Discussion
Variety humilius is the common expression of the species in the northern Great Basin, extending from Mono and Inyo counties, California, northeast across Nevada (Carson City, Churchill, Douglas, Elko, Esmeralda, Eureka, Humboldt, Lander, Lyon, Mineral, Nye, Pershing, Storey, and Washoe counties). Plants are usually scattered and the variety is rarely a local dominant; it often grows in volcanic soils. Variety humilius is worthy of cultivation; the large shrubs, when in full flower, can be spectacular.
