--><p><i>Eriogonum robustum</i> is restricted primarily to altered andesite soils in west-central <i>Nevada</i>, essentially at the confluence of Carson City, Lyon, Storey, and Washoe counties. There, due to the unusual soil, the plants typically occur in areas without sagebrush but among conifer species usually found at higher elevations. The species is cultivated infrequently and is a food plant for the intermediate dotted-blue butterfly (Euphilotes intermedia).</p>
