- Due to its geological positions, Turkey contains different phytogeographical regions and had possible refuge regions for many plants and animals during the glacial periods. According to Davis a major flora boundary occurs in Turkey, along a diagonal belt running from NE Anatolia (S of Gümüşhane) to SW Anatolia, where it splits out the Cilician Taurus and Amanus mountains. The geographical distribution of Turkish <i>Quercus</i> L. taxa and their relations with the diagonal have been discussed. Only nine taxa out of 23 showed clear separations on the basis of the Anatolian Diagonal, which are <i>Q. petraea</i> subsp. <i>iberica, Q. petraea</i> subsp. <i>pinnatiloba, Q. robur</i> subsp. <i>robur, Q. robur</i> subsp. <i>pedunculiflora, Q. pubescens, Q. ithaburensis</i> subsp. <i>macrolepis, Q. brantii, Q. trojana</i>, and <i>Q. libani</i>. Beside the distribution of Turkish <i>Quercus</i>, the refuge regions mentioned by Davis and the potential palaeogeographical history of the Anatolian Diagonal have also been considered in detail.
