There are several plants with the name lotus.
The aquatic plant:
The best known lotus is a plant of the genus Nymphaea (the Egyptian lotus, family Nymphaeaceae) or Nelumbo (the Indian lotus). Both plants have round leaves that float on the surface of water; Nymphaea leaves have a radial notch, which Nelumbo leaves do not. Nelumbo fruit is often used in flower arrangements; it has about twenty pits in its face, each of which contains a seed. Members of Nymphaeaceae are called waterlilies. Both plants have been used as religious symbols.

The lotus tree
The word "lotus" is also applied to unrelated and unresembling plants. The Lotus-eaters of the Odyssey are thought to have eaten a species of jujube or Zizyphus; this would be the lotus tree that the mythological Lotis had been transformed into. The genus Lotus belongs to the Fabaceae.
