Remark- — To avoid misunderstanding, it is to be 'noted that the genus Sasa 

 may not necessarily be regarded as a direct descendant of Arundinaria japonica. 



Sasa ramosa, which we include provisionally in our new genus, resembles, 

 however, Arundinaria Simoni in its floral characters, and has often less 

 stamens than 6. ]) Further study will decide whether it represents the type 

 of a distinct genus or not. With the erection of our new genus the dis- 

 tinction between the Arundinarieije and Eubambusere in the older 

 sense 2; becomes naturally less sharp, and we believe that the root- 

 structure, as a definite and easily accessible taxonomic charac- 

 ter, will serve hereafter, along with floral characters, the 

 purpose of a rational classification of the Bambuseaa. 



In conclusion, we wish to express our sincere thanks to Professor J. 

 Matsumura, and also to Professor M. Miyoshi, for their kind advice 



and helpful suggestion.
