Acacia aspera, commonly known as rough wattle,[2] is a species of flowering plant in the family Fabaceae and is endemic to the south-east of continental Australia.

[2][3][4][5] Acacia aspera was first formally described in 1838 by English botanist John Lindley in Thomas Mitchell's journal Three Expeditions into the interior of Eastern Australia,[6][7] based on a collection made near present-day Swan Hill in Victoria during Thomas Mitchell's 1836 expedition.

[4] In 2004, Neville Grant Walsh described subspecies parviceps in the journal Muelleria,[8] and that name, and the name of the autonym are accepted by the Australian Plant Census: Putative hybrids between Acacia aspera and Acacia montana have been recorded in the Bendigo Whipstick region.

[3][2][13] Subspecies parviceps is restricted to Victoria, mainly from sites west of Melbourne, where it grows in open forest.

parviceps is listed as "endangered" under the Victorian Government Flora and Fauna Guarantee Act 1988.
