PLANTAE WILSONIANAE 



In this work it is proposed to give an enumeration 

 of the dried plants collected by Mr. E. H. Wilson 

 during his expeditions to western China in behalf 

 of the Arnold Arboretum, with descriptions of new 

 species and the elaborations of certain genera as rep- 

 resented in the Chinese flora. 



The work will be finished in nine parts, making three 

 volumes. The price of each part is $2.50; they can 

 be obained at the Arnold Arboretum, Harvard Uni- 

 versity, Jamaica Plain, Massachusetts. 



COLLECTION OF 

 WILSON'S PHOTOGRAPHS 



The photographs mentioned in this work may be 

 obtained from the Arnold Arboretum, Harvard Uni- 

 versity. The pictures, taken by Wilson in China with 

 a full knowledge of his subjects and their scientific 

 importance, give for the first time an accurate idea of 

 trees and different types of vegetation found in western 

 China. The pictures taken in Japan form an important 

 contribution to the knowledge of the vegetation of 

 that country.
