Acacia grisea is a shrub of the genus Acacia and the subgenus Pulchellae that is endemic to an area of south western Australia.
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]
It is closely related to Acacia browniana which is found closer to the coast. [2]
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.
