Özet

In this study, the genus Psathyrostachys Nevski is revised in Turkey. Furthermore multivariate analysis have been carried out in order to understand the delimitation of the taxa of Psathyrostachys. For this reason, 20 quantitative, qualitative and multi-state morphological characters were scored for the accessions representing 10 populations of the genus. The data were subjected to numerical taxonomic analysis. The results showed that the genus is represented by 3 species one of which is new species and the other one is a new record for Turkey. An account of 3 species and 4 subspecies recognized in the genus is given including the genus description, a key for the species as well as the subspecies, species descriptions, flowering times, habitats, altitudes, type citations, distributions, phytogeography and their conservation status. However, three new taxa, namely P. narmanica sp. nov., P. fragilis subsp. artvinense subsp. nov. and P. daghestanica subsp erzurumica subsp. nov. are described and illustrated for the first time.
