Discussion

Clarkia franciscana is an endangered species (designated rare by the California Native Plant Society), restricted to serpentine soils in coastal grass and shrub communities. The only known localities for it are the Presidio in San Francisco County, and the Oakland Hills in Alameda and Contra Costa counties.

Geographic distribution and petal color pattern suggest that Clarkia franciscana may be a self-pollinating derivative of C. rubicunda. If true, enzyme studies indicate that the origin is not recent.

Clarkia franciscana is in the Center for Plant Conservation’s National Collection of Endangered Plants.

Clarkia bottae is known from the Outer South Coast Ranges from Monterey and San Benito to Santa Barbara counties, throughout southwestern California, and more sporadically in the southern Sierra Nevada in Fresno and Kern counties. Reports from Del Norte, Madera, and Napa counties have not been verified.

Clarkia bottae is most closely related to C. jolonensis and may be closely related to C. xantiana; all three have 2n = 18, and spontaneous hybrids were formed when C. bottae was grown adjacent to a natural population of C. xantiana.
