Zizania aquatica and Z. palustris are important constituents of aquatic plant communities in North America, providing food and shelter for numerous animal species. Zizania palustris is also an important food source for humans. Zizania texana is federally listed as an endangered species in the United States. Zizania latifolia, an Asian species, is available through horticultural outlets despite its potential for harboring a fungus that would devastate the native species (for additional information, see the comment following the species description).</p> |tables= |references={{Treatment/Reference |id=aiken1988a |text=Aiken, S.G., P.F.
