Analysis of the family Poaceae (Gramineae) on the subalpine grassland flora of ΝΕ. Greece

The present paper is dealing with the chloristic, phytogeographical analysis of the family Poaceae (Gramineae) of the subalpine and the upper montane grasslands of North East Greece. Α list of 62 taxa, which are classified to 25 genera, 56 species and 6 subspecies, is presented. The majority of the taxa are caespitose hemicryptophytes (>90%). On the basis of duration of life, perennial herbs predominate. Conceming their chorology, there is an obvious dominance of the wide spread-in a wide sense taxa-with an abundance of Balkan endemics. The geographical distribution of the species of the family in various mountains of ΝΕ . Greece is also presented.
