3.5 (–4.5) cm long, (7–) 10–15 (–20) mm wide including wings 1–2 (–2.5) mm wide, firmly chartaceous, flat, greyish brown, obscurely reticulate. Seeds oblique to transverse, 4–6 (–7) mm long, 2–3 (–3.5) mm wide, oblong to ±elliptic; aril small and whitish.
Commonly grows on plains or in gently undulating country in red-brown sandy loam to clay, often over hardpan at a relatively shallow depth, in mixed Acacia shrubland or woodland communities dominated by Mulga species (especially Acacia incurvaneura).
