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.) |
