Deyeuxia."] CLXXIII. GRAMINE.E. (J. D. Hooker.) 267 



pale green, shining; gl. I and II quite smooth on the sides and keels ; ! III hyaline, 

 lateral awns more than half as long as the gl., dorsal awn inserted above the base 

 capillary, about twice the length of the gl. ; rachilla short ; callus hairs scanty 

 short. 



4 D. compacta, Munro ex Duthie Grass. N.W. Ind. 30 (name 

 only] ; stem short, leaves very narrow, panicle open or spicit'orm, spikelets 

 ^ in., gl. I and II subequal oblong-lanceolate apiculate, III truncate tip 

 erose, palea nearly as long as its gl., awn basal, hairs of callus short.

WESTEEN TIBET, Jacquemont ; Nubra valley, alt. 14-16,000 ft., Thomson; N. 

 of Kumaon, alt. 15,000 ft., Strachey fy Winterb. (Deyeuxia, No. 1). 



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

 flat or convolute ; ligule short. Panicle 1-2 in., branches very short, scaberulous. 

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

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

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

 short branches, and not as represented in the figure cited of Calamagrostis hold' 

 formis 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.

 gls. I and II unequal lanceolate smooth., Ill truncate tip 4-mucronate,

 - longer than II, both 1-nerved, acuminate; III about half as long as I, hardly 

 scaberulous, neives 4, strong; awn basal, not twice as long as the gl., erect.
