Description	Potamogeton x salicifolius, a hybrid between P. lucens and P. perfoliatus, was identified as a new taxon for Italy. This is the first record of this hybrid from southern Europe. The Italian sample was studied in cultivation and compared with a living specimen of P. x salicifolius from Sweden, where the hybrid is rather widespread. In addition to morphological features, the most compelling evidence for the hybrid origin of these plants came from the isozyme analysis. The additive %22hybrid%22 banding patterns of the five enzyme systems studied indicate inheritance from P. lucens and P. perfoliatus. The distribution of this hybrid in Europe coincides with the areas most severely affected by the Late Pleistocene glaciation. The relationships between environmental conditions, history of the habitat and rise of hybrids are discussed.

(en) Na základě podrobného morfologického rozboru a analýzy isozymů byl jako nový taxon pro jižní Evropu identifikován hybrid Potamogeton x salicifolius. Studium isozymových fenotypů prokázalo, že jihoevropské i skandinávské rostliny tohoto taxonu vznikly křížením druhů P. lucens a P. perfoliatus. Podrobnosti vzniku a historie klonů těchto kříženců jsou diskutovány ve vztahu ke vhodným ekologickým podmínkám v jezerech, které vznikly v územích nejvíce zasažených posledním zaledněním. (cs)
