|Occurrence data from AVH|
The spreading and prickly shrub typically grows to a height of 0.2 to 0.5 metres (1 to 2 ft). The ribbed branchlets are hairy to woolly with 1.5 to 3 mm (0.059 to 0.118 in) long stipules. The pungent, rigid, green phyllodes have a narrowly lanceolate shape and are straight or shallowly recurved. The phyllodes have a length of 6 to 15 mm (0.24 to 0.59 in) and a width of 1.5 to 2.5 mm (0.059 to 0.098 in) with five nerves and a prominent midrib. It blooms from May to June and produces yellow flowers. The simple inflorescences occur singly in the axilss. The spherical flower-heads contain 13 to 19 golden flowers that are loosely bound. The curved, dark red-brown seed pods that form after flowering have a length of up to 5 cm (2.0 in) and a diameter of 4 to 4.5 mm (0.16 to 0.18 in).
The species was first formally described by the botanist George Bentham in 1942 as part of William Jackson Hooker's work Notes on Mimoseae, with a synopsis of species as published in the London Journal of Botany. It is often confused with Acacia acutata.
It is native to an area along the west coast in the Wheatbelt region of Western Australia between Dandaragan in the north to Mundaring in the south and Dowerin in the east. It is usually found on lateritic ridges and sandplains growing in sandy or gravelly soils as a part of heathland communities.
