Discussion

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.

Clarkia exilis is of limited distribution, known primarily from the southern Sierra Nevada Foothills and Tehachapi Mountain area in Kern and Tulare counties, with unverified reports from Fresno, San Luis Obispo, and Ventura counties. It is listed as rare by the California Native Plant Society.

Clarkia exilis is derived from C. unguiculata and is closely related to C. springvillensis and C. tembloriensis.
