A SYNOPSIS OF THE GENERA OCCURRING IN THE 

 PLAINS OF NORTH-WESTERN INDIA. 



SERIES A. Panieacese.— Pedicel jointed below the spikelet or 

 cluster of spikelets. Fertile floret solitary (except in Isachne) and 

 terminal, with sometimes~a single male or sterile one below it. 



TBIBE I. Panieese. — Spikelets hermaphrodite, in spikes or 

 panicles ; rachis of inflorescence not jointed ; flowering glume 

 not awned, becoming hard as the grain ripens. 



* Panicle spike-like, spikes simple or digitate or more or 

 less scattered along a common peduncle. Pedicels not 

 jointed. 

 Spikelets in one or two rows on one side of the flat- 

 tened rachis of each spike. Each spikelet consists of 

 one perfect flower enclosed within the two membran- 

 ous outer glumes. Flowering glume hard and thick 

 embracing the hard and thick pale. (Kodon, &c). 



Paspalum, p. 1. ^ 

 Inflorescence paniculate, branches simple and spike- 

 like. Glumes as in Paspalum, but attached to a thick- 

 ening of the pedicel above the joint. 



Eeiochloa, p. 2. 

 Panicle spreading. Spikelets 2-flowered, small. Glumes 

 4, the two lower empty ones nearly equal and usually 

 persistent below the joint, the two upper fruiting ones 

 equal and hardening. 



Isachne, p. 2. 



Inflorescence usually paniculate, simple or compound, 

 rarely reduced to a simple spike. Spikelets small, 

 1-flowered or with a male floret below it. Outer 

 glumes 2, of which one is usually much smaller or 

 even wanting. Grain enclosed in the hardened glume 

 and pale. (Sdnwak, china, Guinea grass, &c). {Vide 

 Plate A., Figs. 1 to 4).
