FESTUCA BREVIFOLIA, R. Br. in Parry 1st Voy. Suppl. 

 Near Pagosa Peak, Aug. Two forms were distributed : n. 

 175 from 12,000 feet, and n. 176 from 11,500 feet. Both are 

 common on the open alpine slopes and summits; and they 

 have been determined as unquestionable F. brevifolia by our

 occur below the Arctic Circle.
