Özet
Dianthus erinaceus Boiss. var. erinaceus is an endemic living on tops of four mountains in t he Aegean region of Turkiye. The aim of this study was to investigat e the distribution area, the risk category accordin g to IUCN V 3.1, the habitat features and the relations between some of these features and reproductive success Dianthus erinaceus Boiss. var. erinaceus . The number of individual is highest on Spil Da g and lowest on Sarikaya Tepe. The widest distribution area is on Nif Da g. The soils supporting these populations are slightly alkaline with pH 7.1 and 7.5, nonsaline, rich in C aCO 3 content and poor in organic matter. Total yearly ra infall is little over 1000 mm in the study area ex cept Sarikaya Tepe and about 950 mm on Sarikaya Tepe. The temperatures are below 0 0 C from December to March at Spil Da g and Nif Da g. Plants of Nif Da g population are bigger than other populations with bigger leaves. Number of flowers is highest in Sarikaya Tepe population. Mean viable seed number in a flower is maximum in the individuals of Spil Da g while this number is minumum in Sarikaya Tepe individuals. Due to lowest mean number of viable seed in the individuals of Sarikaya Tepe, number of viable seeds in unit is also low. There is a negative relation between annual mean te mperature but positive between total annual rainfal l and number of individual. A negative corralation was o btained between the amounts of K
