Varieties 2 (2 in the flora). Eriogonum gracile is a highly variable species. The low, spreading plants from the mountains of coastal central California with 2–3 mm involucres and (usually) yellowish flowers differ from the more erect plants represented by the type collection, which have 1.8–2 mm involucres and white flowers. Such plants are found mainly farther south, in the Mt. Diablo and Mt. Hamilton areas of Alameda, Contra Costa, and Stanislaus counties. Some populations of E. gracile from the Inner Coast Ranges of eastern San Luis Obispo County are slightly different from the norm and the epithet leucocladon has been adopted in some local floristic treatments to account for them. However, the type of E. leucocladon does not seem to be this phase. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum scopulorum is known only from a few scattered locations in the Wallowa Mountains of Wallowa County, Oregon, and in Adams and Idaho counties, Idaho. While rare, and of concern to the U.S. Forest Service, it is not considered a “sensitive species,” given its remote location and lack of any immediate threat. The cliff wild buckwheat is worthy of cultivation as a rock garden plant. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
