Discussion

Variety marifolium occurs in widely scattered locations, often on volcanic peaks, in Washington (Yakima County), Oregon (Crook, Deschutes, Douglas, Hood River, Jackson, Jefferson, Klamath, Lane, Linn, and Marion counties), and north-central California (to Shasta County). The variety is more common in the northern Sierra Nevada (Alpine, Amador, Butte, Calveras, El Dorado, Lassen, Mono, Nevada, Place, Plumas, Sierra, and Tuohumne counties) and west-central Nevada (Carson City, Douglas, and Washoe counties). An isolated population is found on the Pine Forest Range of Humboldt County, Nevada
