Discussion | 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.) |
Subspecies 3 (3 in the flora). Clarkia biloba is most closely related to C. lingulata, which is derived from C. biloba subsp. australis. Some populations of C. biloba subsp. brandegeeae (originally described as a form of C. dudleyana) are morphologically very similar to some individuals of C. dudleyana but the two taxa are separated geographically, have different chromosome numbers, and hybrids between them are sterile.
