Discussion

Clarkia rostrata is known only from the Merced River drainage in the central Sierra Nevada Foothills, including Mariposa, Merced, Stanislaus, and (barely) Tuolumne counties. Because of its very limited distribution, C. rostrata is listed as rare by the California Native Plant Society.

Clarkia rostrata is closely related to C. cylindrica and C. lewisii but can be distinguished readily from both by the conspicuous beak of the capsule.

Clarkia breweri is restricted to dry woodlands and chaparral west of the Central Valley from the San Francisco Bay area into the southern Coast Ranges in Fresno, Monterey, and San Benito counties.
