Root of numerous, very strong, downy fibres. Stems and leaves 

 furrowed, roughish with minute bristles, rigid, 4 or 5 inches high, 

 remaining bleached through the winter. SyoiA-es solitary, purplish, 

 oF many slender Jlowers, whose outermost glume is tipped with

 as a safe support to the hands of the alpine botanist, in precipi- 

 tous situations^ though it renders his ])ath very slippery.
