Discussion | 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.

Diplacus aurantiacus occurs from southwestern Oregon (Curry County) southward to Santa Barbara County, California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
