Considering that any of these species could reach the to]) of 

 Naminakuli b^^ easy stages, the hill being joined by hill tops 

 at an average level of 5,000-5,500 ft. to the other high 

 summits of the montane zone (it is itself 0,680 ft. high), to 

 discuss the methods of transport in detail would be futile. 

 It \\ill suflice lo call attention to the fact that on the extieme 

 summit, which is isolated by some miles from others even 

 nearly as high, there occur one endemic species, Smilax 

 Jh'lliana, and one endemic variety, Ptcdrantkus Gardneri, 

 var. JowHiii, besides small vaiiations in quite a number of 

 speeies. The Smilax may In- bird-carried, but the Plectian- 

 lluis must ])robably have come l)y easy stages, and developed 

 the new vaiiety as it ascended the higher summit levels of 

 the mountain from the point where it first arrived. 



There is thus evidence to sujjport the views to which 

 expression was given in the paper on Ritigala fiom the facts 

 observed on this comparatively little isolated mountain.
