Family

Fabaceae

Distribution

Occurs inland from southern end of Shark Bay E to Meekatharra and Bulloo Downs Stn. (c. 75 km S of Newman), W.A.; in a few locations near populations of the typical subspecies.

Description

Phyllodes narrowly linear, compressed, ranging to terete or flat, 5–11 cm long, 1–1.5 mm wide, l:w = 33–110; nerves not anastomosing. Seeds broadly elliptic to turgidly subdiscoid, 8–9 mm long.

Habitat

Grows commonly in often stony sand and clay on gibber plains or stony rises along creek lines, sometimes in saline conditions.

Specimens

W.A.: 18 km E of Meekatharra on road to Wiluna, J.W.Green 5301 (K, PERTH); c. 5 km S of Meekatharra on Great Northern Hwy, B.R.Maslin 5387 (PERTH); Bulloo Downs on Meekatharra Rd, 15 June 1976, A.A.Mitchell s.n. (PERTH); 3.2 km W of Weedarrah Outcamp, Bidgemia Stn, D.G.Wilcox 163 (PERTH).

Notes

The B.Kok specimen from Tangadee Stn. (PERTH00605905) noted in R.S.Cowan & B.R.Maslin, Nuytsia 10: 25 (1995), has hairy phyllodes but the indumentum is sparser than is normal for the subspecies.

Very close to A. wanyu; the possibility of hybrids between the two species is discussed under A. wanyu.
