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.
