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.) |
Eriogonum temblorense is rare but much more widely distributed than the closely related E. eastwoodianum. In early anthesis, it is difficult to differentiate between the two species, and plants gathered in May at Cottonwood Pass are particularly troublesome, as the first basal leaf blades are often suborbiculate. Those leaves quickly fall away, and the subsequent basal and cauline leaf blades are elliptic. As circumscribed here, E. temblorense is known from six sites in Monterey (Stone Canyon), San Luis Obispo (Cottonwood Pass and Polonio Pass areas), and Kern (Chico Martinez Canyon, Shale Hills, and hills west of McKittrick) counties.
