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. 



It is expected that the work will be finished in 

 six parts, making two volumes. Part I, containing 

 twenty-nine» genera in seven families, appeared in 

 1911. 



The price of each part is $2.50; they can be obtained 

 at the Arnold Arboretum, Harvard University, Jamaica 

 Plain, Massachusetts.
