(Continued from p. 15.) 



Last year I continued my writing in this magazine under the title 

 of "Contribution to the Flora of Mt. Morrison"; and also wrote a few 

 times under the title of " Supplements to the Enumeratio Plantarum 

 Formosanarum. " I think now it would be better to combine the former 

 with the latter, as both subjects are in the same field of investigation. 

 In this paper, therefore, I shall try to give all my study to the botany 

 of any region of the Island of Formosa.
