Discussion | Diplacus mephiticus occurs in eastern California and west-central Nevada. Various synonyms treated here are in agreement with D. M. Thompson (2005). Mimulus coccineus (mostly from Eldorado to Tulare counties, California, and, apparently, including Eunanus angustifolius Greene from Mt. Rose, Nevada) includes relatively small, tufted plants at high elevations with relatively small calyces and relatively small, dark red-purple, strongly bilabiate corollas with prominently exserted stamens. Mimulus densus (mostly in Nevada and in Lassen, Nevada, and Plumas counties, California) includes taller plants at lower elevations with a strong tendency to produce populations with all individuals with larger, yellow, nearly regular corollas with more nearly included stamens. Typical Diplacus mephiticus has moderate-sized plants at medium elevations with magenta, bilabiate corollas. The specific epithet mephiticus alludes to the musky odor of the plants; this has also been noted in plants of Mimulus coccineus and M. densus. Diplacus nanus, in which D. M. Thompson (2005) included D. mephiticus as a variety, apparently does not produce a mephitic odor. Diplacus cusickii also produces a mephitic odor (W. L. Ezell 1971). The later homonym Mimulus angustifolius (Greene) A. L. Grant 1925, not Hochstetter ex Richard 1850, based on Eunanus angustifolius, pertains here.

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.
