Family

Fabaceae

Distribution

Widespread and scattered from Wubin (c. 20 km due N of Dalwallinu) and Kondinin E to near Menzies (c. 125 km due NNW of Kalgoorlie), Kitchener (c. 160 km due NNE of Balladonia) and Balladonia, W.A.

Description

Shrub 0.4–2 m high. Phyllodes 2–6 cm long but most commonly 2.5–4.5 cm long, 0.6–1 mm diam. Peduncles 1–2 mm long, glabrous to sparsely puberulous, with red resin-hairs present or absent, rarely densely tomentulose; heads less than 20-flowered. Pods straight, 2–5 cm long, 1.5–2 mm wide, glabrous or with red resin-hairs. Seeds elliptic.

Habitat

Usually grows in sand or loam, predominantly in low eucalypt woodland and mallee or mixed shrubland.

Specimens

W.A.: 29 km N of Kondinin towards Narembeen, B.R.Maslin 3423 (CANB, K, PERTH); 3.5 km S of Wubin on road to Dalwallinu, B.R.Maslin 4974 (CANB, K, PERTH); near Lake Dundas, I.V.Newman 771 (NSW, PERTH); 33 km W of Balladonia on Eyre Hwy, M.H.Simmons 1160 (PERTH); 5 km W of Kitchener, J.Taylor 545, M.D.Crisp & R.Jackson (NSW, PERTH).

Notes

The phyllode apex is straight instead of deflexed in populations from the Peak Charles–Dundas area, S and SW of Norseman (e.g. I.V.Newman 771, PERTH). A collection by C.A.Gardner from Bendering (NSW, PERTH) is unusual in having densely tomentulose peduncles.

Acacia papulosa is similar to the typical variety.
