Varieties 2 (2 in the flora). The graceful, upwardly curved branch segments of Eriogonum cithariforme generally are distinctive in older plants, although an occasional individual of E. davidsonii may have this feature. A distinction between E. cithariforme and E. roseum also is troublesome, as in young material the curved branch segments are not always obvious.

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.
