Stems 3-6 in., tufted, slender, sometimes creeping below, geniculate. Leatet 

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

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

 spathes; 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. Pedicelled spikelet larger 

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

 ciliolate hardly incurved : II smaller, membranous, obtuse, l-3rnerved, ciliate ; 

 palea of IV very small. — -Hacltel observes that this species is intermediate between 

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

 sessile spikelet (which furrow 1 do not detect).

Stem 6-10 in., slender, leafy above. I/eaves 2-4 by -fg-^ in., lower flat, upper 

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

 terete, lower keeled ; 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/em. 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 i in.; gl. I with a coriaceous 

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

 5-uerTed, 2 pairs submarginal. Neuter spikelets ; gl. I like the pi 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, Am. (Wight Cat. 2321) under

Subgen. XI. Cysibopogon, Haclc. Spikes 2, both sessile or a sessile and 

 shortly stipitate terminatinga 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 homogamous, male or neuter ; sessile spikelets fem. or bisexnal, 

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

 pitted, awnless, margins infleied; II oymbiiorm, 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. Fedicelled spikelets male or neuter, dorsally strongly 

 compressed.
