spikes are very minutely downy ; the seeds linear-obovate ; the 

 hairs about twice as long as the spikes. A Lapland specimen 

 from Dr. Wahlenberg agrees with them exactly.

Perennial. July. 



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. Spikes solitary, purplish, 

 of many slender Jlowers, whose outermost glume is tipped with 

 a short rough awn. Schrank celebrates this deep-rooted grass 

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

 tous situations, though it renders his ))ath very slippery.
