joints and pedicels about half as long as the sessile spikelet long-ciliate, 

 sessile spikelet in. oblong, callus short obtuse, gl. I obtuse chartaceous

HILLS ; Wight, Hohenacker, &c. 

 Steins 3-6 in., tufted, slender, sometimes creeping below, geniculafce. Leaves 

 2-3 in.,, quite flat, margins cartilaginous ; sheaths compressed ; ligule very short, 

 membranous. Spikes usually very shortly exserted from the long narrow glabrous 

 spatkes ; peduncle curved, puberulous. Spikes -f in. long, with 3-6 pairs of 

 glumes, lower spikelets neuter. Gl. I of sessile spikelets with narrowly involute 

 margins, callus bearded ; awn of IV 1^ in. long, shining. Pedicellod spikelet larger 

 than the sessile; gl. I obovate-oblong, obtuse, many and strongly nerved, margins 

 cilioi&te hardly incurved : II smallei', membranous, obtuse, 1-3-nerved, ciliate ; 

 pale* of IV very small. Hackel observes that this species is intermediate between 

 DicfatRnthium and Heteropogon, but nearer the latter in the dorsal furrow of the 

 sessile spikelet (which furrow 1 do not detect).

[PENINSULA of INDIA, Roxburgh, Wight. 



Stem 6-10 in., slender, leafy above. Leaves 2-4 by -^"TS i n -> lower flat, upper 

 convolute, acuminate, ciliate with long flexuous hairs, margins thickened ; sheaths 

 terete, lower keeled j ligule a line of hairs. Spikes pale brown (when dry), peduncle 

 2-4 in., with a very slender sheath and minute leaf about the middle ; 5 or 6 lowest 

 pairs of spikes neuter. Sessile fem. spikelets dark ; gl. I rigid, many-nerved; II linear, 

 coriaceous with broad hyaline margins; III shorter, oblong, ciliate ; IV awn rather 

 slender, column shortly hirsute. Pedicelled spikelets 3 in.; gl. I with a coriaceous 

 many-nerved centre and broad hyaline infolded wings ; II lanceolate, ciliate, 

 5-nerved, 2 pairs submarginal. Neuter spikelets ; gl. I like tbe pt dicelled, but broader, 

 tip 2-toothed ; II lanceolate, 3 -nerved, ciliate ; III and IV oblong, 1-nerved, ciliate. 

 A curious little species, of which I have seen only indifferent specimens of Wight. 

 In Roxburgh's Icones this and A. pumilus, Roxb., are figured on the same sheet with 

 the names transposed. Heteropogon polystachyon, Arn. (Wight Cat. 2321) under 

 which is cited Roxburgh's A. polystachyon is A. bellariensis, Hack. 



Subgen. XI. CYMBOPOGON, Hack. Spikes 2, both sessile or a sessile and 

 shortly stipitate terminating a peduncle which is more or less sheathed 

 by a proper spathe, often divaricate or deflexed ; joints and pedicels plano- 

 convex, clavate bucciniform or linear, top concave with usually dilated 

 toothed margins. Spikelets several pairs, lowest pair or pairs of one or 

 both spikes homogauious, male or neuter ; sessile spikelets fem. or bisexual, 

 oblong to lanceolate, dorsally compressed ; gl. I dorsally flat excavate or 

 pitted, awnless, margins inflexed; II cymbiform, acute, keeled, awned or 

 not ; III oblong, hyaline, nerveless or 2-nerved ; IV smaller, narrow, 

 hyaline, 2-cleft, awned in the cleft, awn capillary, rarely 0; palea 

 minute or 0. Pedicelled spikelets male or neuter, dorsally strongly 

 compressed.
