Lotus — Nelumbo is a genus of aquatic plants with large, showy, water lily-like flowers commonly known as lotus. The generic name is derived from the Sinhalese word Nelum. There are two species in the genus, one of which is the well-known National Flower of India. Taxonomists disagree as to exactly which family that the genus should be placed in, with many saying that it is part of the Nymphaeaceae (water lily) family, and others saying that it is part of its own unique family, the Nelumbonaceae. However, even among those plant taxonomy systems which recognize the new family, there is disagreement as to which Order that it is in: Proteales, Nymphaeales, or a unique Nelumbonales order.
Nymphaeaceae is the botanical name of a family of flowering plants. The family is also called the water lily family. The white water lily is the national flower of Bangladesh. It is also the birth flower for July.
Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on the water surface. The leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria.
Horticulturally, water lilies are divided into two main categories: hardy and tropical. Hardy water lilies bloom only during the day, but tropical water lilies can bloom either day or night, and are the only group to contain blue-flowered plants.
