Mountainous Vegetation of Central Black Sea Region

Central Black Sea Region includes many different vegetation types. At high elevations, forest vegetation is dominant. Some forest types have closed canopies, while some of them can be disturbed mainly due to anthropogenic factors (grazing, clear-cutting, etc.). Oceanic climate is seen in northern slopes, while continental climate is also seen especially in inner parts of the region. Continental climate is also seen in inner parts of stream valley (e.g., Kizilirmak valley). Mediterranean climate is also penetrated in inner parts of the region. As a result of this, it is impossible to draw a demarcation line among different vegetation types. For example, some forest communities include Euxine, steppe, and Mediterranean-type communities and phytosociological classification is too difficult.

Draba cemileae (Brassicaceae), a New Species from NE Anatolia, Turkey

Draba cemileae Karaer sp. nova (Brassicaceae) is described and illustrated. It is confined to NE Anatolia in Turkey. The diagnostic morphological characters from closely similar species in the sect. Chrysodraba are discussed. Notes are also presented on its ecology and biogeography. The ultrastructure of the seed coat surface of D. cemileae and the similar species was examined by SEM.
