Acacia insolita is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is endemic to south western Australia.

Description

The shrub typically grows to a height of 0.1 to 1.2 metres (0.3 to 3.9 ft) and has glabrous or hairy stems and foliage. The stems have 1 to 4 mm (0.039 to 0.157 in) long stipules. The leaves have a bipinnate form and are usually persistent on mature plants. Each pinnae normally contain one pair with 2 to 12 pinnules. Each green pinnule has a lanceolate to narrowly oblong or elliptic shape and a length of 5 to 10 mm (0.20 to 0.39 in) and a width 1 to 3 mm (0.039 to 0.118 in). The narrowly linear, flat or quadrangular phyllodes have a length of 1 to 15 cm (0.39 to 5.91 in) and a width of 0.5 to 4 mm (0.020 to 0.157 in).[1] It produces yellow-cream flowers from June to September.[2] The simple inflorescences occur singly in the axils. The spherical flower-heads contain 12 to 19 cream to golden coloured flowers. After flowering linear to narrowly oblong seed pods form with a length of around 8 cm (3.1 in) and a width of 4 to 7 mm (0.16 to 0.28 in). the glossy black to dark brown seeds within the pods are around 3 to 4 mm (0.12 to 0.16 in) in length.[1]
