Acacia grisea is a shrub of the genus Acacia and the subgenus Pulchellae that is endemic to an area of south western Australia.

Description

The shrub to subshrub typically grows to a height of 0.1 to 0.6 metres (0.3 to 2.0 ft)[1] and has hairy branchlets with two pairs of pinnae and the proximal pinnae have a length of 2 to 4 mm (0.079 to 0.157 in) and the distal pinnae have a length of 5 to 10 mm (0.20 to 0.39 in) with two to three pairs of proximal pinnules on the proximal pinnae and four to seven pairs of pinnules on the distal pinnae. The slightly thickened, hairy, grey-green pinnules have a more or less oblong shape and are 2 to 4 mm (0.079 to 0.157 in) in length and 1 to 2 mm (0.039 to 0.079 in) wide.[2] It blooms from June to August and produces yellow flowers.[1] The simple inflorescences occur singly in the axils and have spherical flower-heads containing 16 to 26 golden coloured flowers. The hairy seed pods that form later have a length of 2 to 4 cm (0.79 to 1.57 in) and contain oblong to elliptic shaped seeds that are about 3 mm (0.12 in) in length.[2]
Taxonomy

It is closely related to Acacia browniana which is found closer to the coast.[2]
Distribution

It is native to an area in the Wheatbelt and Great Southern regions of Western Australia where it is commonly situated on slopes and undulating plains growing in gravelly loamy lateritic soils.[1] The range of the plant extends from around Kukerin in the north to around Kojonup in the south west and Brommehill in the south east.[2]
