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.

Clarkia unguiculata is a widely distributed species in California, and occurs throughout much of the southern two-thirds of the state in appropriate woodland habitats.

Clarkia unguiculata is ancestral to C. exilis, C. springvillensis, and C. tembloriensis. It is one of the parents of the tetraploid species C. delicata and may have been involved in the origin of C. heterandra.
