Discussion | Clarkia dudleyana is a rather widespread species in California, known primarily from the central and southern Sierra Nevada foothills, the Tehachapi Mountain area, the Transverse Ranges, and the Peninsular Ranges, ranging from Tuolumne to Riverside counties, sporadically in the north to Nevada County and in the south to San Diego County Clarkia dudleyana is morphologically most similar to C. biloba and C. modesta, but molecular data suggest that the relationship is not close. On the basis of chloroplast DNA sequence, C. dudleyana and C. heterandra are closely related. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Clarkia rubicunda is known from the central coast of California, from Contra Costa and Marin counties south along the coast and foothills to northern San Luis Obispo County. Clarkia rubicunda is probably a derivative of C. amoena and may be ancestral to C. franciscana. Clarkia rubicunda is distinguishable from some populations of C. amoena only by the absence of a red spot or group of spots near the middle of the petal and the presence of a red area at the base of the petal. Clarkia rubicunda can be distinguished from C. franciscana by the position of the stigma and size and shape of the petals. All three species differ in chromosome arrangement and hybrids are highly sterile. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
