Discussion
Camissonia integrifolia is known in the flora area from central to southern California, west of the Sierra Nevada.
P. H. Raven (1969) determined that Camissonia integrifolia is a self-compatible tetraploid and autogamous. The species forms sterile natural hybrids with C. strigulosa, to which it is presumably most closely related.
