There are only two "Lotus-Lilies" in the family Nelumbonaceae and both are in the same genus - Nelumbo. The photo on the right is a typical form of the plants in the Nelumbonaceae (adapted from a Russian source).
There is some disagreement as to the placement of the genus Nelumbo. In the recent past it was placed in the water lily family (Nymphaceae).
