INTRODUCTION. 



Towards the close of the last century, the flora of Formosa 

 has been studied by many botanists, such as Hance, Hemsley, 

 Maximowicz and others, and there are several publications relat- 

 ing to it. One of these publications, Forbes and Hemsley's 

 "Index Flora? Sinensis," includes many Forniosan plants; but 

 this cannot be considered as satisfactory accounts of the Formo- 

 san flora, as many important species are not mentioned and the 

 higher Cryptogams, such as ferns, are entirely omitted. At jirc- 

 sent,HENRY's " List of Plants from Formosa " is the only book 

 which can be looked upon as a guide for students of tlu' For- 

 mosan flora. In tliis he enumerates l'J'.>7 species of Phanerogams
