ON THE DISTRIBUTION OF THE FORMOSAN CONIFERS. 



47 



In order to give an exact idea how many of the Formosan species 

 the neighbouring floras have, I have made the following table: — 



Table 1.— Distribution of the Formosan Conifers in Asia. 



We see from the above table that 



Japan has 12 of the Formosan species, i.e. 70 o/ of the whole No. 



North China „ 7 „ „ „ „ 41 o/ „ 



Central China „ 10 ,, ,, „ „ 59 % „ 



India „ 1 ,, „ „ „ 6 % „ 



Japan and China have comparatively a great number of Conifer 

 species in common with Formosa. But, in Indian flora which has hitherto 

 been recognised by many botanists to have a close relation to the Japanese 

 flora, we utterly fail to find any species, except J. chinensis L., in common 

 with the flora of Japan or Formosa. 



The exploration of, as well as scientific researches in central China 1 ' 

 have opened a new epoch on the study of the distribution of the Asiatic 

 flora. The gap, which has been known to have existed between Japan 

 and India with regard to their floras, is now filled up by central China, 

 and the relation of Japan and India has become less striking than that 

 of Central China and either ; for Central China has, as we see in the 

 following table, 7 species in common with India, while Japan has only one. 

 We shall compare the flora of Formosa with those of its neighbours 

 in the following table : —
