Discussion

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.

Eriogonum desertorum is a low- to mid-elevation species restricted to central and eastern Elko County, Nevada, and northwestern Box Elder County, Utah. The phase represented by the type is from the valley bottoms and lower foothills, although it extends onto the eastern slope of the East Humboldt Mountains to ca. 2600 m elevation. Such plants tend to have leaf blades that are grayish-tomentose on both surfaces. At higher elevations on isolated desert ranges (Jarbidge, Independent, and Kinsley mountains, where they occur as low as 1950 m) are plants that are smaller in all aspects and tend to have elliptic (rather than oblanceolate to narrowly elliptic) leaf blades; these have been named E. lewisii. Similar plants are in the Grouse Creek Mountains of Utah. As noted above, E. brevicaule var. bannockense occurs in eastern Elko County, where it is widespread and more common than E. desertorum. It is almost always at low elevations in the valley bottoms but can occur on some of the higher, isolated peaks. The leaf blades of var. bannockense are distinctly narrower and mostly longer.
