Discussion

D. M. Thompson (2005) observed that two forms of Diplacus layneae co-occur from the Yosemite National Park area southward; one of these is recognized here as D. graniticola.

Diplacus angustatus occurs in northern California in the Sierra Nevada and across the Sacramento Valley in the North Coast Range (Lake, Mendocino, and Napa counties); it also is known from one area in northwestern Shasta County and has a disjunct series of populations in Fresno and Tulare counties.
