recorded from that island. The references here made under each 

 species are extremely limited, as there is no space for full ac- 

 counts. Critical views regarding species already described by my- 

 self or by others, are here given. In the present work, it is my 

 desire to mention all the species recorded from Formosa, which 

 have appeared in difierent publications, since the issue of the 

 Enumeratio Plantarum Formosanarum and Flora Montana For- 

 mosae. So that, practically speaking, the present work is an 

 exhaustive supplement bringing our former publications up to 

 date. 



To mention the number of species of the flora* of the island, 

 known to us up to the present time, tliere are, in the Enumeratio, 

 1999 species belonging to 701 genera and 153 families. In my 

 FJora Montana, 392 species are mentioned belonging to 266 

 genera and 70 families ; in the present work, I have mentioned 

 735 species belonging to 343 genera and 109 families, thus 

 adding to our present knowledge of Formosan flora, 567 species, 

 72 genera and 2 families. Excluding all those species which 

 appear for a second or third time, in the above three papers, 

 the total number of the plants of the island is 2660 species 

 belonging to 836 genera and 156 families. The following list 

 shows genera added to those mentioned in our former publications. 

 Most of them are new to the flora of the island.
