Generative characteristics
The filament is lanceolate. The yellow stigma has a hemispherical, short projection in the centre of the stigma.[2]
Cytology
It exhibits an intermediate genome size.[2]
Reproduction
Generative reproduction
Nymphaea × borealis exhibits lower fertility and pollen production.[2]
Natural hybridisation
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
Publication
It was first described by Edmond Gustave Camus in 1898.[1]
