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 douglasii occurs in southwestern Oregon and the northern two-thirds of California. Diplacus douglasii is distinct in the complete or nearly complete lack of abaxial corolla lobes. Diplacus brandegeei, D. congdonii, D. kelloggii, and D. traskiae, the other species of sect. Cleisanthus, also show a distinct tendency toward reduction of the abaxial corolla lobes, and all species of the group except D. brandegeei produce markedly elongate corolla tubes.
