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 pictus is known from Kern and Tulare counties in the Sierra Nevada foothills and Tehachapi Mountains. Diplacus pictus and D. mohavensis have been treated together as Mimulus sect. Mimulastrum; molecular data (P. M. Beardsley et al. 2004) indicate that the two species are independently derived and that the similarities in corolla morphology are convergent. Diplacus pictus produces cleistogamous flowers in drought conditions. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
