Discussion | Camissoniopsis lewisii occurs from Point Dume and the Los Angeles Basin, Los Angeles County, south to Cardon Grande at the northern edge of Baja California Sur. P. H. Raven (1969) determined C. lewisii to be self-compatible and primarily autogamous, and suggested that this coastal Camissoniopsis may have been derived more or less directly from coastal populations of C. bistorta.
