Glabrous marsli or aquatic grasses. Leaves linear or lanceolate. 

 Spikelets 1-2-fid., subseBsile aud subsecund oa the branches of a sinaple 

 panicle which are produced in an awn-like bristle beyond the terminal 

 spikelet, obscurely articulate on their pedicels, narrowly lanceolate. ^ Glumes 

 4, I very small, truncate, hyaline, nerveless ; II longest, acuminate ot 

 narrowed into rigid awn, 6-many-nerved; HI lanceolate acute or aristately 

 acuminate paleate male or neuter ; IV very small, oblong, tyaline, fern, or 

 bisexual; palea hyaline. Lodicules of male fl. cuneiform. Stamens o. 

 Styles free. Graiyi linear-oblong, compressed, free within thegl. — Species 

 6-6, trop. As. and Austral. - 



Besides the spikelets on the branches of the panicle, there are often one or more 

 on the peduncle below the panicle, which are appressed, and sometimes somewhat 

 sunk in a groove of the peduncle. The species are very variable.
