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 unguiculata is a widely distributed species in California, and occurs throughout much of the southern two-thirds of the state in appropriate woodland habitats. Clarkia unguiculata is ancestral to C. exilis, C. springvillensis, and C. tembloriensis. It is one of the parents of the tetraploid species C. delicata and may have been involved in the origin of C. heterandra.
