Discussion | Clarkia jolonensis is known only from Monterey County, mainly in the Outer South Coast Ranges. It is scarcely distinguishable morphologically from C. bottae except for seed color, but attempts to produce hybrids have been unsuccessful. Although in describing C. jolonensis Parnell suggested that its range did not overlap with that of C. bottae, the ranges in fact overlap extensively in Monterey County.

Subspecies 2 (2 in the flora). Clarkia borealis is closely related, and possibly ancestral, to C. mildrediae. The two species can be distinguished most readily by the degree of curvature of the inflorescence and the petal color. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
