Identities of two currently recognized hybrids were tested using molecular analyses of plants from the original clones growing at the type localities. DNA sequencing revealed their correct identity, which differ from the current view based on morphological comparison. One of the hybrids, P. gramineus × P. polygonifolius, is a relic surviving in Sweden although one of its parents, P. nodosus, currently does not occur in the whole of Scandinavia.
