Description	The identity of plants morphologically intermediate between Potamogeton crispus and P. perfoliatus from two recently discovered sites, one in Moravia, Czech Republic and another in Wales, United Kingdom, was investigated with molecular markers. Evidence from restriction fragment length polymorphism analysis of the nuclear internal transcribed spacer region of ribosomal DNA and of the trnK-trnQ chloroplast DNA intergenic spacer confirmed the morphology-based determination of two putative hybrid samples as P. cooperi. The hybrids showed the ITS variants of both parental taxa, consistent with the expected biparental inheritance of nuclear DNA. The chloroplast DNA markers indicate P. crispus as the female parent in both hybridization events. The hybrid origin of another dubious sample was excluded by the molecular data, in accordance with previous morphological examination. This plant represented an extreme, narrow-leaved form of P. perfoliatus, imitating P. cooperi by some characters.
