This research was carried out for the purpose of determining the flora of Akdag (Balikesir/Dursunbey) which located in square B2 between 2010 and 2011. A floristic survey specific to the field of research not yet done and Mediterranean, Euro-Siberian and Irano-Turanian phytogeographic region boundaries exist on the transition zone are the main factors in doing this study. 989 plant specimens were collected from the research area. As a consequence, according to evaluating of specimens 53 families and 442 taxa were identified. In this paper 72 taxa were found to be new floristic records for the B2 squares. 46 taxa collected are endemic for Turkey with %10,41 endemism ratio. The distrubition of the taxa with respect to phytogeographic regions; Mediterranean Elements %19,6, Euro-Siberian Elements %17,2, Irano-Turanian Elements %7,9 and Cosmopolitans and unknowns elements %55,2. The largest three families due to the number of taxa are as follows: Asteraceae (50), Fabaceae (50.), and Lamiaceae (30).
