Description
[edit]Vegetative characteristics
[edit]Nuphar × rubrodisca has 1–2.5 cm wide rhizomes. The petiolate leaves float on the water surface, or are more rarely submersed.[2]
Generative characteristics
[edit]The red stigmatic disk has 8-15 stigmatic rays.[3]
Reproduction
[edit]Vegetative reproduction
[edit]It can reproduce vegetatively through rhizome fragments.[4]
Generative reproduction
[edit]It can be sterile or fertile.[2] The fertility rates are much lower than those of the parental species.[4]
Taxonomy
[edit]Publication
[edit]It was first described by Thomas Morong in 1886.[1]
Natural hybridisation
[edit]Hybridisation events of both parental species are believed to have occurred many times independently from each other.[4]
Ecology
[edit]Habitat
[edit]It occurs in streams, tidal waters, ponds, and lakes at elevations of 0–400 m above sea level.[2] It occurs almost exclusively within the overlapping ranges of the parental species.[4]
