The genus is confined to the Old World in the northern hemi- 

 si^here, mainly between 9° west and 50° east longitude, and 31° 

 north, and 48° north latitude. There are also in Central Asia C. 

 alatavicus and C. Korolkowi far to the north-east of the general area 

 of occurrence. 



The area of distribution would roughly centre round the 

 Mediterranean and Black Sea, though the genus does not form an 

 essential feature of what is known as the Mediterranean Flora, 

 many of the species ascending to high ranges of altitude. The 

 district including Greece, the Greek Archipelago, and Asia Minor, 

 must be looked upon as the metropolis of the genus.
