rymbs ; involucre hemispherical; the outer scales rather loosely apprcssed, 
herbaceous, smooth, linear-spatulate, acute ; inner ones lanceolate, with char-

lanceolate, sessile or short-stalked ; uppermost ones linear, all of them acute ; 
heads large, peduncled, single or 3-5 together at the ends of the branches ; 
scales of the hemispherical involucre rather large, loosely imbricated in about

nia. Valleys and canons from the West Humboldt Mountains to the AYah- 
satch ; 6-8,000 feet elevation ; July-September. (504.) Another form 
with rather broad thickish leaves, mostly somewdiat scabrous on the upper 
surface, was collected on the Virginia and West Humboldt Mountains, at
