A widespread variable species and three principal forms may be recognised: (1) a prickly form associated with rock outcrops in central Australia; (2) a small-leaved more slender form from upper Eyre Peninsula and extending to the Nullarbor Plain; (3) the typical form moderately prickly, relatively large-leaved, widespread in drier Australia.
