Description

The dense shrub typically grows to a height of 0.6 to 1.6 metres (2 to 5 ft)[1] with grey-green to blue-green coloured glabrous ribbed branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen and erect phyllodes have a narrowly linear to linear-oblanceolate shape with a length of 2.5 to 4 cm (0.98 to 1.57 in) and a width of 2 to 4 mm (0.079 to 0.157 in). The thick rigid grey-green phyllodes have six raised nerves.[2] It blooms in August and produces yellow flowers.[1]

Taxonomy

The species was first formally described by the botanist George Bentham in 1855 as part of the work Plantae Muellerianae: Mimoseae as published in Linnaea: ein Journal für die Botanik in ihrem ganzen Umfange, oder Beiträge zur Pflanzenkunde. It was reclassified as Racosperma durum by Leslie Pedley in 2003 then transferred back to genus Acacia in 2006.[3] The type specimen was collected by James Drummond.[2]

Distribution

It is native to an area in the Wheatbelt region of Western Australia growing in sandy to sandy-loamy soils often over or around areas of laterite.[1] The distribution of the shrub is limited to a small area from between Wongan Hills and Piawaning as a part of sandy heathland communities where it is often associated with Melaleuca uncinata.[2]
