Description
editVegetative characteristics
editNuphar × rubrodisca has 1–2.5 cm wide rhizomes. The petiolate leaves float on the water surface, or are more rarely submersed.[2]
Generative characteristics
editThe red stigmatic disk has 8-15 stigmatic rays.[3]
Reproduction
editVegetative reproduction
editIt can reproduce vegetatively through rhizome fragments.[4]
Generative reproduction
editIt can be sterile or fertile.[2] The fertility rates are much lower than those of the parental species.[4]
Taxonomy
editPublication
editIt was first described by Thomas Morong in 1886.[1]
Natural hybridisation
editHybridisation events of both parental species are believed to have occurred many times independently from each other.[4]
Ecology
editHabitat
editIt 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]
