Elodea bifoliata
Also called Two Leaf Waterweed, Long Sheathed Waterweed, Two Leaved Waterweed
Elodea bifoliata, commonly called twoleaf waterweed, is a species of perennial flowering plant in the waterweed genus, Elodea. It grows in much of the western United States and Canada. It was only recognized as a separate species in the 1960s. It is found growing in streams and shallow bodies of water.
Elodea bifoliata has a native range that extends over much of the western United States and Canada. It is found in all the Rocky Mountain States including Montana, Idaho, Wyoming, Colorado, and New Mexico. To the east its range extends into five northern Great Plains states, Kansas, Nebraska, both Dakotas, and Minnesota. In the southwest the range includes Arizona, Utah, and Nevada. Though the USDA does not record it there, the Jepson Herbarium reports that it grows in the farthest north eastern corner of California. It also has been found in Oregon, but not in Washington State. The USDA also reports it from the eastern state of New York.
