The water-nut or Singhara of India is not much cultivated in Burma, but it is 

 capable of yielding a prodigious supply of food, as, for example, in Kashmir, where it 

 forms the staple food of some 30,000 souls for four or five months of the year. The 

 nuts can be eaten raw, but are more palatable boiled, and have been likened to 

 chestnuts in flavour.
