Comprises chromosome counts on plants from the Balkan Peninsula only.The Balkan Peninsula area covers Yugoslavia (Slovenia, Croatia,Dalmatia, Serbia, and Montenegro), Albania, Greece (Macedonia,Thessalia, Peloponeses, the Islands, including Crete), Bulgaria.European Turkey is excluded. The richness of the Balkan flora, ca. 6500species as estimated by Turrill (1929), is due to several conditions as:1. an old flora with many species already dating from the Tertiary, 2.the changes in extent and level of the Mediterranean Sea, 3. the migration of elements from other floras, like Pontic and European, 4.the inevitable influence of man. An extensive survey of these phenomenais given by Turrill (1929), and Polunin (1980).
