Discussion

Clarkia lingulata is listed as endangered by the State of California, known from only a few populations in Merced River Canyon, Mariposa County. It is derived from C. biloba subsp. australis, from which it can be distinguished morphologically by its narrower, unlobed petals; the two taxa also differ in chromosome number, and form only highly sterile hybrids.

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.
