 scaberulous above ; sheaths smooth j ligule ve^-y short. Spike 3-8 in. ; rachis 

 glabrous or nodes pubescent. Spikelets 3-J in. exclusive of the awns, green, im- 

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

 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. B. jenieseensis, Turo. in Bull.

 Btrachey S[ Winlerbottom. — Distkib. Turkestan, Siberia. 



Stem 2-5 ft., stout or slender. Leaves 6-12 in., flat and ^-J 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 i 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.? Thomsoni, Hooh. f. ; spike stout strict, spikelets 2-3-nate 

 densely crowded sessile and pe'dioelled, glumes all scarious (in frt.) broadly 

 oblong or ovate-oblong with hyaline margins or very stont 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 ^-^ 

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

 cent, 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 differs in the free grain with a glabrous tip; both specimens are far 

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