AET. 19. — B. HAYATA : 



li) Elements of central and southern China {inclucUiKj Tibet). 



This is the class best represented in the flora, comprising as 

 many as 192 species, or 49% of the whole number. Most of 

 them are also fonnd in Japan. 



The plants wliicli are confined to this region and Formosa, 

 are as follows : — 



HcecHa Aschersoniana Enc^l. 



Gejebx. 

 Senecio monanthns Diels. 

 Petasites iricholohus Feanch. 

 Gerdiana Jmmilis Stex. 



et 



Salvia scapiformis Hance. 

 Daphne Championi Benth. 

 Llhocedrus macrolepis Benth. 

 Pimts Armandi Feanch. 

 Keteleeria Davidkma Belssn. 



They are in all 9 species, among which we have 2 

 genera, Hceckia and Keteleeria, which are fonnd in this region 

 and Formosa, but nowhere else. 



Here we see that the strong affinity between the two regions 

 is as clearly shoAvn by the plants of peculiar character as by 

 the number cf the elements. 



i) Japanese Elements. 



The Japanese elements are, next to the Chinese, best re- 

 presented in the flora. They comprise in all 163 species or 

 42% of the whole number.

 Japan, are as follows : —
