The study has been carried out in order to determine the interior and exterior morphological particularities of the species Cenaurea derderiifolia and Centaurea saligna which are endemic in Flora of Turkey. In the literature, it has been indicated that C. derderiifolia is spread in the regions of Sivas, Tunceli, Elazığ and Maraş and C. saligna in the regions Maraş, Elazığ, Erzurum, Muş, Van and Hakkari. We have established two additional regions to the areas which these plants spread on. The peculiarities of the species which were collected between the years of 1981-1985 are given by measurements on the fresh and dried material and according to floristic-systematic publications in the exterior morphological part of the study.
