Eriogonum umbellatum Torr. var. ramulosum Reveal.  Buffalo Bill's Sulphur Flower.

Guy Gulch, Jefferson County, Colorado. Southwest side of County Road 70 and the gulch, 600 m. northwest of Centennial Ranch, 12.8 km. northwest of the GNIS location of Golden, and 12.7 km. northwest of Buffalo Bill's grave. 39.79777°N, 105.35992°W. WGS 1984 Elev. 2379 m. Outwash delta of small watercourse with smooth brome, snowberry, aspen, and water birch. This collection fits the description of var. ramulosum with the branched inflorescence and bracted branches, whereas other parts of same plant do not. Coll. No. 3078 made nearby was similarly ambiguous as to variety.
