Of conservation concern. Eriogonum ripleyi is known only from two areas in Arizona, one near Frazier’s Well in Coconino County and a second in the Verdi Valley area of southeastern Yavapai and extreme northwestern Maricopa counties. The species is worthy of cultivation. Ripley’s wild buckwheat is considered a “sensitive” species in Arizona. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
