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 modesta occurs mainly in the Inner North Coast Ranges, the San Francisco Bay area, and the South Coast Ranges, from Trinity to Santa Barbara counties, and in the central and southern Sierra Nevada Foothills, from Mariposa to Tulare counties.

Clarkia modesta is one of the parents of the tetraploid species C. similis, from which it differs by having darker pink petals.
