Eriogonum polycladon is widely distributed from near Needles, San Bernardino County, California (where not found since the 1930s), eastward to western Texas, and from southern Utah throughout much of central and southern Arizona into western and southern New Mexico. It is found also in the Mexican states of Chihuahua, Durango, and Sonora. It can be locally common and occasionally weedy, especially in southeastern Arizona and southwestern New Mexico. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum ternatum is infrequently encountered in the Coast Ranges of southwestern Oregon (Curry and Josephine counties) and adjacent northwestern California (Del Norte and western Siskiyou counties). A collection from “Dodkin’s Lake” in the Mt. Eddy area of Siskiyou County (Bracelin 455, IND) remains to be confirmed, as this is well to the east of other populations. Some workers have confused this species with E. umbellatum (especially var. humistratum). No doubt the poor representation of this species in herbaria is due at least in part to collectors having assumed that it is some variant of the much more common E. umbellatum.
