Discussion

Clarkia modesta occurs mainly in the Inner North Coast Ranges, the San Francisco Bay area, and the South Coast Ranges, from Trinity to Santa Barbara counties, and in the central and southern Sierra Nevada Foothills, from Mariposa to Tulare counties.

Clarkia modesta is one of the parents of the tetraploid species C. similis, from which it differs by having darker pink petals.

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.
