Discussion | Caulanthus heterophyllus is a common species distributed from Santa Barbara County southward into northwestern Baja California, Mexico. R. E. Buck (1993) divided the species into two varieties, including one invalidly published, based on flower color, but these are treated here as mere color variants.

Caulanthus major is found in eastern and southern California, Nevada, southeastern Oregon, and Utah. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
