Plant floccose-woolly throughout, not stoloniferous; stem 
2’-10' high, simple. Basal leaves oblanceolate or oblong, ob- 
tuse or acutish at the apex, narrowed at the base into short 
petioles, 1’-2’ long, 2’-4” wide; stem leaves linear, acute or 
acutish, erect, the upper gradually smaller; heads in a termi- 
nal subcapitate cluster, or rarely solitary, 24”-3” broad; invo- 
lucre 2’-3” high, woolly at the base, its bracts brownish purple, 
the inner ones of the fertile heads mostly acutish, those of the 
sterile heads mainly obtuse.

spatulate or linear-oblong, obtuse, silvery-woolly on 
both sides, or glabrate and green above, 4”-12” long; 
stem leaves linear and small, few, sessile, woolly; 
heads in a terminal capitate, or seldom somewhat

volucre about 23” high, the bracts of the fertile heads 
dark brownish-green, the inner ones acute or acumi- 
nate, those of the sterile heads lighter, brownish, 
broader and obtuse; achenes glandular.

Columbia. Western plants previously referred to this 
species prove to be distinct. April-Aug.
