" Culm 2 to 3 feet high, smooth, leaves of culm 3 or 4, rigid, erect, 

 narrow, scabrous, 3 to 6 inches long; ligule short and truncate; spike 

 slender, erect, cyclindrical 3 to 5 inches long ; commonly in slender 

 specimens there is but one spikelet at each joint of the rachis, in 

 stronger ones the lower spikelets are in pairs and the upper ones 

 single ; frequently some of the spikelets have three glumes, even some 

 of the double ones, i.e., one glume on each side and one in front. 

 Spikelets one to three-flowered, empty glumes linear-lanceolate, rigid, 

 scabrous, mostly three-nerved, 3 to 4 lines long, and running into an awn 

 as long or longer ; flowering glumes oblong-lanceolate, punctulate below 

 and scabrous above, 4 or 5 lines long, with an awn as long or longer, 

 five-nerved ; palet equalling the glume, obtuse." ( Vasey.*) In tufts on 

 dry hillsides and in hollows, at and around, Kamloops, B.C., 1889. 

 (Macoun.'} " These specimens differ from the type only in their pube- 

 scent lower sheathes and leaves. Axis of spike articulated." (Scribner.)
