Acacia ridleyana is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to an area of western Australia.
The spreading and sprawling shrub typically grows to a height of 0.2 to 0.9 metres (1 to 3 ft)[1] and has hairy branchlets with persistent stipules that have a narrowly triangular shape with a length up to around 2.5 mm (0.098 in). Like most species of Acacia it has phyllodes rather than true leaves. The leathery evergreen phyllodes have a narrowly oblong to linear-oblanceolate shape and are curved in a "S" shape or occasionally straight. The phyllodes are 12 to 25 mm (0.47 to 0.98 in) in length and 2 to 3.5 mm (0.079 to 0.138 in) wide with three strongly raised and distant nerves on each face.[2] It blooms from August to December and produces yellow flowers.[1] The simple inflorescences occur singly in the axils and have spherical flower-heads with a diameter of 5 to 7 mm (0.20 to 0.28 in) and contain 16 to 30 golden coloured flowers. The curved, rigid and leathery seed pods that form after flowering have a compressed-cylindrical shape with a length up to 5.5 cm (2.2 in) and a diameter of 3.5 to 4 mm (0.14 to 0.16 in) and are longitudinally striated.[2]
