Eriogonum artificis is known from a single location near Frisco in Beaver County. Care must be taken not to confuse Kaye's wild buckwheat with glabrous forms of E. spathulatum that occur nearby. The flowers of E. artificis are usually pale yellow, but occasionally plants are found with cream-colored and distinctly yellow flowers.
