Beatley's Buckwheat

Beatley buckwheat, Eriogonum rosense var. beatleyae, Nevada, White Mountains, Sugarloaf, Queen Valley - Owens Valley drainage, elevation 2673 m (8770 ft).This rare variety is endemic to west-central Nevada at elevations up to about 2800 meters (9200 feet), usually on clay soils derived from volcanic materials. It's somewhat more common sibling, var. rosense, is found a little farther west in the Sierra Nevada and adjacent Great Basin ranges, at higher elevations up to about 4000 meters (13000 feet), usually on rocky or gravelly, non-clay soils.Both varieties are easily recognized by their combination of densely glandular, non-cobwebby stems and bright yellow flowers. The var. beatleyae has longer leaves with broader, rounder blades, and somewhat larger flowers, than var. rosense.Eriogonum rosense is named for its type location on the summit of Mount Rose between Reno and Lake Tahoe. The var. beatleyae is named for Janice C. Beatley (1919-1987), ecologist and botanist on the Nevada Test Site.
