Nuphar × spenneriana is a species of rhizomatous aquatic plant native to Europe. It is a natural hybrid of Nuphar lutea and Nuphar pumila. [1]
Nuphar × spenneriana is a perennial, rhizomatous, aquatic plant. [2] The abaxial leaf surface has trichomes towards the leaf margin. [3] The leaf has 15-22 primary nerves. [4]
The androecium consists of 60-100 stamens. [4] The stigmatic disc has 9-15 rays. [3]
It is fertile, but the pollen may be less viable. [5] [6] Pollen fertility can reach 73%. However, it can also be as low as 14% in F1 hybrids. [6] In another case, a female sterility rate of 80%, and a male sterility rate of 85% have been reported. [7] The seeds grow more rapidly than those of the parent species. [5] [7]
It was first described by Jean François Aimé Théophile Philippe Gaudin in 1828. [1]
It likely arose 10 000 years ago, when both parent species came into contact. [8] Natural hybridisation is a threat to Nuphar pumila, one of the parent species, as the hybrid replaces populations of Nuphar pumila. [5] In Eastern Europe and Asia observations of intermediate plants are rare. In Western Europe hybridisation appears to have played a more significant role. [6]
The nothospecific epithet spenneriana honours Fridolin Carl Leopold Spenner (1798-1841). [9] [10]
It occurs in rivers, lakes, streams, and pools. [7] [2]
