Discussion | Diplacus bicolor is endemic to Fresno, Kern, and Tulare counties in the southern Sierra Nevada. The combination D. whitneyi (A. Gray) G. L. Nesom is illegitimate, as Mimulus whitneyi A. Gray 1886, is a replacement name based on Eunanus bicolor A. Gray 1868. Diplacus bicolor, D. bigelovii, D. constrictus, D. graniticola, D. layneae, and D. thompsonii appear to be closely related species, sometimes intergrading where sympatric. Plants of each species often produce flowers at all nodes and have dark magenta corollas with nearly regular to weakly bilabiate limbs and villous vestiture. Specimens of each species dry to a dark color. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Diplacus fremontii occurs from Monterey and San Benito counties south to San Diego County, east to Kern County and adjacent Inyo County, and in Baja California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
