Acacia baxteri, commonly known as Baxter's wattle, is a shrub belonging to the genus Acacia and the subgenus Phyllodineae, and is endemic to the south west of Western Australia.

Description

The compact and pungent shrub typically grows to a height of 0.2 to 1 metre (1 to 3 ft). It blooms from September to December and produces yellow flowers. The shrub has rigid, striate-ribbed and glabrous branchlets. The thick rigid phyllodes are sessile, with a narrowly linear to oblong-elliptic shape and are around 10 to 25 millimetres (0.39 to 0.98 in) in length with a width of 1 to 4 mm (0.04 to 0.16 in). There is one simple inflorescence per axil with globular flower heads containing 30 to 50 flowers. After flowering curved woody red-brown seed pods form that are up to 6.5 millimetres (0.26 in) long and 3 to 5 mm (0.12 to 0.20 in). The grey-brown seeds have an oblong shape and are 5 to 6 mm (0.20 to 0.24 in) in length.
