Résumé
The study area located in the South-east part of Central Anatolia is under the influences of mediterranean climate with semi-aride lower very cold type. 305 taxa (including infraspesific rank) were determined in the study area and assessed in the Irano-Turanian floristic region from the phytogeographic point of view. The vegetation of the area was analysed by Braun-Blanquet method and classified into 4 associations, two subassociatons and a plant group. Two associations and subassociations are new for science. All syntaxa described here were attached to the alliance Phlomido armeniacae - Astragalion microcephali (Akman, Ketenoğlu, Quezel, Demirörs, 1984.) Associations and their higher units are as follows : Super-Class : Daphno - Festucetales Quezel, 1972. Class : Astragalo-Brometea Quezel, 1973 Order : Onobrychido armenae - Thymetalia leucostomi Akman, Ketenoğlu, Quezel, 1985 Alliance : Phlomido armeniacae -Astragalion microcephali Akman, Ketenoğlu, Quezel, Demirörs, 1984. Association : Stachyo ibericae-Artemisetum scopariae Assjmva Association : Achilleo coarctatae-Polygonetum arenastri Ass.nova Association : Sdlvio cryptantae-Astragaletum lycii Association : Astragaletum microcephali Sub- Association : tkymetosum spylei subass.nova Sub-Association : phlomictetosum armeniacae subass.nova Plant comminity : Centawea spinosa 2003, 101 pages Key Words : Syntaxonomy, Steppe vegetation, Central Anatolia.
