 nerved, villous-tomentose on both surfaces ; upper leaves gradually smaller ; 

 heads in a capitate terminal corymb ; involucre woolly at the base, the scales 

 brownish, with paler crisped and scarious shining tips, more acute in the 

 fertile than in the sterile heads. — Arctic America to Labrador and the Sas- 

 katchewan. Wet mountain-side in the Havallah range, Nevada ; 7,000 feet

 less stems ; flowering stems 2-8' high, simple ; leaves 6-9" long, white- 

 tomentose, the radical ones spatulate, the cauline linear ; heads 3-7, nearly 

 sessile in capitate clusters ; involucre somewhat woolly at the base, the scales
