Discussion | 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.

Clarkia virgata is known primarily from El Dorado to Tuolumne counties in the north-central Sierra Nevada range, with scattered collections to Mariposa and Yuba counties. Clarkia virgata is very similar to C. mosquinii and C. australis and is probably derived from the former through chromosome reduction in number and rearrangement and may be ancestral to the latter, which differs in chromosome arrangement. Experimental hybrids in all combinations have very low fertility. The three species are difficult to distinguish morphologically but replace one another ecogeographically with C. australis in the south and C. virgata in the middle with non-overlapping distributions. Other than geographical distribution, C. virgata is usually distinguishable from C. mosquinii by having narrower petal blades and from C. australis by having broader leaves.
