Eriogonum nidularium is common and widespread, sometimes becoming weedy, especially along roadsides. It is basically a species of the Great Basin and the Mojave Desert, found mainly in eastern California and Nevada, extending into northwestern Arizona, southwestern Idaho, southeastern Oregon, and southwestern Utah. The numerous, often distinctive, incurved inflorescence branches resemble a bird nest, as reflected in the common name.

Of conservation concern. Eriogonum molestum is infrequent to occasionally common in the San Bernardino (San Bernardino County) and San Jacinto (Riverside County) mountains, and in scattered mountain ranges of San Diego County, California. It is easily confused with the perennial E. nudum var. pauciflorum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
