THE PALMS OF BRITISH INDIA AND CEYLON. 45 



only 14 species are known to occur. Several genera have been found 

 in the Pacific Islands. 



Drude has shown that, with the exception of three genera, all the 

 rest are restricted either to the Old or to the New World. Of those 

 three the Cocoa-nut has a wide distribution on the coasts of tropical- 

 America, in India and the South Seas, but all its allies are American. 

 The Oil-palm (Elceis guinensis) is indigenous in western tropical 

 Africa, whilst another species of the same genus is a native of equa- 

 torial Africa. One species of Raphia belongs to America, whilst 

 several others have their original home in tropical Africa and 

 Madagascar. 



The following table gives all the genera of palms with the number 

 of species and their distribution. An asterisk indicates that the genus 

 is represented by indigenous species in India and Ceylon: two 

 asterisks, that representatives of the respective genus are cultivated 

 in Indian gardens.
