Discussion

Clarkia dudleyana is a rather widespread species in California, known primarily from the central and southern Sierra Nevada foothills, the Tehachapi Mountain area, the Transverse Ranges, and the Peninsular Ranges, ranging from Tuolumne to Riverside counties, sporadically in the north to Nevada County and in the south to San Diego County

Clarkia dudleyana is morphologically most similar to C. biloba and C. modesta, but molecular data suggest that the relationship is not close. On the basis of chloroplast DNA sequence, C. dudleyana and C. heterandra are closely related.

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.
