Value as a fodder. This grass is closely allied to that which pro- 

 duces rice. It is a semi-aquatic grass which is so sparingly distributed

 It is, however, a tender grass, much liked by stock, and Duthie quotes 

 Symonds as stating that cattle are fond of it in India. 



" A widely-distributed perennial swamp-grass found in warm regions 

 of both hemispheres. In the Philippine Islands it is regularly culti- 

 vated, under the name of Zacate, for the purpose of supplying food
