Eriogonum rubricaule occurs on the eastern half of the pluvial Lahontan Lake basin of northwestern Nevada (Churchill, Esmeralda, Humboldt, Lander, Lyon, Mineral, Nye, Pershing, and Washoe counties). It tends to occur on or near the old lakeshore at the bases of the mountains, where it is infrequent to locally common.

Eriogonum kingii is known only from Elko and northern White Pine counties. It is occasionally cultivated in rock gardens. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
