should have taken Jacquemont's mss. specific name for this species, had it not been 

 that it was taken up by Munro for another plant. (See Elymus sibiricus.) 



5. A. Thomson!, Hook. /. ; lower sheaths villous, spikelets 

 many ovoid erect, glumes erecto-patent, I and II ovate-oblong acute 

 or acuminate 5-7-nerved margins hyaline, flg. gls. silkily villous ovate- 

 lanceolate narrowed into an erect slender awn twice as long as the gl. or 

 shorter. 



WESTERN HIMALAYA, alt. 10-12,000 ft., from Kunawur and Piti, Jacquemont, 

 Thomson, to Garwhal, Strachey <jf Winterbottom, Duthie. 



Stem 2-3 ft., stout or slender, densely tufted. Leaves narrow, margins flat or 

 involute, upper glabrous, lower more or less hairy. Spikes 3-6 in., rachis pubes- 

 cent on the margins or all over. Spikelets ^^ in. without the awns, 5-7 -fld. ; 

 internodes of rachilla short, scaberulous; gls. I and II with scaberulous nerves; 

 II sometimes toothed at the tip and mucronate ; flg. gls. faintly nerved ; keels of 

 palea ciliate. 



** Spikelets awnless (or very shortly awned in Indian specimens). 



6. A. repens, Beauv. Agrost. 102 (the Indian form) ; stem very 

 slender, leaves narrow, spike slender, spikelets rather distant 5-6-fld. 

 oblong quite glabrous, gls. I and II unequal linear or linear oblong 

 obtuse acute or notched at the tip strongly 3-5-nerved margins scarious,

Stems 1-2 ft., densely tufted at the base, erect or ascending. Leaves flat, or 

 convolute when dry, -$$-% in. broad, smooth, glabrous or puberulous above. Spikes 

 3-6 in., erect, rachis slender, margins of hollows quite glabrous. Spikelets 4-f in., 

 very pale, internodes of rachilla short nearly glabrous ; glumes rather spreading, 

 calli quite glabrous ; keels of palea smooth. I follow Munro, Clarke and Hackel 

 (in litt.) in referring this species to A. repens, though it differs much from Boissier's 

 description of that species in the leaves not being scabrid, in the unequal glumes, 

 of which I and II are much shorter than the flg. and in the latter not being 

 lanceolate. 



7. A. dentatum, Hook.f.; root creeping, leaves flat, spike slender, 

 spikelets imbricating 3-5- fld. quite glabrous or sparsely pubescent, gls. 

 I and II large subequal oblong obtuse obliquely truncate nnidentate or 

 mucronate rarely awned very strongly 7-9-nerved, fl. gls. linear-oblong 

 obtuse acute or acuminate strongly 5-nerved above the middle.

Habit of A. repens, to which specimens have been referred by Munro and 

 Clarke, but the spikelets (which are green or purplish) are closely imbricating, the 

 margins of the hollows of the rachis scaberulous or ciliolate, the empty gl. much 

 larger broader and as long as the flg. or nearly so and many-nerved. Under No. 

 12,432 of Duthie's Kashmir collections I find along with typical A. dentatum, and
