INTRODUCTION. 



As was announced in the introduction to the third volume of this work, 

 the present volume is principally devoted to the third part of those studies 

 which have for the most part been upon new material, collected since 1912. 

 The volume contains studies, on 385 species and 8 varieties ranging from 

 the Ranunculaceoe down to the Polypodiacete. All the species of 

 phanerogamous plants are here arranged, as in the preceding volume, after the 

 system of BEXTHAM and HOOKER ; while those of vascular cryptogams are 

 arranged after the system of ENGLER and PRANTL. Of the species and 

 varieties mentioned in this work, 203 are proposed as new species and 7 are 

 regarded as new varieties of known species, while 182 are identified with species 

 which were already known as from Formosa or from other countries. No new 

 genera are x>roposed, but 23 genera are mentioned as new to the flora of the 

 island. The genera mentioned in the following list are new to us. 

 Scliizandra Phoebe Disporopsis 



Pen'ottetia Pseudixus Trillium 



Pentapanax Cyclostemon Rolidea 



Valeriana Blyxa Xyris 



Linociera Ottelia Lophotocarpus 



Micrargeria Burmannia Archangiopteris 



Pedicularis Hedychium Notholcena 



Aristolocliia Clinogyne 



Species,* genera* and families* now to be added to the flora of Formosa 

 number as many as 213 species, 23 genera and 2 families. Thus, up to the 

 present date, the total number of species of the flora, so far as known, is 

 3325 species belonging to 914 genera and 160 families. 



* It should be understood that plants outside of the island are not counted in this number, 

 although they are mentioned in this volume. ::
