This study is concerned with the flora of Kayışdağı and Yeditepe University 26 Ağustos Campus, which are located in district of Ataşehir, İstanbul. According to our field studies and literature screening, a total number of 476 taxa which consist of 262 genera from 73 families grow in the area. The highest number of taxa belongs to the familiy Asteraceae 65; 13.7% . It is followed by the families Fabaceae 63; 13.2% and Poaceae 46; 9.7% . Besides, Trifolium L. 19; 4.0% is the genus with the highest number of taxa which is followed by Ranunculus L. 11; 2.3% , Vicia L. 8; 1.7% and Lathyrus L. 8; 1.7% . The phytogeographical regions of 175 36.76% taxa in the research field could be identified. The distribution of these taxa in the phytogeographical regions are as follows; Mediterranean element 105; 22.06% , Euro-Siberian element 67; 14.07% , Irano-Turanian element 3; 0.63% . 11 numbers %2.31 of endemic and 3 numbers of rare taxa were identified in the research field. Moreover, the threat categories of these plants according to IUCN were added to the floristic list. The results of our research are compared with the studied neighboring areas in means of phytogeographic element rates and endemism. Also taxa similarity is compared by Jaccard similarity index
Bu çalışma, İstanbul ili Ataşehir ilçe sınırlarında bulunan Kayış dağı ve Yeditepe Üniversitesi 26 Ağustos Yerleşim Alanı’nın florası ile ilgilidir. Yapılan arazi çalışmaları ve literatür taramaları sonucunda alanda, 73 familyadan 262 cins ve bu cinslere ait toplam 476 taksonun yetiştiği belirlenmiştir. En fazla takson içeren familya Asteraceae 65; %13.7 ’dir. Bunu Fabaceae 63; %13.2 ve Poaceae 46; %9.7 izlemektedir. Ayrıca en fazla taksona sahip cins Trifolium L. 19; %4.0 olup, bunu Ranunculus L. 11; %2.3 , Vicia L. 8; %1.7 ve Lathyrus L. 8; %1.7 izlemektedir. Araştırma alanındaki 175 %36.76 taksonun fitocoğrafik bölgesi belirlenebilmiştir. Bu taksonların fitocoğrafik bölgeler içindeki dağılımı şu şekildedir: Akdeniz elementi 105; % 22.06 , Avrupa-Sibirya elementi 67; %14.07 , İran-Turan elementi 3; %0.63 . Araştırma alanında 11 adet endemik %2.31 ve 3 adet nadir takson tespit edilmiş olup bu bitkilerin IUCN’e göre tehlike kategorileri floristik listeye eklenmiştir. Çalışmanın sonuçları inceleme alanının yakın çevresinde yapılmış olan çalışmalarla fitocoğrafik bölge elementleri ve endemizm yönünden karşılaştırılmıştır. Ayrıca Jaccard benzerlik indeksi kullanılarak alanlar takson benzerlikleri yönünden karşılaştırılmıştır
