Distribution

Infrequent from Koolanooka Hills (c. 20 km E of Morawa) E to Evanston (c. 110 km N of Koolyanobbing) and near Mt Correll (Mt Correll is c. 60 km WNW of Koolyanobbing), south-western W.A.

Description

Shrub 0.8–1.5 m high. Branchlets glabrous. Phyllodes 5–10 (–12) mm long, 2–4 (–5) mm wide, thin, glaucous to subglaucous, light green on new shoots, glabrous. Seeds widely elliptic to ±ovate, 3.5–4 mm long, dark brown.

Habitat

Growing in clay or loam, in scrub or woodland.

Specimens

W.A.: 26.5 km from Three Springs on road to Perenjori, I.B.Armitage 368 (PERTH); Evanston, J.S.Beard 4760 (PERTH); 96.5 km from Wubin towards Mt Magnet, B.R.Maslin 3547 (AD, BM, BRI, G, MEL, MO, NSW, PERTH); 3.5 km NNW of Mt Correll, K.Newbey 9595 (PERTH).

Notes

Resembles A. sphenophylla which is distinguished most readily by its green, clearly 2- or 3-nerved phyllodes.

Although individuals of subsp. acanthoclada may have broad glaucous phyllodes or glabrous branchlets and phyllodes, these characters do not occur in combination as in the geographically restricted subsp. glaucescens.
