Abstract

Potamogeton x sudermanicus Hagstr. has been interpreted morphologically as a hybrid between P. acutifolius Link and P. berchtoldii Fieber. Both parents belong to section Graminifolii where hybrids appear to be less frequent than in other sections. This reputed hybrid has been recorded at only a few sites in Europe and at a single locality in Britain. Using seven different isozyme systems it was shown that all the bands present within the British population of the hybrid were found in P. acutifolius or P. berchtoldii, supporting the putative origin of this taxon. In addition, the identification of two multi-enzyme phenotypes implies that this hybrid has arisen at least twice at this site.
