 base chiefly. Leaves 3-8 by i- in., flat, finely acuminate, nearly smooth or 

 scaherulous above ; sheaths smooth ; ligule very short. Spike 3-8 in. ; rachis 

 glabrous or nodes pubescent. Spikelets $-% in. exclusive of the awns, green, im- 

 bricating ; gl. I and II subequal, strongly 3-5-nerved, smooth or scaberulous, rarely 

 toothed on one side towards the tip; fl. gls. lanceolate, more or less distinctly 

 notched at the tip, 5-nerved, from nearly glabrous to scaberulous, and with minutely 

 ciliolate nerves ; awn - in. ; keels of obtuse palea strongly shortly ciliate. Grain 

 oblong, dorsally compressed, concavo-convex, tip villous.

 collateral unequal subulate-lanceolate 1-3-nerved aristately acuminate, II 

 nearly as long as the lowest fl. gl., fl. gls. lanceolate more or less silky 5- 

 nerved tip notched towards the subulate or shortly awned tip. Steud. Syn. 

 Gram. 350; Duthie Grass. N.W. Ind. 46. E. jenisseensis, Turc. in Bull. 

 Soc. Nat. Mosc. xxix. (1856) i. 64. 



KASHMIR & KUNAWUR, alt. 8-12,000 ft., Jacquemont, Clarke, &c. WESTERN 

 TIBET, alt. 10-14,000 ft., Thomson, &c. Laptal (N. of Kumaon) alt. 14,500 ft., 

 Strachey 8f Winferbottom. DISTKIB. Turkestan, Siberia. 



Stem 2-5 ft., stout or slender. Leaves 6-12 in., flat and ^-5 in. broad, or 

 narrow with margins involute, smooth or scaberulous. Spike 6-8 in., variable in 

 breadth ; rachis stout, pubescent sparsely villous or nearly glabrous. Spikelets % in. 

 long; gl. I and II very narrow, 1- rarely 3-nerved ; fl. gls. notched at the base of 

 the awn on both sides, 5-nerved, rarely almost glabrous ; keels of obtuse palea 

 stoutly ciliate. 



4. E.? Thomson!, Hook. f. ; spike stout strict, spikelets 2-3-nate 

 densely crowded sessile and pedicelled, glumes all scarious (in frt.) broadly 

 oblong or ovate-oblong with hyaline margins or very stout midrib and 7-9 

 fainter lateral nerves suddenly ending in a short stout awn. 



WESTERN TIBET ; Danskar, in Piti, alt. 13,000 ft., Thomson. 



Stem 12-14 in., very stout, erect. Leaves 3-6 in., narrow, convolute, coriaceous, 

 smooth, finely acuminate, subpungent ; sheaths broad, striate ; ligule very short. 

 Spike 3-4 in., rachis very stout, smooth or subsilky on the angles. Spikelets 3-^ 

 in., glabrous or faintly pubescent ; rachilla very short and stout; glumes snbpubes- 

 ceut, usually broadly notched below the awn often unequally, margins ciliolate, 7-9- 

 nerved; palea very broad, pubescent, ciliate, 2-lobed, keels unequal more or less 

 ciliate. Grain free, concavo-convex, top glabrous. I have seen only two specimens 

 of this plant, which resembles a wheat more than an Elymus, from which latter 

 genus it diflers in the free grain with a glabrous tip; both specimens are far 

 advanced, and I doubt the grain being in a normal condition.
