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 davyi is ecologically restricted, mainly growing along the Pacific coast on bluffs and grassy stabilized sand dunes, rarely farther inland. Its range extends from Humboldt and (barely) Del Norte counties in the north through all coastal counties to Santa Barbara County in the south, including Santa Rosa Island.

Clarkia davyi is morphologically similar to the polytypic South American tetraploid C. tenella and appears to be one of the parental species of the hexaploid C. prostrata.
