Pinus pinea L. (Stone pine) forests isn’t widespread on the World. From the point of view of plant geography, study area is situated in the Mediterrancan floristic region which is under the effective control of a semi-arid, and superior-lukewarm variants of Mediterranean climate. Annual rainfall quantity is very important for development Pinus pinea. The minimal rainfall must be at least 600 mm. In this study the floristic composition and diversity of Pinus pinea forests in the south-western Anatolia region of Turkey have been investigated. In the study area, 212 species belonging to 145 genera and 37 families were identified. Distribution rates of the species in terms of phytogeographic regions are as follows: 54 (25%) Mediterranean elements, 28 (13.20%) East Mediterrancan elements, 6 (2.83%) Trano-Turanian and 4 (1.89%) Euro- Siberian elements, and 121 (57.08%) multi regional elements, The number of endemic is 11 and the rate of endemism is 5.1%.
