glabrous ; IY awn -f in. Pedicelled spHceletsm-d\e, gl. I strongly nerved ; IV 0. 

 A very handsome grass. 



Snbgen. IY. ARTHROLOPHIS. Spikes 2-nate digitate or subpauiculate, 

 on a common peduncle arising from a spathiform sheath ; joints few or 

 many, clavat or bucciniform (slender in A. tristis), tips cupular with 

 toothed margins. Sessile spiJcelets dorsally compressed ; gl. I not awned, 

 margins inflexed, keeled; II dorsally keeled, awned or not; III hyaline ; 

 IV small. 2-fid with an interposed awn, or reduced to a simple awn. 

 Pedicelled spikelets usually unlike the sessile ; gl. I awned or not. A 

 heterogeneous assemblage. 



* Joints of spikes and pedicels of upper spikelets rather slender ; gl. II 

 of sessile spikelet not awned. 



9. A. tristis, Nees ex Hack. Monogr. Androp. 439; spikes 3-6 un- 

 nnequal stipitate or subsessile on the peduncle, gl. I of sessile spikelet 

 lanceolate deeply depressed between the thickened sides, IV very narrow 

 2-fid. 



TEMPERATE WESTERN HIMALAYA, alt. 8-1000 ft., from Kashmir to Garwhal. 



Stems 2-3 ft., compressed, tufted on a stout short or creeping rootstock, slender 

 or rather stout, erect or geniculate below, branching above ; nodes glabrous. Leaves 

 610 by ^5 in., narrowly linear, sraberulous, rather rigid, hairy at the base ; lower 

 sheaths broad, compressed ; ligule oblong, membranous. Spikes 1-3 in., livid green ; 

 peduncle 2-6 in., spathe very narrow ; joints and pedicels = f the sessile spikelet, 

 hardly clavate, shortly ciliate. Spikelets loosely imbricate, sessile in., very narrow ; 

 callus hairs very short; gl. I more or less scaberulous margins broadly inflexed ; 

 II narrowly oblong, apiculate, ciliate, keel subscaberulous ; III lanceolate, 2-nerved, 

 ciliate ; IV awn short or ; palea minute, quadrate. Pedicelled spikelets as long as 

 the sessile, gl. I 3-7 -nerved; II 1-5-nerved; III hyaline; IV 2-fid and mucrouate 

 or 0, paleate or not. 



** Joints of spikes and pedicels of upper spikelets clavate or buccini- 

 form.

 open ; ligule oblong, obtuse, chartaceous, Inflorescence subpanicled ; peduncle 

 2-4 in., filiform, puberulous, sheathed almost up to the spik'es. Spikes --1 in., very 

 unequal in each fascicle, very shortly stipitate, hairs or cilia rigid setiform brownish, 

 joints and pedicels half as long and as broad as the sessile spikelets, cuneately cam- 

 panulate, base narrow, dorsally rounded, glabrous or scaberulous, sides ciliate with 

 long hairs. Sessile spikehts i-| in. ; callus conical, rigidly bearded; gl. I deeply 

 channelled dorsally, keels scabrid above the middle, thickened below, nerves 2-nate
