|discussion=<p>Variety elongatum occurs in the Coast and Transverse Ranges of southeastern California from Monterey and San Benito counties southward to Mexico. The elongate, upright flowering stems and inflorescence branches often persist for several years with new stems produced annually. The long, “leggy” habit is not particularly attractive in the garden even though the variety is occasionally grown as an ornamental. The long-stem wild buckwheat is heavily visited by honey bees in some areas and is the host plant of the Gorgon copper butterfly (Gaeides gorgon). J. B. Romero (1954) reported that the variety was used by Native Americans to treat high blood pressure, and E. W. Voegelin (1938) mentioned that the stems were roasted and the resulting juice was used as a chewing gum. Care should be taken not to confuse fragmentary specimens of the annual <i>Eriogonum roseum</i> with the perennial <i>E. elongatum</i>.</p>
