REMARK Morphologically very similar to P.pratensis , this species differs from it in narrower leaves and moderately pubescent lemmas. Originated apparently from hybridization between P. pratensis and some species of sections Homalopoa or Macropoa, it replaces P. pratensis in forests. All samples of P. subglabriflora Roshev. and P. angustiglumis Roshev. from Yakutia are to be attributed to P.sergievskajae . Detailed studies have also shown that all samples of P. raduliformis Robat. reported in Yakutia ( Olonova 1990) were attributed to this species, based only on formal features, and rather belong to P. sergievskajae as well.
