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.
