The Family Nelumbonaceae is further organized into finer groupings including:
- Genus (3): Nelumbago · Nelumbium · Nelumbo
- Species: ZipcodeZoo has pages for 87 species, subspecies, varieties, forms, and cultivars in the Family Nelumbonaceae.
Nelumbo is a genus of water flowers or water lilies commonly known as lotus (Hindi: à¤•à¤®à¤²). The word originates 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 is 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. [more]
At least 63 species and subspecies belong to the Genus Nelumbo.
