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 5 (5 in the flora). Clarkia amoena is closely related to C. rubicunda, which differs morphologically mainly in the color pattern of the petals. Petals of C. amoena have a conspicuous red spot or group of small red spots or marks near the middle, whereas those of C. rubicunda have a red area at the base and are not spotted near the middle. The areas of distribution of the two species barely overlap in California just north of San Francisco Bay, and C. rubicunda could be considered a southern geographical race or subspecies of C. amoena were it not that their readily formed hybrids are sterile due to chromosomal rearrangement. Clarkia amoena is one of the parent species of the allotetraploid C. gracilis. Intermediates between subspecies are frequent.
