Discussion

Eriogonum latens is locally uncommon to rare in the White Mountains of western Nevada (Esmeralda County) and along the eastern slope of the Sierra Nevada in California (Inyo and Mono counties). An isolated population occurs on Waucoba Mountain in the Inyo Mountains. A collection supposedly from Long Valley in Mono County (Noldeke s.n., Jul 1938, CAS) remains to be confirmed as to location.
