Discussion

Variety desereticum is widely scattered in southern Idaho (Bear Lake, Blaine, Custer, and Owyhee counties), southwestern Montana (Park County), and southwestern Wyoming (Carbon, Teton, and Uinta counties) south into northeastern Nevada (Elko County) and northern Utah (Box Elder, Carbon, Daggett, Duchesne, Emery, Juab, Millard, Piute, Rich, Salt Lake, Sanpete, Summit, Tooele, Utah, and Wasatch counties). It is common only in Utah and southeastern Idaho. Variety desereticum is related to var. dichrocephalum, but the two rarely occur together. Late in the season, high-elevation plants can have attractive, bright red leaves. Such plants approach var. porteri in aspect, especially in the Jarbidge, Ruby, and East Humboldt mountains of Nevada. The Deseret sulphur flower is worthy of cultivation.
