Nuphar variegata is distinct throughout most of its range. The leaves are characteristically floating, being emergent only under low-water conditions. Intermediates between N . variegata and N . microphylla , probably of hybrid origin, are treated as N . rubrodisca . Some intergrading of characteristics occurs where the range overlaps with N . advena (E. O. Beal 1956). This can be observed in the mid-Atlantic region. Intermediates between N . variegata and N . polysepala occur in eastern British Columbia where the two species are sympatric. Authorship and typification of this name were discussed by E. G. Voss (1965).

fourni par wikipedia EN
Nuphar variegata (variegated pond-lily, bullhead pond-lily or yellow pond-lily[1]) is a plant in the water lily family, Nymphaeaceae. It is native to much of Canada and the northernmost of the United States.[2][3]
Description
Nuphar variegata is an aquatic plant with alternate, simple leaves, on submerged stems. The leaves tend to float on the surface of the water, rather than emerge above as in other Canadian species of Nuphar. The flowers are yellow, borne in summer.
