Discussion | Brickellia nevinii appears to be an incarnate form of B. microphylla. The variability in indument often makes distinguishing these species problematic. Brickellia nevinii is sometimes reported to intergrade with B. californica. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
