Discussion

Diplacus rattanii occurs mostly in near-coastal localities from Glenn and Lake counties south to Ventura County.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Diplacus pictus is known from Kern and Tulare counties in the Sierra Nevada foothills and Tehachapi Mountains.

Diplacus pictus and D. mohavensis have been treated together as Mimulus sect. Mimulastrum; molecular data (P. M. Beardsley et al. 2004) indicate that the two species are independently derived and that the similarities in corolla morphology are convergent. Diplacus pictus produces cleistogamous flowers in drought conditions.
