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.
