Introduction. 



Since the publication of the Enumeratio Plantarum For- 

 mosanarum'-* and Flora Montana Formosse/^ a large number of 

 collections has been sent to me for determination, by the Go- 

 vernment of Formosa. The collections are in greater part from 

 the mountainous regions of the island and contain a considerable 

 number of novelties. As the flora of Formosa has a close 

 affinity to the floras of Japan and China, it is very important, 

 in order to work up the materials, to make an exhaustive com- 

 parison of the collections with specimens from the two countries.
