Diplacus graniticola
Diplacus linearis
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.

The coastal Diplacus linearis (as Mimulus bifidus subsp. fasciculatus) was allied by F. W. Pennell (1947) with the Sierran D. grandiflorus (as M. bifidus subsp. typicus) as a narrower-leaved and smaller-flowered subspecies; see discussion concerning its distribution under 40. D. grandiflorus. The two were considered synonymous by D. M. Thompson (2005). They are distinct in geography, ecology, and morphology.
