spatulate-obovate or spatulate, obtuse to acutish, about 1™ long, 
rarely more, densely tomentose on both sides; cauline leaves narrowly 
oblong, obtusish to acute: heads very small, about 4™™ high, sessile, 
$to 8 in a close glomerate cluster: involucres very woolly, in the 
pistillate heads campanulate-cylindrical ; bracts of pistillate heads 
narrow, the inner acute, the scarious portion dark greenish-brown, the 
outer much shorter, broader, woolly to the tip or almost so; in the 
staminate heads the scarious portion also dark greenish-brown, oblong- 
obovate, very obtuse, spreading and becoming reflexed with age: pap- 
pus of staminate heads clavellate. 
This species differs from all other related forms in that the short outer 
bracts are woolly to the tip. From A. umbrinella, its nearest relative, it 
differs in its much darker bracts, and acute pistillate ones. It inhabits dry 
open hillsides at subalpine stations. ~
