Discussion | Camissoniopsis ignota is most common in clay fields and slopes at low elevations, but occasional on sandy soil and higher in the mountains in the Coast Ranges and bordering valleys from Yolo County, California, south to the southern end of the Sierra San Miguel, in Baja California, usually away from the immediate coast and barely reaching the margins of the desert. P. H. Raven (1969) determined C. ignota to be self-compatible and primarily autogamous. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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).
