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 similis is known from southwestern California and northern Baja California, Mexico, mainly in the South Coast, Transverse, and Peninsular ranges, from Monterey and San Benito counties in the north to San Diego County in the south. Reports from the Southern Sierra Nevada Foothills in Kern County and the Sacramento Valley in Tehama County are not confirmed.

Clarkia similis is a tetraploid species derived through polyploidization following hybridization between C. epilobioides and C. modesta.
