Discussion | Subspecies 2 (2 in the flora). P. H. Raven (1969) determined Camissoniopsis pallida to be self-compatible and primarily autogamous. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Camissoniopsis intermedia occurs from Lake and Yolo counties (where rare) south in the Coast Ranges of California to the western San Gabriel Mountains, western Riverside and San Diego counties, and south in Baja California to the south end of the Sierra San Miguel; also on Santa Catalina and Santa Cruz islands. P. H. Raven (1969) determined C. intermedia to be self-compatible and primarily autogamous. The species is apparently a tetraploid derived via hybridization between two diploid (2n = 14) species, C. hirtella and C. micrantha.
