Contributions to the Knowledge of the 

 forest Flora of Japan. I, 



By 

 M. Shirai. 



{With PLV.) 



In the course of studying Japanese forest flora, I have met with 

 many species of trees which were imperfectly described by the old writers 

 and also with those entirely new, some to Japan and others to the world. 

 But as trees are of large size and easy of detection, our botanists have 

 already done so much toward their discrimination, that there remains but 

 a few species to be newly discovered. Of the many imperfectly known 

 trees, species of salix and Bamboos are the two large groups which require 

 some renewed and careful study. 



In the following paper, I intend to describe and illustrate such new 

 or rare species of trees as I had the opportunity to examine during the 

 last ten years, an interval of time during which I have spent almost every 

 summer for botanical excursions throughout the empire except Formosa and 

 Luchoo, in order to collect specimens for my study. All the illustrations 

 rough as they are were made with my own pencil from the natural sped-
