sheaths lax, upper smooth pale spathiform ; ligule 0. Spikes -! i n -> flexuous, 

 nodding or cernuous silvery-green, lowest pairs of spikelets male ; peduncles i- in., 

 capillary, axils with whorls of long white hairs ; rachis and pedioels slender, terete, 

 silkily ciliate, upper hairs long. Sessile spikelets in. ; callus very short, silkily 

 bearded ; gl. I thin, pale, nerveless, with often a large deep dorsal pit, margins 

 narrowly incurved ; II acute, nerveless, dorsally silkily villous; III oblong or linear, 

 flat, hyaline, obtuse, nerveless; IV, awn about 1 in., slender, nearly smooth, base 

 acute. Pedicelled spikelets -i in. rather narrower than the sessile ; gl. I slightly 

 convex, quite smooth between the bristles, keels ciliate, many-nerved ; II ovate- 

 oblong, 3-nerved, ciliate; III oblong, obtuse, eciliate; IV very narrow. 



60. A. mucronatus, Anderss. ex Hack. Monogr. Androp. 577 ; stem 

 tall stout, internodes alternately flattened, sheaths terete, leaves linear- 

 lanceolate acuminate pubescent, spikes 5-10 flabellately panicled, sessile 

 spikelets in. twice as long as the joints and ciliate pedicels, callus hairs 

 half as long as the glumes, gl. I coriaceous obovate-lanceolate obtuse 

 glabrous shining 6-nerved pitted in the middle, keels setose above the 

 middle, II as long lanceolate acute glabrous except the ciliate margin 

 3-nerved, IV a stout awn, gl. IV of pedicelled spikelets awned or mucro- 

 nate. 



INDIA? Hugel. 



Stem 3-4 ft. or taller, simple, nodes 4, bearded. Leaves flat, base fimbriate ; 

 sheaths smooth ; ligule rounded, ciliolate. Spikes solitary or opposite, shortly 

 peduncled, lower pair of spikelets male. Spikelets yellow-green ; gl. I not hyaline ab 

 the tip ; II obscurely keeled, dorsally shining ; III linear-lanceolate, nerveless, 

 ciliats ; IV awn f- in. long, stout; palea minute. Pedicelled spikelets rather longer 

 and broader than the sessile ; gl. I obliquely elliptic -oblong, violet-colrd., keels 

 setosely ciliate nearly to the base, 13-nerved ; II narrower, lanceolate, acute, 5- 

 nerved, ciliate ; III obovate-oblong, 1-nerved, ciliate; IV as long, linear, 1-nerved, 

 glabrous. Description from Hackel, who says it is a peculiar species, not allied to 

 the preceding, but rather to A . polyptychus. 



** Gl. IV of sessile spikelet %-fid, awned in the cleft. 



61. A. polyptychus, Steud. Syn. Gram. 380; stem slender erect 

 simple or branched below only, leaves erect strict softly hairy acuminate, 

 sheaths subcompressed, spikes 4-6 digitate simple or forked, joints and 

 ciliate pedicels half as long as the sessile spikelets, gl. I of sessile spikelets 

 narrowly elliptic-oblong obtuse 4-7-nerved nearly flat glabrous, margins 

 narrowly incurved, keels strongly ciliate above, II as long mucronate 

 3-nerved ciliate, IV very narrow with 2 setaceous or lanceolate lobes.

 8-16 in. by -^-i in., rigid, erect ; ligule short, rigid. Spikes usually 3, very fragile, 

 2 in. long, shortly peduncled, joints and pedicels not furrowed ; axils hairy; spikelets 

 closely imbricate, lowest pair male or neuter. Sessile spikelets -i in., callus very 

 short, shortly bearded ; gl. I not winged, sometimes depressed on the median line ; 

 II 3-nerved, glabrous except the margins, acute or aristulate ; III oblong-lanceolate, 

 acute, 1-nerved ; IV rather shorter, nearly glabrous, awn -f in. very slender; palea 

 minute, broadly ovate, ciliate. Pedicelled spikelets broader than the sessile ; gl. I 

 convex, many-nerved, narrowly winged on one side, tip membranous, keels ciliate ;
