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 delicata is known in California only from the Peninsular Ranges, mainly in San Diego County with outliers in Riverside and San Bernardino counties, and in northern Baja California, Mexico. Because of its limited range, it is listed as rare by the California Native Plant Society. It is a tetraploid derived from hybridization between C. epilobioides and C. unguiculata.
