Spikelets at apex of capillaiy branches of panicle ternate, each 2- 

 flowered, the lower floweret neuter, reduced to a membranous pale; 

 the middle spikelet sessile, perfect, the lateral pcdicelled, stamiuate. 

 Staminate spikelets: glumes 2, nearly e(|ual, longer than pale, the 

 lower coriaceous, short-bid entate, short-aristate, the upper membran-
