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 micrantha occurs from the vicinity of Bodega Bay, Sonoma County, near Lower Lake, Lake County, and near Rio Vista, Sacramento County, south in the Coast Ranges to the Los Angeles Basin and the northern edge of San Diego County; also on San Miguel, Santa Rosa, Santa Cruz, and Santa Catalina islands. The species was introduced, apparently on ballast heaps, at Nanaimo, Vancouver Island, British Columbia (Macoun s.n. in 1893, NMC). It has apparently not persisted in this area. P. H. Raven (1969) determined C. micrantha to be self-compatible and primarily autogamous. Excluded populations are now recognized as C. hirtella, C. ignota, C. lewisii, and C. pallida. Oenothera hirta Link (1821), not Linnaeus (1759), is an illegitimate name that pertains to Camissoniopsis micrantha. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
