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 maculatum is the most common and widespread expression of the E. angulosum complex, being found in Arizona, California, southwestern Idaho, Nevada, northwestern New Mexico, eastern Oregon, western Utah, and southeastern Washington. It is often common to abundant and may even be weedy, especially along roadsides intermixed with other annual wild buckwheats. The swollen bases of the outer tepals readily distinguish the species. The greatest concentrations of the spotted wild buckwheat are found in the Mojave Desert and the Great Basin. A specimen supposedly found on the “Laramie Plains” of Wyoming (Parry s.n., 1882, ISC) is discounted as to location. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
