Nuphar advena is extremely variable and intergrades with N . orbiculata , N . ulvacea , and N . sagittifolia in areas of sympatry. Intergradation with N . variegata (E. O. Beal 1956) can be observed in the mid-Atlantic region, although most floristic treatments from the area of overlap treat the two taxa as distinct species. Local variation in the Ozark Mountains and in Texas, the basis for the names Nymphaea ozarkana , N . ovata , and N . puberula , is not considered sufficient to warrant recognition.

Nuphar advena
provided by wikipedia EN
Nuphar advena (spatterdock or cow lily or yellow pond-lily) is a species of Nuphar native throughout the eastern United States and in some parts of Canada, such as Nova Scotia.[1][2] It is similar to the Eurasian species N. lutea, and is treated as a subspecies of it by some botanists,[3] though differing significantly in genetics.[1]
It is locally naturalized in Britain.[4]
Uses
Spatterdock was long used in traditional medicine, with the root applied to the skin and/or both the root and seeds eaten for a variety of conditions. The seeds are edible, and can be ground into flour. The root is edible too, but can prove to be incredibly bitter in some plants.[5]
