Eriogonum thymoides is an exquisite species concentrated in three regions of the Pacific Northwest. The first is along the eastern edge of the Cascade Range from near Wenatchee, Washington (Adams, Benton, Chelan, Douglas, Franklin, Grant, Kittitas, Klickitat, Lincoln, and Yakima counties), to near the Dalles in extreme north-central Oregon (Union County). The second is from Baker and northern Malheur counties, Oregon, to Adams, Canyon, and Washington counties, Idaho. A third series of populations is in the Mount Bennett Hills area of Gooding County, Idaho, and just over the borders in Blaine, Camas, Elmore, and Lincoln counties. Staminate plants tend to have yellow flowers that quickly fade after pollen release. Pistillate plants tend to have white to pale yellow flowers that persist and greatly elongate as the achene matures. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum rupinum is the most widespread of the three robust species related to E. racemosum. The Wyman Creek wild buckwheat occurs from the White and Inyo mountains of Mono and Inyo counties, California, eastward in scattered mountain ranges across the central Great Basin of Nevada (Esmeralda, Lander, Lincoln, Mineral, and Nye counties). The bulk of the populations are concentrated in Nye County, Nevada. The Lincoln County location, based on an 1898 collection (Purpus 6263, DS, SD), requires confirmation.
