Discussion

Clarkia mosquinii is known only from a small area in the Feather River drainage at the northern limits of the Sierra Nevada range in Butte and (barely) Plumas counties; it is listed as rare by the California Native Plant Society.

Clarkia mosquinii is closely related to C. borealis and may be a derivative of that species with a reduced chromosome number. In addition to chromosome number, they differ in geographical distribution and shape of the buds, which are blunt at the tip in C. mosquinii and acute or acuminate in C. borealis. Clarkia mosquinii is also closely related, and probably ancestral, to two species with 2n = 10, C. australis and C. virgata, which have more southern distributions.

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.
