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 similis is known from southwestern California and northern Baja California, Mexico, mainly in the South Coast, Transverse, and Peninsular ranges, from Monterey and San Benito counties in the north to San Diego County in the south. Reports from the Southern Sierra Nevada Foothills in Kern County and the Sacramento Valley in Tehama County are not confirmed.

Clarkia similis is a tetraploid species derived through polyploidization following hybridization between C. epilobioides and C. modesta.
