Acacia carneorum Maiden (as ‘carnei’), J. & Proc. Roy. Soc. New South Wales 49: 470 (1916)

Needle Wattle , Dead Finish , Purple-wood Wattle

Straggly, spreading, gregarious shrub or tree to 5 m high; habit similar to some Hakea spp. (e.g. H . leucoptera ). Branchlet apices densely tomentulose-puberulous. Phyllodes sessile, patent to inclined, quadrangular in section with a yellow or light brown nerve at apex of each angle, 3–7.5 cm long, 1–2 mm wide, pungent, thick, rigid, appressed puberulous, the indumentum sparse or absent with age. Inflorescences simple, normally 1 per axil; peduncles 8–30 mm long, appressed-puberulous; heads globular, 35–60-flowered, bright golden. Flowers 5-merous; sepals united. Pods rarely produced, narrowly oblong, 2–5 cm long, 8–12 mm wide, thickly coriaceous to woody, dehiscing from apex. Seeds longitudinal, elliptic, c. 6 mm long, aril large and yellowish.

Scattered from SW of Lake Frome and near Peterborough, S.A., to near Tibooburra and Menindee Lakes, N.S.W. Grows on sand ridges or sandy flats in mulga communities or with Callitris glaucophylla , or in alluvium along watercourses in chenopod low shrubland. Flowering is sporadic and probably related to rainfall; apparently few pods are produced.

Following N.Hall & L.A.S.Johnson, The Names of Acacias of New South Wales 34 (1993), the epithet ‘carneorum’ is adopted here instead of ‘carnei’.

An excellent sand binder due to its gregarious, suckering habit.

Biochemically related to A. crombiei and A. peuce , see A. crombiei for note.  See also A. atrox .
