Discussion

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.
