Acacia asepala

The diffuse and multi-branched shrub typically grows to a height of 0.5 to 1.5 metres (2 to 5 ft). The glabrous branchlets have minute stipules and tend to be a red-brown colour at the extremities and age to a light-grey colour. The sessile acicular phyllodes have a length of 10 to 25 mm (0.39 to 0.98 in) and are around 1 mm (0.039 in).[1] It blooms from August and produces yellow flowers.[2]

The species was first formally described by the botanist Bruce Maslin as part of the work Acacia miscellany. The taxonomy of fifty-five species of Acacia, primarily Western Australian, in section Phyllodineae (Leguminosae: Mimosoideae) as described in the journal Nuytsia. It was reclassified in 2003 as Racosperma asepalum then transferred back to the genus Acacia in 2006.[3]

It is native to an area in the Wheatbelt and Goldfields region of Western Australia.[2] It is known from areas around Frank Hann National Park, Marvel Loch and Forrestania where it is a part of open Eucalypt woodland communities growing in sandy-loamy soils.[1]
