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 australis is found in the foothills of the central Sierra Nevada range, from Calaveras, Madera, Mariposa, and Tuolumne counties, and has been designated as rare by the California Native Plant Society. Clarkia australis is morphologically very similar to C. virgata and, based on its more southern distribution, may be derived from it. They are most readily distinguished morphologically by the narrower leaves of C. australis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
