 nodes glabrous or hirsute ; internodes 6-12 in., walls thin ; stem-sheaths papery, 

 often 12 by 3 in., glabrous and scaberulous above, hairy beneath above the middle, 

 margins ciliate, tapering to a truncate tip ; blade ^-2 in. by J^ in., subulate recurved ; 

 ligule often | in., toothed. Leaves about 3-4 by - in., or 12 by 1 in. on young

 scabrous ; palea = fl. gl. or rather longer (margins of gl. and palea often black). 

 There are two vars. : a. typica, Gamble, spikelets distant in filiform falcate racemes; 

 #. glomerata, Gamble, spikelets 3-4 together in close racemes or panicles. A. utilis, 

 Clegh., may \jefalcata or spathiflora.

 at the nodes, bracts short ovate, fl. gl. mucronate, margins above and tip 

 ciliate. Gamble Bamb. Brit. Ind. 15, t. 13. 



KHASIA HILLS ; alt. 5-6000 ft., common. 



Most difficult to separate from, A. falcata, but a stiffer stronger plant, panicle 

 more dense and imbricated, flowers shorter, rachilla of spike let hairy. 



14. A. intermedia, Munro in Trans. Linn. Soc. xvi. (1868) 28 ; stems 

 8-12 ft. slender, nodes swollen with a prominent ring and whitish line 

 below them, leaves very variable 8 by 1 in. (in young shoots to 3-4 by % in.) 

 linear- or oblong-lanceolate setaceously acuminate, base narrowed into a 

 swollen petiole, nerves 3-7 pairs with 6-7 intermediates, sparingly tessellate 

 with interposed pellucid glands, sheath ciliate with falcate auricles, 

 infl. of whorled racemose panicles, bracts axillary triangular, spikelets 

 3-5-fld., fl. gls. 7-9- nerved. Gamble Bamb. Brit. Ind. 15, t. 14. 



SIKKIM HIMALAYA, alt. 4-7000 ft., J. D. H., &c. 



Stems greyish-green; internodes 5-10 in, walls ^-4- in. thick; stem-sheaths 

 8-10 by 1-2 iu. at base, glabrous, striate, narrowed upwards and truncate, ciliate 

 below the small subulate blade. Leaves bright green, upper surface and margins 

 scabrid, midrib prominent; sheath with long marginal hairs, a minute ciliate callus 

 below the petiole and on each side a falcate auricle bordered by stiff curved bristles ; 

 ligule long. Infl. on leafless stems. Spikelets ^ 1 in., yellow or purplish, nodes of 

 rachilla clavate long-ciliate; gl. I and II ovate, membranous. The long ciliate 

 leaf-sheath is aa excellent character.
