Nuphar advena, Ait.; Pursh. Flor. 2, p. 369; Torr. 16 Gray, Flor. 1, p. 58. Whole plant 

 large ; pods of the size of an egg. Common in the Klamath basin. Klamath marsh is half 

 covered by the floating leaves. The seeds, which fill the large pods, are larger than those of 

 the eastern plant, and form an important article of subsistence among the Indians. We saw 

 many hundred bushels of the pods collected for winter use. The seed tastes like that of the 

 broom corn, and is apparently very nutritious.
