Stems 6-18 in., densely tufted, rather stout, sometimes slender. Leaves 1-3 in., 

 flat or convolute; lignle short. Panicle 1-2 ia., branches very short, scaberulous. 

 Spikelets purplish ; gl. I and II membranous, nearly smooth ; III ^-J shorter than 

 II, minutely scaberulous^ strongly 4-nerved, callus hairs short la^. — In Jacquemont's 

 and, all other specimens in Herb. Kew, the panicle is oblong spioiform, with very 

 short branches, and not as represented in the figure cited of CalamagrosUs hold- 

 /orifjjs which is taken from a specimen collected by Jacquemont and in which the 

 panicle is quite open. The glumes I and II are represented in the same plate as 

 narrowly lanceolate tapering to a point, and scabrid, none of which characters agree 

 with these specimens. Lastly, the date of collection is given as 1830, and that of the 

 Kew specimen 1831. Nevertheless having regard to the great variability of these 

 alpine grasses, I am disposed to think both referable to one species.
