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 puniceus occurs in southwestern California and northeastern Baja California. Hybrids are common with D. longiflorus and have been called D. ×australis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
