tions of the Island. The effects of the northeast monsooD are 

 more uniform, and the showers extend over the entire surface of 

 the Island. Ar. Ratnapura, lying immediately under Adam's 

 Peak, the yearly amount of rain is about 14G inches, and the 

 cumber of rainy days 228; while at Badulla, at an altitude of 

 2,220 feet, the rainfall is about 58 inches, with 57 rainy days. 

 This wide difference of climatic conditions gives suitable condi- 

 tions for species having widely differing requirements for their 

 growth, and presents a goodly list, of species as indigenious to 

 the Island. 



The majority of the species grow at an elevation of between 

 2,000 and 5,000 feet. 



The localities in the following notes are taken, principally, 

 from "A Catalogue of the Ferns Indigenous to Ceylon, by G. W.," 

 published 'in London.
