Discussion | 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.) |
Clarkia prostrata, like C. davyi, occurs only on coastal bluffs and adjacent low elevation pine forests along the Pacific coast, and in this case only in the California Central Coast Subregion in Monterey, Santa Barbara, Santa Cruz, and San Luis Obispo counties. Clarkia prostrata is a hexaploid that combines the tetraploid genome of C. davyi and the diploid genome of C. speciosa. Clarkia prostrata is morphologically and ecologically very similar to C. davyi but can usually be distinguished by its larger flowers with a spot on each petal. It differs from C. speciosa by having smaller flowers with the stigma not exserted beyond the anthers. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
