Stem ascending, 6-8 ft. high'; nodes softly bearded, rarely glabrescent. Leaves 

 6-10 by -| in., and sheaths giabrous or hairy ; ligule short, ciliate. Panicle 

 erect, 3-5 in. ; rachis stiff, scabrid. Spikes rather distant, stout, simple or divided 

 below; lower 2-4 in., upper gradually shorter, rachis -^in. broad subhispid. Spike-, 

 lets turgid, sometimes solitary and alternate throughout the spike, green or 

 purplish ; gl. IV obscurely dotted or roughened. The Water-grass of the Mauritius 

 and 'Ce>lon. I find gl. Ill to be always male, but being described as neuter by 

 others it no doubb varies in this respect, as do so many other Panica,. It is very 

 ik-ar the American P. molle, Sw., and is often confounded with it, and the English 

 names given above apply to both. It is distinguished from P. molee by the glabrous 

 panicle and 1-nerved (not 3-uerved) gl. I.
