Endemic plants are comparatively numerous as is to be 

 expected in an island. Tliere are as many as 99 species, or 

 25^6" of the total number of tlie plants fouud in the high 

 elevations. This richness in endemic plants seems to indicate 

 tliat the island has been entirely separate from neighbouring 

 countries since geological epochs. 



However opulent Formosa is in pecuhar plants, the figure 

 representing the number of tlie endemic species is not so large 

 in the case of tliis island as it is in that of tlie Philippines.^^ 

 This fact shows that the flora of Formosa is of continental 

 character, while that of the archipelago is insular. 



The numbers of the plants of endemic character under each 

 genera are shown in the following list.

 Forest Eeserve is endemic to the Philippines. .. .(see Philipp. Journ. Sei. Vol. I. Snppl. p. 9.)
