Misc. Various species (N. advena, N. variegatum, N. microphyllum) have been "lumped" into N. lutea. Taxonomy of Nuphar in North America is not very clear; in fact, genetic studies indicate that they may not be related to the Eurasian Nuphar and may in fact warrant additional names.
"lutea", yellow. 
Insect pollinated.
The roots and seeds are edible and were used by some Native American tribes by roasting and grinding into flour, and for thickening soups.
