Discussion | Diplacus graniticola occurs in the Sierra Nevada from Tuolumne County to northern Tulare County. These plants previously were identified within D. layneae, with which they are partially sympatric; where these two occur together, D. layneae often grows in granite-derived sand and gravel immediately adjacent to the granite rock habitat of D. graniticola.

Diplacus constrictus is endemic to Kern, Los Angeles, Tulare, and Ventura counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
