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 springvillensis is a rare species known primarily from the vicinity of Springville in Tulare County, with one ambiguous collection from Kern County. Due to its very limited distribution, C. springvillensis is listed as rare by the California Native Plant Society. It is derived from C. unguiculata and is closely related to C. exilis and C. tembloriensis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
