Throughout INDIA ; from the Panjab eastwards to Burma, and southwards to 

 Malabar and Mysore. 



Perennial ; stem 6 to 3 ft., erect or base decumbent, rarely as stout at the base 

 as a goose-quill, usually slender; nodes often bearded. Leaves 4-8 in., narrow, 

 smooth or scaberulous, floral scabrid with tubercled margins, upper glabrous or 

 hairy ; lignle membranous, truncate. Panicle long or short, more or less compound ; 

 branches crowded or distant, strict or geniculate ; nodes bearded ; lower spathes 

 foliaceous, floral 55 in., keels and margins tubercled. Involucr. spikelets male or 

 neuter, pedicelled, oblong-lanceolate ; gl. I 5-ribbed, scaberulous. Bisexual spikelets, 

 gl. I bicuepidate ; II 3-nerved ; IV a slender awn three times as long as the spikelet 

 or longer. Very variable in stature, length of leaves and habit of the panicle. 



2. X. argutum, Anderss. I. c. 252 ; panicle linear elongate very lax, 

 spathes elliptic-lanceolate about three times as long as the peduncle of the 

 spike, invol. spikelets in. shorter than the bisexual. Hack. Monogr.

BURMA ; at Prome, Wallich. 



Stem 2-3 ft., very slender, leafy at the base, compressed below. Leaves 3-6 in., 

 narrowly linear, coriaceous, smooth except towards the spinulose rounded tips, deeply 

 striate, midrib broad, floral with spinulose margins and ciliate buse; sheath coin- 

 pressed; ligule a very short membrane. Panicle almost filiform, flexuous, with 

 distant almost capillary branches ; nodes ciliate ; spathes -f in., keels and nerves 

 granulate or tubercled. Invol. spikelets shortly stoutly pedicelled, linear-lanceolate ; 

 glumes 2, I 5-ribbed scaberulous, keels ciliate, tubercled ; II 3-nerved. Bisexual 

 spikelets linear-lanceolate ; gl. I long-beaked, beak scabrid ; IV a slender awn. The 

 materials are scanty ; more specimens may modify the above characters.
