More than 80 species of Veronica genus are found in Turkey which is small region comparing to world land and the endemism rate of Veronica taxa is very high in Turkey. This suggest that Veronica taxa on the world may originate from Turkey. The richness and distibution of Veronica taxa may be affected by different factors; geomorphologic structure, climate changes in the region, specific sediments belong to geologic period, positioned in the moderate zone as a geographic situation and even paleomorphologic, paleogeographic and paleoclimatologic changes. Also, historical, ethnographical and some other natural factors have affected this distribution. In the earth, although Turkey is a small region but contains high number of Veronica taxa. Turkey is situated in the geometrical center of the disribution of Veronica in the earth.
