Like most Acacia species, it has phyllodes rather than true leaves. The sparse and inconspicuous, light green phyllodes shed frequently from the branchlets. the phyllodes are patent to deflexed with a linear shape that is pentagonal-compressed to flat. They are in length and wide and have five nerves. It produces yellow flowers from July to September.

Taxonomy

It was first published by Charles Gardner in 1942, based on a specimen collected by him and possibly also Frank Wise, near Wandagee on the Minilya River in Western Australia, on 31 August 1932. The specific epithet honours Wise.

Distribution

Florabase identifies the IBRA region in which the most samples have been collected from as the Carnarvon region. It is found throughout the Gascoyne and scattered though the Pilbara regions of Western Australia extending eastward into the Northern Territory where it grows in sandy loam soils.
