A new Potamogeton hybrid resulting from crossing between P. nodosus and P. perfoliatus, and occurring in Europe and Africa was described as P. × assidens. The hybrid identity was unequivocally confirmed by molecular study of ITS and selected chloroplast DNA regions. In European populations of the hybrid, maternally driven expression of characters may account to a large degree for shaping the range of morphological variability. This was accompanied by a matroclinal concerted evolution observed at the molecular level in the ITS sequences.
