In this study, the floristic composition of Porsuk Stream has been investigated. The study area is in the B3 and B4 square according to the Grid System of Davis 1965 . 800 plant specimens were collected from the area between 2001 and 2002. After the identification of the specimens revealed the presence of 266 taxa belonging to 170 genera and 59 families. 218 species, 29 subspecies and 19 varietes were identificated. A total of 26 taxa 9.77% are endemic for Turkey. The distribution rates of taxa into phytogeographical regions: Irano–Turanian elements are 12.78%, Euro–Siberian elements are 10.14% and Mediterranean elements are 7.89%. 41 taxa are new records for B3 and B4 squares. Besides, it was determined that 33 taxa take place in risk categories
Bu çalışmada doğası giderek bozulan Porsuk Çayı’nın floristik yapısı ortaya konulmuştur. Araştırma alanı, Davis’in 1965 kareleme sistemine göre B3 ve B4 karesi sınırları içerisinde yer almaktadır. 2001-2002 yılları arasında yapılan arazi çalışmalarıyla 800 bitki örneği toplanmıştır. Toplanan örneklerin teşhisi sonucu 59 familya ve 170 cinse ait 266 takson tespit edilmiştir. Bunlardan 218’i tür, 30’u alttür ve 18’i varyete seviyesindedir. Bu taksonların 26’sı endemik olup, endemizm oranı %9,77’dir. Taksonların fitocoğrafik bölgelere göre oranları ise şöyledir: %12,78’i İran–Turan elementi, %10,14’ü Avrupa–Sibirya elementi ve %7,89’u Akdeniz fitocoğrafya bölgesinin elementidir. Alanda belirtilen taksonlardan 41’i B3 ve B4 karesi için yeni kare kayıttır. Ayrıca 33 bitki taksonunun da tehlike kategorileri belirlenmiştir
