Nymphaea lotus Linn. Egyptian Water Lily. Lotus.
Tropical Africa and eastern Asia. The rootstocks contain a sort of starch and are eaten by the poorer classes in India. The small seeds, called bheta, are fried in heated sand and make a light, easily digestible food. The roots are also eaten in Ceylon and the seeds are chewed by children. The tubers are much sought after by the natives as an article of food or as a medicine. The capsules and seeds are either pickled or put into curries or ground and mixed with flour to make cakes.
