Acacia aculeiformis

Acacia aculeiformis is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is prostrate, scrambling, mat-forming shrub with asymmetrical elliptic to narrowly elliptic phyllodes, and spherical heads of light to medium golden-yellow or yellowish-red flowers.

Description
Acacia aculeiformis is a prostrate, scrambling, mat-forming shrub that has many stems and that typically grows up to 2 m wide. Its phyllodes are more or less glabrous, asymmetrical elliptic to narrowly elliptic, 10–25 mm long, 5–10 mm wide with spiny stipules 2.5–4 mm long at the base. Between 27 and 39 light to medium golden-yellow or yellowish-red flowers are arranged in 1 or 2 spherical heads 0.5–1 mm long on a peduncle 6–17 mm long. Flowering has been observed from August to January.

Taxonomy
Acacia aculeiformis was first formally described in 1999 by Bruce Maslin in the journal Nuytsia from specimens he collected 10.5 km north of Three Springs in 1983. The specific epithet (aculeiformis) means "prickle-shaped" and refers to the stipules.

Distribution and habitat
This species of wattle occurs in scattered locations from Mogumber and Three Springs in gravelly soils on rocky rises, breakaways and hills in the Avon Wheatbelt, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.
