Tropical HiMALATA, from Garwhal to Sikkim. Lower Bengal, Assam, tbe 

 Central Provinces, and Burma. — Distrib. Tonkin. 



Stem 2-3 ft., decumbent and branched below, leafy, nodes glabrous or nearly w. 

 Leaves 12-16 by ^-J in., glabrous or hairy, base narrowed, setaceously acuminate, 

 scaberuloaa ; sheath hirsute or subglabrous, mouth bearded ; ligule shortly orate. 

 Panicle 1-2 in., loug-peduncled, usually narrow, green or purplish ; rachis slender, 

 glabrous or nodes bearded ; branches erect, lower usually biiiate covered to the bn^ 

 with spikes. Spikes i-^ in. ; joints few. flattened but not 2-ribbed, ciliate with 

 white or purple hairs. Sessile spikelets dorsally flattened, callus bearded; gls. thm, 

 I glabrous on back and sides, margins involute, nerves very slender; II c"*^' 

 eeouB, acute, 5-7-nerved ; III Lanceolate, 2-nerved, ciliate; iV much shorter, 2-Dd, 

 lobes triangular, ciliate ; awn J in. long; palea 0, or minute, broadly ovate. Oroy 

 glabrous. Pedlcelled spikelefs neuter, narrower than the sessile ; gl. I many-nerred, 

 keels scaberulous ; II acute, 7-nerved ; III obovate-oblong, ciliate, — A good character 

 of this species is the branches of the panicle bearing spikelets down close to tw 

 rachis. Hackel (who doubtfully places this in his subgenus Sorghum) describes gi. 

 IV of the sessile spikelet as having a lanceolate acuminate glabrous nerveless pa^** 

 as long as the gl. ; no doubt an error.

 narrow, sheaths hardly compressed, panicle elongate interrnpted, racni* 

 and spreading opposite and alternate branches capillary glabrous, spisw

 nelled, sessile spikelets narrowly lanceolate acute, gl. I dorsally coo^

 of hairs. Panicle 12-16 in., dull purplish, much branched. Spikes ^^^^y'^^^

 IV linear, 2-fid, awn very slender. Pedicelled spikelets longer than the se*^^^^ ^i 

 more acuminate, nearly glabrous, male ; gl. I 7.nerved, 3 towards the margin *^"^ 

 side; II and III as in the sessile; IV narrow, glabrous, awn 0.— Hackel, whop 

 this in suhgen. Vetiveria, describes gl. I of the pedicelled spikelet as 5-nerved. ^^ 

 habit spikelets and glumes are those of subgen. Amphilophis, but the j^^^^i^jj, 

 pedicels arc not channelled. Duthie {Grass. N.W. Ind. 22) gives the JD® 

 Valley, Stewart, as a habitat, doubtless erroneously.
