FLOKA MONTANA FOIîMOS.E 33 



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

 the central floriila, the other, the border florula. 



Regarding the 2^i*6sent subject of the montane flora of the 

 island, I see that my former conclusion will hold equally good 

 of the formation of this flora. 



Tating 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 

 the inner seas in more recent geological ages. 



3) General Aspect of the Vegetation. 



The vegetation of the montane zone of Formosa varies 

 considerably according to tlie height. As Mt. Morrison presents 

 various climatal features from subtropical through temperate up 

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

 a fair idea of the general aspect of the growth in the hill 

 regions of the island. 



As I have already mentioned, a botanical excursion was 

 carried out on the mountain by Messrs. T. Kawakami. S. Naga- 

 SAWA and G. Nakahaea, 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 that mountain, 

 I take the libert}' of drawing some descriptions from it. 



It was on the 28th of October, 1905, that the party left 

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