Vegetative characteristics

The rhizomes are short, vertical, and tuberous. [2] The pubescent leaves [5] have a dentate [2] [5] crenate, or serrate margin. [5]

Generative characteristics

The blue, [6] white, cream, yellow, magenta, or pink, [5] nocturnal or diurnal, emergent flowers [2] extend up to 20 cm above the water surface. [5] The stamens do not have sterile appendages at the apex. [2]

Cytology

In Nymphaea pubescens and Nymphaea lotus, the chromosome count is 2n = 56. They are tetraploid species. [7]

Taxonomy

Publication

It was published as Nymphaea sect. Lotos DC. by Augustin Pyramus de Candolle in 1821. Later, it was elevated to the subgenus Nymphaea subgen. Lotos (DC.) Conard published by Henry Shoemaker Conard in 1905. [3] [1]

Type species

The type species is Nymphaea lotus L. [2]

Species

Fossil record

Fossils from the upper Oligocene (28.4–23.0 million years ago) of France have been assigned to Nymphaea subg. Lotos. [8] It is also known from the Rupelian (33.9 – 27.82 Ma) of Bad Häring, Austria. [10]

Distribution

It is native to the paleotropis. [2]

Ecology

Pollination

Beetle pollination by Ruteloryctes morio has been reported in Nymphaea subg. Lotos. [16] [17] [18]
