L. 2-l"2''' long- (F.B.I., not over tt" in our sjiecimens), •1-"17'' broad with lon^: 

 hairs near the base and often shortly liairy on one or both surfaces, scaberulons 

 after fall of the hairs. Sheaths usually scaberulons. Ligule short, membranous, 

 truncate. Spikes usually 3-9. Sessile spkt. gl, ii cymbiform acute or acuminate, 

 keeled and with marginal nerve and sometimes 1-2 faint ones between keel and 

 each margin, slightly longer than i ; iii narrow lanceolate hj-aline about four- 

 fifths i ; iv the slightly dilated base of the ■5-'75"-long capillary- awn. Fed. spkt. 

 equals the sessile, gl. i keels sometimes minutely produced, U-nerved (7-13-. 

 F.B.I.), glabrous, pitted or not, keels ciliolate ; ii flat dorsally, 3-5-nerved, obtuse ; 

 iii broadly oblong (linear-ol)long, F.B.I.) glabrous. 



The following form or varieties occur : — 



a. genuinus, Hackel. Gl. i thin, not shining, villous below the middle, spikes 

 ::i-9. Singbhum and Manbhum (nee above). 



The others have very shining gl. i often glabrous, and glabrous leaf-sheaths, but 

 it is not apparent under which of Ilackel'g varieties they come unless insculptus 

 with gl. i sometimes 2-pitted and the keels of gl. i longer ciliate which they 

 s;ometimes are. Yar. gejiuiims has sometimes shining glumes.

Stout, about 4 ft. high Avith culms -25" diam. at base, nodes mostly 

 <lensely villous. Leaves and sheaths glabrous, blade up to 2 ft. by 

 •3" or upper appressed hairy Avithin above the short hard truncate 

 ligule, blade narrow up to 2 ft. by -3" tapering from base to tip, with 

 5-7 strong nerves between margin and midrib, margins setulose. 

 Panicles 3" Avith the rhachis much shorter than the alternate, rarely 

 also opposite, simple peduncled spikes Avhich lack the axillary ciliate 

 tubercles of pertusa and glabra. .Spikelets purple, callus obtuse 

 bearded. Sessile spkt. -2" ; gl. i thinly hairy on lower half dorsally, 

 narrowly elliptic-oblong, obtuse, keels hispiclulous above ; ii cymbi- 

 form, very acute, -18" long, 3-nerved ; iii hyaline, '14", broadly oblong, 

 obtuse ; iv linear 1 -nerved forming the base of the short nearly straight 

 awn which is only -25" long. Palea ciliate one-third gl. iii. Ovary 

 small with 2 long stjdes and plumose stigmas. Ped. spkt. -18", gl. i 

 like that of sess. spkt. but 9-11 -nerved between the keels and often 

 punctate above the middle ; ii oblong obtuse with rounded back, 

 hyaline with 5 green nerves, subequal ; iii ell. -oblong hyaline ciliate

The Santal Parganah's plant is much stouter than anj- si)ecimens at Kew and 

 is the one more especially described.

 culms more or less compressed beloAv. LoAA^er leaf-sheaths mvich 

 compressed, flabellate-imbricate, leaves firm, concluplicate in bud, 

 flattening out upAvards, gradually passing into the sheath. Spikelets 

 2-nate, sessile and pedicelled, subsimilar, differing in sex, on the 

 articulate fragile rhachis of peduncled 3-many-noded racemes Avhich 

 are in manj^-rayed Avhorls round the rhachis of nearly simple elongate
