The family Hydatellaceae was placed among the monocots in previous systems, but a 2007 study found that the family belongs to the Nymphaeales. [18] In the APG IV system, Hydatellaceae, Cabombaceae and Nymphaeaceae are the three families included in the Nymphaeales. [19]
Nymphaeaceae is a small family of three to six genera: Barclaya, Euryale, Nuphar, Nymphaea, Ondinea, and Victoria. The genus Barclaya is sometimes given rank as its own family, Barclayaceae , on the basis of an extended perianth tube (combined sepals and petals ) arising from the top of the ovary and by stamens that are joined in the base.
Nymphaeaceae (water lilies) have reticulate veins, a single cotyledon, adventitious roots, and a monocot-like vascular bundle. These examples reflect their shared ancestry. [ 36 ] Nevertheless, this list of traits is generally valid, especially when contrasting monocots with eudicots , rather than non-monocot flowering plants in general.
Nymphaea alba, from the Nymphaeales. The basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of Amborella (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody ...
Nymphaea nouchali, often known by its synonym Nymphaea stellata, or by common names blue lotus, [3] star lotus, red water lily, dwarf aquarium lily, blue water lily, blue star water lily or manel flower, is a water lily of genus Nymphaea.
In a study designed to clarify relationships between well-studied model plants such as Arabidopsis thaliana, and the basal angiosperms Amborella, Nuphar (Nymphaeaceae), Illicium, the monocots, and more derived angiosperms (eudicots), chloroplast genomes using cDNA and expressed sequence tags for floral genes, the cladogram shown below was ...
The APG system of 1998 included this family in the water lily family Nymphaeaceae, as did the APG II system, of 2003 (optionally). The APG III and APG IV systems of classification separated the family Cabombaceae from the family Nymphaeaceae. [10] [11] [12] The family is part of the order Nymphaeales, which is one of the most basal flowering ...
The lotus is often confused with the true water lilies of the genus Nymphaea, in particular N. caerulea, the "blue lotus."In fact, several older systems, such as the Bentham & Hooker system (which is widely used in the Indian subcontinent), refer to the lotus by its old synonym, Nymphaea nelumbo.
