REMARK

Aggr. P. balfouri (34) is one of the most difficult aggregates in section Stenopoa. It combines the population, resulted presumably from hybridization of P. nemoralis and P. glauca . Species and population of uncertain taxonomic rank, attributed to this aggregate, are more mesomorphic than the common samples of P. glauca , and the uppermost node among these populations is much higher ( Olonova 1998). Pleistocene migration resulted in massive hybridization between P. nemoralis and P. glauca not only in Scandinavia, but also in Central Europe.
