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.

Subspecies 2 (2 in the flora).

Clarkia tembloriensis is derived from C. unguiculata and is closely related to C. exilis and C. springvillensis. Hybrids between the subspecies of C. tembloriensis have low fertility and the two taxa are rarely found together.
