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.
