::<>_' wii.ii>: thk flora or ritioala : 



The Ceylon Bora being derived from at least three sources, 

 Malayan, Indian, and African types being all present in it. 

 forms a much more complex problem than the flora of the 

 summit of Ritigala, which is pretty evidently, with tin* excep- 

 tion of the Glochidion, derived from that of the hills only 

 forty miles to the south, and I hope to deal with it, and with 

 the floras of other oceanic islands, in more careful statistical 

 detail in a subsequent paper.
