forms, including 3 or 5 species. From these facts, in a 

 further paper,* we deduced some e\idence against natural 

 selection as a producer of species. In a third paperf we gave 

 the species confined to hill tops in Ceylon, producing the 

 remarkable number of 108 cases, showing that the Ceylon 

 hill tops were, therefore, like such a group of oceanic islands 

 as the Galapagos, each tending to have its own species. 



In the present paper we deal with the flora of Nammakuli- 

 kanda, the conspicuous mountam facing Hakgala, but at a 

 considerable distance away, in the eastern mountain chain of 

 Ceylon. The general trend of the mountain chains of Ceylon 

 maj' be roughly indicated by the diagram on page 217. 



Naminakuli is thus distinctlj^ out of the line of the monsoons, 

 though it may exchange plants with the lofty Haputale ridge , 

 from which it is only distant about 10 miles. All the mountain 

 countr}^ here shown is " wet," and Naminakuli is consequently 

 not nearly so isolated as Ritigala, and one will not expect 

 to find upon it so large an endemic element. That one finds 

 any at all is a very strikmg fact, when one realizes how near 

 it is to other peaks and ridges of almost equal height. 



We visited the mountain on two occasions, in March and 

 September respectively, and must express our thanks to 

 Mr. John Rettie of Glen Alpin estate, who kindly allowed us 

 the use of a bungalow which he has built upon the summit, 

 and thus rendered easy what would other^^^se have been a 

 most toilsome task. We also sent the plant collector to 

 the top on other occasions, and the result of these various 

 collections is given below : — 



1. Michclia nilagirica Zonk. A form rather distinct from 

 any in the J^Madeniya heii)arium, drying bro\\Ti, not gray, 

 beneath as well as above ; leaves oval -lanceolate to 3i in. 



2. Cardamiue africana L., at 4,000 ft. 

 .3. Viola serpens Wall. 



4. Scolopia crassipes Clos. 



5. Pitt<jsporum tetraspermum W. & A. 



6. Polygala arillata Ham. 



7. Calophyllum Walkerii Wight.
