Eriogonum palmerianum is common and widespread, sometimes becoming locally abundant and even weedy. It is found in the southern Great Basin and Mojave deserts of eastern California eastward through Nevada, southwestern Idaho, and Utah, on to the Colorado Plateau of western Colorado. In Arizona and New Mexico, it occurs mainly in the Sonoran Desert. Occasional collections are difficult to distinguish from E. nidularium, but such confusion usually is not encountered in the field.

Eriogonum gracillimum is found in the Coast, Transverse, and scattered mountain desert ranges in Fresno, Inyo, Kern, Kings, Los Angeles, Madera, Merced, Monterey, Riverside, San Benito, San Bernardino, San Diego, San Luis Obispo, Santa Barbara, and Tulare counties. The species is often common and occasionally even weedy. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
