/:) Elcvtzcnts of central and southern China^ {inchiding Tibet). 



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

 many as 102 species, or 4.Q% of the whole immber. Most of 

 them are also found in Japan. 



The plants wliich are confined to this region and Formosa, 



are as follows : — 



Hœclàa Ascliersoniand Engl, et 



Gr.ïbx, 

 Senecio monanthis Diels. 

 Pelasites iricliololiis Fbanch. 

 Gerdiana livmilis Stea'. 



Salvia scapiformis Hange. 

 Da [line C/iamjnoni Benth 

 Lihoccdrus macrolepis Benth 

 Pimts Armandi Fbanch. 

 Keteheria Daiidiana Beissx. 



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

 genera, Hœckia and Keteleeria, which are found in this region 

 and Formosa, but nowhere else. 



Here we see that the strong aftinity between the two regions 

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

 the number cf the elements.
