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.

Subspecies 2 (2 in the flora). Clarkia mildrediae is closely related to, and may be derived from, C. borealis. Clarkia mildrediae subsp. lutescens is probably the direct ancestor of C. stellata. Clarkia mildrediae differs from C. borealis in petal color and inflorescence habit and from C. stellata in flower size and position of the stigma. On the basis of morphology, chromosome number and pairing, C. mildrediae appears to be one of the parents of the tetraploid species C. rhomboidea.
