മലയാളം: Nelumbo nucifera, known by a number of names including Indian lotus, sacred lotus, bean of India, or simply lotus, is a plant in the monotypic family Nelumbonaceae. The Linnaean binomial Nelumbo nucifera (Gaertn.) is the currently recognized name for this species, which has been classified under the former names, Nelumbium speciosum (Willd.) and Nymphaea nelumbo, among others. Names other than Nelumbo nucifera (Gaertn.) are obsolete synonyms and should not be used in current works. This plant is an aquatic perennial. Under favorable circumstances its seeds may remain viable for many years, with the oldest recorded lotus germination being from that of seeds 1,300 years old recovered from a dry lakebed in northeastern China.[1]

A common misconception is referring to the lotus as a water lily (Nymphaea), an entirely different plant, as can be seen in the center of the flowers, which lack the structure that goes on to form the distinctive circular seed pod in the Nelumbo nucifera.[citation needed]

Native to Tropical Asian nations and Queensland, Australia,[2][3] it is commonly cultivated in water gardens. It is also the national flower of India and Vietnam.
