Acacia auripila, commonly known as the Rudall River myall, [1] is a tree of the genus Acacia and the subgenus Plurinerves that is native to a small area in central Western Australia.
The tree typically grows to a height of 3 metres (10 ft) [2] and has a dense crown with silvery green foliage. It has fissured grey coloured bark and slightly ribbed and glabrescent branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The pungent, glabrescent, leathery and erect phyllodes are straight to slightly curved with a length of 8 to 12 cm (3.1 to 4.7 in) and a diameter of 1 to 1.5 mm (0.039 to 0.059 in) and are striated by many fine parallel nerves. [3] It produces yellow flowers in August. [2]

Miscellaneous new taxa and lectotypifications in Western Australian Acacia, mostly section Plurinerves (Leguminosae: Mimosoideae) as published in the journal Nuytsia .
