northern hemisphere. Another case of novelty is the addition of 

 two famihes to the present flora. They are Hernandiacese and 

 MyristicoDe. 



The materials upon which this work is based are, in greater 

 part, the collections made by the Governmental Botanical Survey, 

 supervised by Mr. T. Kawakami, during 1906-1909. I have also 

 referred to a small set of specimens of Loo-chooan plants, collected 

 by Mr. G. Nakahaea, a few dubious specimens from the Loo- 

 choo and Benin islands, preserved in the Herbarium at Tokyo, 

 and small collections of Formosan plants sent by Mr. S. Nagasawa 

 and the late N. Konishi. 



The present work was, in great part, carried out by myself 

 in the Herbarium at Kew. A few families were examined by 

 the staff of the same laboratory. Of the staff, 1 may mention 

 Dr. 0. Stapf for doubtful families, Mr. E. N. Beown for Ascle- 

 piadeas and Aroidese, Mr. E. A. Eolfe for Umbelliferae and 

 some Orchids. 



In conclusion, I must tender my hearty thanks to Prof. 

 J. Matsumuea for his encouragement during the present w^ork. I 

 also wish to express my sincere gratitude to Mr. K. Oshima, 

 Ex-Chief of Civil Government of Formosa, by whose graciousness 

 extended towards myself, I was able to visit the principal herbaria of
