286 CLXXIII. GRAMINEJI. (J. D. Hooker.) [Tripogan. 



much longer than the spike, acute ; sheaths striate, lower lax j ligule ovate, obtuse. 

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



3. T. trifidus, Munro, ex Stapf in Kew Bulletin (1892) p. 85 ; spikelets 

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

 notched below the tip, III villous at the base, awn twice as long as the gl. 

 or longer. 



SIKKIM HIMALAYA, alt. 5-6000 ft., J.D.H. MISHMI HILLS, Griffith. KHASIA 

 HILLS, alt. 4^5500 ft., Griffith. (Kew Distrib. n. 6633, 6634). DISTRIB. Tonkin. 



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 aristately acumi- 

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

 with a broad lateral lobe ton ards 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. 



4. T. Wig-htii, Hook. f. ; spikelets 1-1 in. 10-30-fld., gl. I and II 

 subequal linear-oblong tip 2-toothed and mucronate, awn recurved as long 

 or twice as long as its gl. 



MYSORE ; at Bellary (1834) Wight (n. 1793 ?). 



Spikes 6-8 in., rachis as stout as a sparrow's quill. Spikelets 1012, 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 botanically unexplored district. 



ft Awn shorter than its gl. 



5. T. Xiisboae, Stapf in Kew Bulletin (1892) 86; spikelets ^-\ in. 

 5-12-fld., gl. I lanceolate obtusely toothed on one side, II twice as long 

 linear-oblong coriaceous apiculate, awn of III very short. Leptochloa

RAJPUTANA ; Mt. Abu, Duthie. The CONCAN, CANAEA, and MYSORE, Jacque~ 

 mont, &c. 



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

 duck's quill below. Leaves 1-2 ft. by --i in., 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 scaberulous. 

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

 able.
