Of conservation concern. Eriogonum chrysops is known from five scattered sites in the Skull Creek area of Malheur County. It is no longer considered a candidate for threatened status under the provisions of the Endangered Species Act. However, it still is considered a “threatened” species by the state of Oregon.

Varieties 3 (3 in the flora). Eriogonum deflexum is common and often weedy throughout most of its range. It is an important source of small seed for birds. The reported use of the stem (M. L. Zigmond 1981, as E. insigne) by the Kawaiisu people as a smoking pipe is incorrect; the taxon in point was actually E. deflexum var. baratum. The desert metalmark butterfly (Apodemia mormo deserti) is found in association with E. deflexum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
