Discussion

Camissoniopsis robusta occurs in coastal San Diego County, California, and coastal northwestern Baja California, south to the vicinity of El Rosario; also on Guadalupe, San Clemente, Santa Catalina, and Santa Cruz (rare) islands. P. H. Raven (1969) determined C. robusta to be self-compatible and primarily autogamous. Based on the intermediate morphology of this hexaploid, Raven suggested that it was derived from two species with which it occurs nearly throughout its rather limited range, the tetraploid C. intermedia (2n = 28) and the diploid C. lewisii (2n = 14).
