short, ciliate. FamcU 1-2 ft., soft, quite glabrons. Bpikelets ^ia., y^\e yellow, 

 rather shining, very obscurely jointed on the pedicels which are jointed on the 

 branches.— Mi/riocfcaeto glauca, Mor., was founded on the erroneous supposition 

 that its gl. IV was hairless. The spikelets are sometimes viviparous. 



7. CKASEAERAFKIS, Br. 



Glabrous marsh or aquatic grasses. Leaves linear or lanceolate. 

 Spikelets 1-2-fld., subsessile and subsecund on the branches of a simple 

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

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

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

 narrowed into rigid awn, 5-many-nerved ; III lanceolate acute or aristately 

 acuminate paleafce male or neuter ; IV very small, oblong, hyaline, fem. or 

 bisexual; palea hyaline. Lodicules of male fl. cuneiform. Stamens 3. 

 Styles free. Grain linear-oblong, compressed, free within the gl. — Species 

 6-6, trop. As. and Austral. 



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

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

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