ISTEODUCTION. 



INTRODUCTION 



In tho first ;uid secoud fascicles of tliis work, 1 treated all 

 Formosan plants bclonging to families from tho Eanunculaceae 

 to thc Dipsaccte, and it was my desirc to treat thc remaining 

 famihcs in thc presout vohimc so as to completc thc flora iu tho 

 rather compact form of a conspcctus. Bat the new materials with 

 whicli I have been loaded down sincc last year, and especially 

 thc collections uiadc by myself in my two excursious to the 

 island (in 191 '2) are so numerous that it has required my whole 

 time to work up even the lirst part of them, and this has 

 compellod mc to put off, for some years, the continuation of thc 

 consixictus appearing in the preceding fascicles. The present 

 volume is, therefore, almost wholly devoted to the results of a 

 study of the materials which have been worked up since last 

 year, aud the results are here given under the heading, " Contri- 

 butions to tlio Flora of Formosa I."' AIl the species are herc 

 arranged, as in the precoding volumcs, after the system of Benthaji 

 and HooKER. 



The collections above referred to are really considerable, and 

 it will apparently tako my wholo time for nearly two years more 

 to work them up thoroughly. Consequently it is probable that 

 two more volumos will be required to present the results of in- 

 vestigations of the raaterials which are now on my hands. The 

 eonspectus mentioned above will, therefore, I trust, be continued 

 by 1915.
