Multi stemmed, glaucous shrub 0.3–2 m high. Bark smooth, grey-brown, greenish brown or yellow-brown. Branchlets terete, pilose with soft white hairs; ridges inconspicuous. Young foliage-tips greenish white, pilose. Leaves herbaceous or subcoriaceous, ±silvery glaucous; petiole 0.1–0.6 cm long, terete, shortly pilose, mostly with a raised glabrous or pilose orbicular gland c. 0.1–0.3 mm diam. at base of or just below lowest pair of pinnae; rachis (0.2–) 0.5–1.5 (–2.3) cm long, shortly pilose, occasionally with a similar gland at base of apical pair of pinnae; interjugary glands absent; pinnae 2–4 (–5) pairs, (0.5–) 0.8–1.5 (-2) cm long; pinnules 5–11 pairs, narrowly oblanceolate or oblanceolate, sometimes cultrate, 2–7 mm long, 0.5–1 mm wide, with often slightly recurved margins, glabrous or very sparsely pilose towards apex and on margins, with midnerve obscure, almost central, apically acute, bluntly apiculate or broadly rounded. Inflorescences in axillary racemes or mainly terminal false-panicles. Peduncles 2.5–5 mm long. Heads globular, 11–22-flowered, golden or yellow.

Habitat

Grows in ironbark eucalypt (Eucalyptus melanophloia etc.)–Callitris columellaris –Casuarina woodland, in sandy or gravelly soils.

 

 

Notes

Closely allied to Acacia polybotrya but differing in fewer flowers per head, pinnae smaller and narrower (5–10 mm wide), pinnules smaller, non-sulcate, with midnerve obscure and basal lateral nerves absent, calyces shorter being 1/3 length of corollas instead of 1/2, and lobes of calyces triangular, dissected to 1/5 of length of tube. Acacia chinchillensis is restricted to Qld where it has a more northerly distribution than A. polybotrya and occurs in drier country. The latter species extends from the Darling Downs District, Qld, to North Western Plains, N.S.W. (especially Pilliga Scrub) and North and Central Western Slopes. Also related to another Qld endemic, A. argentina.
