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.) |
Subspecies 2 (2 in the flora). Clarkia mildrediae is closely related to, and may be derived from, C. borealis. Clarkia mildrediae subsp. lutescens is probably the direct ancestor of C. stellata. Clarkia mildrediae differs from C. borealis in petal color and inflorescence habit and from C. stellata in flower size and position of the stigma. On the basis of morphology, chromosome number and pairing, C. mildrediae appears to be one of the parents of the tetraploid species C. rhomboidea.
