Discussion
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.
