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.

D. M. Thompson (2005) noted that Diplacus viscidus and D. compactus (as Mimulus viscidus var. compactus) are parapatric and may intergrade in central Mariposa County. The two taxa are distinguished by the presence or absence of dark stripes on the corolla lobe midveins, which are evident even on herbarium specimens. Thompson found that the two remained distinct when grown together in the greenhouse. Diplacus viscidus is known from Amador, Calaveras, Eldorado, Mariposa, Merced, and Tuolumne counties; D. compactus continues south through Fresno, northern Kern, Madera, Mariposa, and Tulare counties.
