Discussion | Diplacus tricolor occurs in northwestern and south-central Oregon and from there across a disjunction to central California as far as Kern County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
