Acacia masliniana R.S.Cowan, Nuytsia 9: 79; 80, fig. 1 (1993)
Maslin's Wattle
Shrub or tree 1–3 m high; trunks and branches somewhat gnarled. Bark fibrous, grey. Branchlets terete, appressed-puberulous at extremities, soon glabrous. Phyllodes ascending to erect, straight to slightly incurved, terete, mostly 5–9.5 cm long, 1.3 mm diam., subulate-pungent, rigid, grey-green to glaucous (green when young), glabrous or sericeous between the nerves, finely multistriate; gland normally 1.5–5 mm above base. Inflorescences simple, 2 per axil; peduncles 0.5–3 mm long, appressed-puberulous to glabrous; heads globular, 4–5 mm diam., 30–45-flowered, golden. Flowers 4- or 5-merous; sepals 1/4–2/3-united. Pods linear, raised over seeds, to 10 cm long, 3–4.5 mm wide, chartaceous, coarsely reticulate over seeds, glabrous. Seeds longitudinal, elliptic-oblong, 4.5–5 mm long, glossy, brown; aril apical.
Found mostly in an area bounded by Twin Peaks, Cue, Perenjori and Youanmi in south-western W.A., but with two outliers in the Kalgoorlie- Kambalda area, c. 300 km SE of Youanmi. Grows at margins of saline lakes, marshes and flats, in clay or loam, in open scrub.
Acacia kalgoorliensis has similar phyllodes except that they have evident stomata in the internerve spaces, it also has fewer-flowered heads and free sepals. May superficially resemble A. donaldsonii or A. rigens .
