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 puniceus occurs in southwestern California and northeastern Baja California. Hybrids are common with D. longiflorus and have been called D. ×australis.
