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 rattanii occurs mostly in near-coastal localities from Glenn and Lake counties south to Ventura County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
