FI.ORA MONTANA FORMO.S.E 33 



Thus, I divided the Chino-Japanese flora into two floriilje, one is 

 the central florala, the other, the border flornla. 



Kegarding the present subject of the montane flora of the 

 island, I see that mjr former conclusion will liold equally good 

 of the formation of this flora. 



Taking all these cases into account, I have come to the 

 conclusion that the similarity of the floras of Formosa and 

 Japan may have been caused, on the one hand, by the existence 

 formerly of a land-mass between the islands, and, on the other, 

 by the same insular conditions caused by the depression forming 

 tlie inner seas in more recent geolooical ao-es. 



3) General Aspect of the Vegetation. 



The vegetation of the montane zone of Formosa varies 

 considerably according to the height. As Mt. Morrison presents 

 various climatal features from subtropical through temperate up 

 to cold regions, the vegetation of this mountain will give us 

 a fair idea of the general aspect of the growtli in the liill 

 regions of the island. 



As I have already mentioned, a botanical t'xcursion was 

 carried out on the mountain by Messrs. T. Kawakamf, 8. Naga- 

 SAWA and G. Nakahaka, and a report'^ of the journey was 

 published by Mr. T. Kawakami in the Tokyo Botanical ^Magazine. 

 As his report is the only publication relating to tliat mountain, 

 I take the liberty of drawing some descriptions from it. 



It was on the 28tli of October, 1905, tliat tlie party left 

 Kagi, a small town on the north-western foot of the mountain.
