Introductory Remarks. 



The investigation of the present subject was begun in the 

 autumn of LSÜO, at the suggestion of Prof. J. Matsumura, and was 

 continued more than a year. During that time I received much 

 useful advice from him, and also from Prof. R. Yatabe, to both of 

 whom I am much indebted. The object of my researches was to find 

 out what anatomical peculiarities characterize the Magnoliaceas as a 

 whole ; what distinctive characters are presented by each of the dif- 

 ferent groups included in it ; and to what extent all the species of 

 it ma\- be anatomically distinguished from one another. 



Tliese questions naturally present themselves, if we remember 

 that systematic botanists in recent times have not agreed as to the 

 limits of this family, and have treated its members in different ways. 

 Some botanists extend its province by including certain tribes not 

 usually admitted, while others restrict it by omitting triljes coui- 

 nionlv included. 8iich indefiniteness as to its extent shows that this 

 natural family is not very natural, and I hope that the study I have 

 made of its anatomical characters may Ije of some service in remedying 

 this defect.
