Abronia nana is a highly variable species. Perhaps contraction of the range of A. nana during the Pleistocene left isolated populations that have since diverged. This is especially apparent on the southern edge of the range of the species. In northeastern Arizona, densely tufted plants with very small blades are similar to short-leaved plants of A. bigelovii from north-central New Mexico.
Based on the fruits, the taxon described as Abronia nana var. harrisii S. L. Welsh is A. elliptica.
