Acacia victoriae ssp. arida Pedley was described in Austrobaileya 1:271 (1979). It is distinguished from the type by its soft spreading hairs 0.2-0.3 mm long. Some of these specimens have much broader penniveined phyllodes but are very variable. Pedley also claimed there is some ecological separation. A number of South Australian collections have been so named but as many intermediates occur its distinction in South Australia needs more study. When plotted most of the collections so identified are north and east of Lake Eyre.
