TEMPERATE HIMALAYA, alt. 7-12,000 ft., from Kashmir to Bhotan, Falconer, 

 &c. 



Stem 3-5 ft., as thick as a goose-quill below. Leaves 12-18 by - in., thinly 

 coriaceous, pale glaucous green, many -nerved; sheath nearly smooth or scaberulous; 

 ligule oblong, membranous. Panicle 6-10 in., inclined or nodding, very soft, shining 

 and silky, pale grey; branches branchlets and very short pedicels capillary, smooth, 

 or minutely scaberulous. Glumes I aud II very thin, smooth, .keels scaberulous, I 

 1-nerved ; II 3-nerved ; III glabrous, hyaline, usually cleft from the upper third into 

 two lanceolate subulate-acuminate lobes ; but the lobes are sometimes irregularly 

 lacerate at the tip ; nerves 5, faint.

 panicle dense or effuse, spikelets %-% in., gl. I and II unequal subulate- 

 lanceolate scaberulous, III = ^-| I tip truncate erose or toothed, awn

TEMPERATE HIMALAYA, alt. 6-10,000 ft. from Kashmir to Sikkim. WESTEEN 

 TIBET, alt. 10-12,000 ft. DISTEIB. Europe, N. and W. Asia. 



Stem 2-5 ft., erect, as thick as a crow-quill or small goose-quill, but some- 

 times very slender. Leaves 12-18 by t*g-i iu > firm ' s 1 " 00 ^ 1 or scaberulous, flat or 

 convolute ; sheaths smooth ; ligule linear-oblong. Panicle very variable in form and 

 composition, erect or inclined, green or purple, rachis and branches scaberulous. 

 Spikelets rarely i in. long, sometimes only in., when the outer glumes are broader ; 

 gl. I and II with scaberulous keels, I usually about 5 longer than II, but sometimes 

 subequal, I 1-nerved and II 3-nerved at the base, but both sometimes 3-nerved ; III 

 glabrous, smooth or faintly scaberulous, faintly 5-nerved; awn very slender, variable 

 in length, rarely longer than its gl. A very difficult plant to define satisfactorily 

 so much do the spikelets vary in size, in the breadth of the empty gls., and in 

 the incision of the top of gl. Ill, which is either rounded and obtusely 2-toothed 

 with an awn in the sinus, or truncate with a terminal awn, or 2-lobed nearly way 

 down with lobes irregularly incised and the awn in the sinus, or finally the awn 

 may be strictly dorsal below the truncate tip. Dr. Stapf, who has revised the 

 whole of the Indian material which I had referred to this species, confirms the 

 above view of its variation, and agrees with me in referring it to the European 

 C. littor<a. 



Var. tartarica ; stem shorter stouter, lesms convolute, panicle strict narrowly
