Abstract

Studies on the flora of Turkey are still important. In the present research, we aimed to determine the flora of Taşlıyayla and Kızık surroundings. Research field is located between Bolu and Seben in Bolu province. It covers the Alms Solaklar, Nimetli, Dedeler, Ayman, Korucuk, Hacıoğlan, Bozyer, Alpagut, Kozyaka, Keskinli and Demirciler together with the villages of Kızık, Dereceören, Kuzgölcük and Kabak. According to the P.H.Davis's grid system, it is in the A3 square. As a result of 35 times excursions to research area, 1750 plant samples were collected in different vegetation periods from February 2010 to October 2011. As a consequence of identification of the plant specimens collected, 575 taxa belonging to 298 genera and 80 families have been determined. 80 of these taxa are endemic for Turkey. The largest families recorded are as follows: Fabaceae-61 taxa (% 10.64), Asteraceae-56 taxa (% 9.77), Labiatae-42 taxa (% 7.32), Poaceae-32 taxa (% 5.58), Brassicaceae-31 taxa (% 5,41). The phytogeographical distribution of determined taxa are as fallows; Euro-Siberian 129 (% 22.5), Irano-Turanian 57 (%9.94), Mediterranean: 52 (9.07). In the study, 58 taxa have been determined as new records for the A3 square.
