XYHl SYNOPSIS OF GENERA. 



sterile. Pedicels usually adnate to the rachis. (Vide 

 Plate C, Fig. 13). 



Hemarthria, p. 30. 

 #### Spikelets of each pair bearing two kinds of florets. 



E lowering glume of the fertile one usually awned. 

 t Spikelets in many pairs along the rachis of the simple 

 spikes or panicle branches. 

 Spikes 2 — 3, rarely solitary. The sessile spikelets have 

 a male floret below the terminal fertile one. 



Isch^mum, p. 30. 

 Spike solitary. Spikelets 1-flowered, appressed, imbri- 

 cate. Sessile florets of each pair fertile, all facing one 

 side, their flowering glumes with a long twisted awn. 

 Stalked florets male or sterile, not awned. (Spear 



Heteropogon, p. 32. 

 Spikes solitary, in pairs, or several. Sessile spikelet of 

 each pair fertile and with a long twisted awn ; the 

 stalked spikelets sterile, not awned, Pale small or 

 none. (Khas-khas, palwa, &c.) (Vide Plate C, Figs. 

 14 to 16). 



iVNDROPOGON, p. 33. 



ft Spikelets in triplets at the ends of the panicle branches, 



or in dense clusters. 



Spikelets in triplets on the jointed branchlets of the 

 panicle ; central one sessile and fertile, the two lateral 

 ones stalked and sterile with occasionally 1 — 3 addi- 

 tional pairs below. (Vide Plate D., Fig. 17). 



Chrysopogon, p. 39. 



Spikelets as in Chrgsopogon, but the panicle branches 

 are scarcely jointed, and the ovate outer glume of the 

 fertile spikelet becomes hard. (Judr). (Vide Plat eD., 



Fig. 18). 



Sorghum, p. 40. 

 Spikes or clusters arranged on a leafy panicle, and 

 composed of seven or more spikelets, four of these, i.e*, 

 two pairs, which are either empty or contain male florets, 

 surround the three terminal spikelets in the form of an 

 involucre. Terminal spikelets stalked, the central one 

 fertile, the two lateral ones usually sterile. (Vide Plate 



D., Fig. 19). 



Anthistiria, p. 42.
