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.

Varieties 5 (5 in the flora).

The capitate inflorescence and basal leaves of Eriogonum kennedyi distinguish it from the closely related E. wrightii. At higher elevations in the Transverse Ranges of California, the distinction between E. kennedyi var. kennedyi and E. wrightii var. subscaposum is not always clear, especially near the summit of Mt. Pinos. At lower elevations in the San Bernardino Mountains, in more arid habitats, the distinction between E. kennedyi var. austromontanum and E. wrightii var. subscaposum also is blurred. For the most part this intergradation seems to be associated with a reduction in the length of the inflorescence in depauperate expressions of var. subscaposum and not a result of hybridization. The extreme reduction seen in E. wrightii var. olanchense exemplifies the general trend in the California expressions of that species toward depauperate forms. It is felt that E. kennedyi itself is an established segregate that owes its origin to E. wrightii. Members of the species are food plants for Bauer’s dotted-blue butterfly (Euphilotes baueri) and the Ord Mountain metalmark butterfly (Apodemia mormo dialeuca).
