Description

The shrub typically grows to a height of 1 to 3 metres (3 to 10 ft).[1] It has ribbed glabrous branchlets with new shoots that are minutely woolly and with caducous stipules with a length of 1.5 to 2 mm (0.059 to 0.079 in). The pungent linear green phyllodes are attenuate at both ends and commonly inequilateral and have a length of 2 to 4.5 cm (0.79 to 1.77 in) and a width of 2 to 4 mm (0.079 to 0.157 in) with two or three main nerves per face.[2] It blooms from August to September and produces yellow flowers.[1] The spherical flower-heads have a diameter of 5 mm (0.20 in) and contain 27 to 35 golden flowers that are sharply inflexed.[2]

Taxonomy

The species was first formally described by the botanist Carl Meissner in 1844 in the Johann Georg Christian Lehmann work Plantae Preissianae.[3][4] It was reclassified as Racosperma benthamii by Leslie Pedley in 2003, but returned to the genus Acacia in 2006.[3] It is closely related to Acacia sessilis and closely resembles Acacia cochlearis.[2]

Etymology

The specific epithet, benthamii, honours George Bentham.[4][5]

Distribution

It is endemic to the west of Western Australia from around Dandaragan in the north[1] to around Subiaco in the south and is commonly found on limestone breakaways.[2]
