Perennial or annual. Stems simple or branched, usually many-noded, 

 bearded or beardless at the nodes. Panicles usually subdigitate with a short 

 or very short primary axis, rarely the latter elongated ; racemes always shortly 

 peduncled. Spikelets small, 2-nate, one sessile, the other pedicelled, similar 

 in shape, different in sex, except the lowermost 1 or 2 pairs (sometimes 3 or 4) 

 of each raceme which are (with occasional exceptions in D. annulatum) 

 homogamous (male or neuter), in many-jointed, shortly peduncled, subdigi- 

 tate, rarely subpanicled or racemosely arranged, racemes ; joints and pedicels 

 filiform, solid, disarticulating subhorizontally except trie lowest bairen pairs ; 

 fertile sessile and pedicelled spikelets deciduous, the former with the adjacent 

 joint and pedicel. Sessile spikelet dorsally compressed, awned except the 

 basal homogamous ones , callus small, shortly bearded. Involucral glumes 

 equal, thinly chai taceous, lower usually very obtuse, 2-keeled, with narrow 

 sharply inflexed margins, upper boat-shaped, 3-nerved, acutely keeled. 

 Lower floral glume hyaline, nerveless, upper reduced to the hyaline base of a 

 slender awn ; pale minute or absent. Lodicules 2, minute, glabrous. 

 Stamens 3. Stigmas exserted laterally at or above the middle or near the tips. 

 Grain oblong, obtuse, dorsally compressed ; embryo rather more than half the 

 length of the grain. Pedicelled spikelet awnless. Lower involucral glume 

 oblong, many nerved, upper flat with sharply inflexed margins closing over the 

 hyaline lower floral glume if present and the stamens, upper floral glume 

 usually 0, never awned. 



Species 10 in the tropical and warm-temperate regions of the Old World. 



So far 4 species were known from the Presidency and described by Cooke 

 under Andropogon armatus, Hook, f., A. Cookei, Stapf, A. caricosus, Linn, 

 and A. annulatus, Forsk. To these we have added 2 new species : 

 Dichanthium panchganiense, Blatter & McCann, and D. McCannii, 

 Blatter. 



Key to the species 



A. Racemes digitate (sometimes solitary in 

 D. caricosus) , 25 mm. long or longer 

 I. Lower involucral glumes of pedicelled 

 spikelets armed with marginal bul- 

 bous-based bristles
