44 BOTANICAL MAGAZINE. [Vol. xix. 



A few days ago, I was given by Prof. J. Matsumura a small set of 

 conifers collected by P. Torii in the year of 1900 on Mount Morrison, 

 the highest peak in the southern part of Formosa. The specimens are, 

 though very small, of special interest, as the conifers of Formosa are not 

 yet well known to botanists. Studying the conifers, I found that they are, 

 not of southern but, of northern species such as are to be found in Hok- 

 kaido, Corea and Saghalien. 



It is noteworthy that those which are to be found in such cold regions 

 also exist in the mountain of a tropical island as Formosa. This has led 

 me to work upon the distribution of the conifers, in the northern hemis- 

 phere, together with the geographical relation of Japan and Formosa in 

 former times. 



The materials upon which my work is based are as follows : — 



1) Thirty nine Japanese species. ]) 



2) Seventeen Formosan species. 



3) Eighteen species of Central China, and Corea. 2) 



Besides these specimens, I have adapted those which are taken from the 

 concerning literature. 



In conclusion, I must express my hearty thanks to Prof. J. Matsumura 

 under whose supervision this work has been executed. I also owe thanks 

 to Mr. T. Makino for his valuable advice. Nor should I forget to tender 

 my best thanks to Messrs. H. Shirasawa and S. Honda who loaned me 

 their interesting specimens. Lastly I must express the gratitude that I 

 owe to Dr. S. Tokunaga for his kind information about the geology of the 

 countries under consideration.

1) All these materials are preserved in the Herbarium, Science College, Imperial 

 University. 



2) This set of specimens is mostly due to the kindness of Dr. H. Shirasawa who was 

 so kind as to put the valuable materials at my disposal, which were sent to him from the 

 Royal Gardens, Kew, in the year of 1903. The conifers were collected by Mr. E. H. Wilson, 

 and were enumerated by Mr. M. T. Masters in the Journal of Botany, Vol. XLT. 267, 

 under the title of " Chinese Conifers collected by E. H. Wilson." What I have of these 

 are as follows: — 



Picea Alcoekiana Carr No. 1896.
