Nymphaea × borealis is a species of waterlily native to Sweden, Poland, Germany, the Czech Republic, and East European Russia. It is a natural hybrid of Nymphaea alba and Nymphaea candida.[1][2]

Nymphaea alba L.
Nymphaea candida C.Presl
Generative characteristics[edit]
The filament is lanceolate. The yellow stigma has a hemispherical, short projection in the centre of the stigma.[2]
Cytology[edit]
It exhibits an intermediate genome size.[2]
Reproduction[edit]
Generative reproduction[edit]
Nymphaea × borealis exhibits lower fertility and pollen production.[2]
Natural hybridisation[edit]
Nymphaea × borealis can be formed in areas of sympatric occurrence of the parent species, but the natural hybridisation of both parent species is not very frequent. Genetically confirmed hybrids are a rare occurrence.[2][3]
Taxonomy[edit]
Publication[edit]
It was first described by Edmond Gustave Camus in 1898.[1]
