Value as a fodder. Readily eaten by stock and believed to be a 

 very nutritious grass. " Buffaloes are said to be very fond of this 

 grass/' in India. (Duthie.) 



Habitat and range. Found in all the colonies except Tasmania, 

 usually in damp, often brackish situations. It is an interior species. 

 It also occurs in Africa and India, and " in the plains of Northern India 

 where water is liable to lodge. I have observed it in great abundance 

 in the more depressed portions of the saline usar tracts in the Aligarh 

 district." (Duthie.)
