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).

Eriogonum androsaceum is common in the high northern Rocky Mountains in southern Alberta and northwestern Montana (Glacier, Lincoln, Park, Pondera, and Teton counties). It is clearly related to E. flavum but is sufficiently distinct to merit recognition as a species. It is seen occasionally in cultivation but deserves more horticultural attention. A decoction of the rock-jasmine wild buckwheat was used in sweatbaths for rheumatism, and for internal pain by the Thompson Indians of British Columbia (E. V. Steedman 1930). Interestingly, Steedman indicated also that a strong decoction of the plants was used for syphilis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
