much longer than the spike, acute ; sheaths striate, lower lax j lignle orate, obtuse. 

 Spikelets 1-3, remote, l-4.fld. ; gl. I and II 1-nerved, gl. I shorter than II j fig. gls. 

 1-4 with 1-2 empty above them, linear-oblong, 3-nerved ; lateral lobes with capillary 

 awns ; median awn twisted at the base ; palea oblong, keels ciliolate. Anthers 

 minute, subglobose. Grain narrowly linear, cylindric.

 ^i in., gl. I lobed on one side, II narrowly lanceolate acuminate entire or 

 notclied below the tip. III villous at the basCj awn twice as long as the gl. 

 or longer.

Stem 8-18 in. Leaves 6-10 in. Spikes 2-12 in., stout or slender. Spikelets 3, 

 close or distant, 4-10-fld. ; gl. I lanceolate, acuminate or aristate, broadly lobed on 

 one side, the lobe sometimes detached ; II much longer, lanceolate, acuminate or 

 2-toothed with a short awn; III and following bearded at the base; lateral lobes 

 simple, lanceolate, and awned or irregularly toothed in the inner margins, or rarely 

 with a small tooth at its inner base ; awn usually twice or thrice as long as the glume, 

 erect and flexuous, or recurved; palea elliptic-oblong, obtuse, keels scabrid. — In the 

 Sikkim specimens gl. I and II are sometimes very long lanceolate arista tely acumi- 

 nate with the lobe of I placed lower down, in others gl. I is much shorter than II, 

 with a broad lateral lobe towards its base ; in others again gl. I is deeply notched 

 on one side towards the tip only; gl. II is 2-toothed below the tip and has 5 con- 

 tiguous strands on the thickened disk ; gl. Ill and its palea are longer and narrower 

 than in any Khasia form, where, however, the plant is so variable that I hesitate to 

 regard the Sikkim one as a different species.

Mtsoee ; at Bellary (1834) Wight (n. 1798 ?). 



Spikes 6-8 in., rachis as stout as a sparrow's quill. Spikelets 10-12, from ^1^ in. 

 apart; gl. I and II linear-oblong, membranous, hyaline, with a strong defined 

 midrib ; III rather narrow, base bearded, lateral lobes lanceolate not awned ; palea 

 oblong, keels obscurely scabrid. — A very distinct species, of which there are only 

 spikes in Wight's Herbarium. Bellary is a botauically unexplored district.

Rajputana ; Mt. Abu, DutMe. The Conoan, Canaea, and Mysoeb, Jacque- 

 mont, &c. 



Stem stout or slender, in Jacqnemont's specimen 3 ft. high and as thick as a 

 duck's quill below. Leaves 1-2 ft. by ^— Jin. , quite smooth, flat or convolute. 

 Spikes 6-10 in.; rachis stout or slender, strict. Spikelets usually densely crowded; 

 glumes coriaceous; lobes of III short membranous not awned, base very shortly 

 bearded ; awn \ the length of its gl. or shorter ; palea oblong, keels scabernlous. — 

 The difference in stoutness of stem and spike, and of size of the spikelets is remark- 

 able.
