w North America, nw Mexico.
Species 2 (2 in the flora).
Athysanus and Heterodraba are strikingly similar in almost all aspects except for the differences in the key below. Although R. C. Rollins (1993) mentioned nothing about their relationship, he keyed them out in one couplet. Their species are more closely related to each other than to other Brassicaceae. In my opinion, the recognition of two independent monotypic genera obscures their sister phylogenetic relationship. Both genera were described simultaneously by Greene, and since W. L. Jepson (1901) transferred the type of Heterodraba to Athysanus, the latter name has nomenclatural priority.
