of Egypt was by the ancients. The species of Eriophorum, called Cotton-grass in 

 England, from ha^'ing their fruit clothed at the base with a silky or cotton-like sub- 

 stance, of which pa[)er and wicks of candles have been made, and pillows stuffed, has 

 a species (E, comosum. Wall., cannabinum, nob.), Bhabhui* of the natives, of which the 

 leaves, previous to the plant flowering, are in the Himalayas extensively employed for 

 rope-making. Cyperus inundatus probably, with other species, helps much to bind 

 and protect the banks of the Ganges from the rapidity of the stream and the force of 

 the tides ; as in Holland Cai'ex arenaria is carefully planted on the dikes, where its far- 

 extencling roots, by mutually interlacing with each other, fix the sand and give strength 

 to the embankment." {Royle, Illustr. p. 415.) Cyperus Hydra, called Nut-grass in the 

 West Indies, is said to be a pest there, overrunning the Sugar-cane plantations, and 

 rendering them barren.
