Discussion | Eremothera refracta is known from Esmeralda, southern Nye, and Clark counties in Nevada, Washington County in Utah, south throughout the Mojave and Colorado deserts of Inyo, San Bernardino, Imperial, central and eastern Riverside, and eastern Kern and San Diego counties in California, Mohave, Yuma, and western Pima counties in Arizona, and a single collection well east of normal range has been seen from Hidalgo County in New Mexico (east of Lordsburg, Jones in 1930, POM). P. H. Raven (1969) determined E. refracta to be self-incompatible. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
