Eriogonum rupinum is the most widespread of the three robust species related to E. racemosum. The Wyman Creek wild buckwheat occurs from the White and Inyo mountains of Mono and Inyo counties, California, eastward in scattered mountain ranges across the central Great Basin of Nevada (Esmeralda, Lander, Lincoln, Mineral, and Nye counties). The bulk of the populations are concentrated in Nye County, Nevada. The Lincoln County location, based on an 1898 collection (Purpus 6263, DS, SD), requires confirmation.
