Discussion

Populations of Diplacus johnstonii occur in Los Angeles, Riverside, San Bernardino, Santa Barbara, and Ventura counties. The populations in northwestern Los Angeles, Santa Barbara, and Ventura counties were noted by D. M. Thompson (2005) to be intermediate between D. constrictus and D. johnstonii.

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.
