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.
