Discussion | 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.

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.
