Description
Vegetative characteristics
Nuphar × rubrodisca has 1–2.5 cm wide rhizomes. The petiolate leaves float on the water surface, or are more rarely submersed. The submerged leaves are orbicular.
Generative characteristics
The red stigmatic disk has 8-15 stigmatic rays.
Reproduction
Vegetative reproduction
It can reproduce vegetatively through rhizome fragments.
Generative reproduction
It can be sterile or fertile. The fertility rates are much lower than those of the parental species.
Taxonomy
Publication
It was first described by Thomas Morong in 1886.
Natural hybridisation
Hybridisation events of both parental species are believed to have occurred many times independently from each other.
Conservation
The NatureServe conservation status is T4 Apparently Secure.
Ecology
Habitat
It occurs in streams, tidal waters, ponds, and lakes at elevations of 0–400 m above sea level. It occurs almost exclusively within the overlapping ranges of the parental species.
