Thestudyareaissuitableforplantspeciesrichnessbecauseofitsmicroclimate,soilandintensiveagriculturalactivities. Atotaltaxa of267wereidentifiedbelongingto Pteridophyta (onetaxon),Gymnospermae (fourtaxa)andAngiospermae (262taxa).Ofthese, 205taxaofAngiospermae areinMagnoliopsida and57taxaofLiliopsida.Thephytogeographicalspectrumsoftaxaareasfollows: Mediterraneanelements,61taxa(22.8%);East-Mediterraneanelements,20taxa(7.5%);Euro-Siberianelements,15taxa(5.6%); andIrano-Turanianelements,fivetaxa(1.9%).Theresultsshowthatfivetaxaareendemics.
