EXPLANATORY NOTE. 
This multi graphed circular is largely made up from 
notes received from agricultural explorers, foreign 
correspondents, cooperators, and others, relative to 
the more important plants which have recently been 
received by the Office of Foreign Seed and Plant In- 
troduction of the Department of Agriculture; in it are 
also contained accounts of the behavior in America of 
plants previously introduced. Descriptions. appearing 
here are revised and published later in the Inventory 
of Seeds and Plants Imported. 
Applications from experimenters for plants or seeds 
described in these pages may be made to this Office at 
any time. As they are received the requests are placed 
on file and when the material is ready for the use of 
experimenters it is sent to those who seem best situ- 
ated and best prepared to care for it. The plants or 
seeds here described (except such as are distributed 
direct or are turned over to specialists in the De- 
partment who are working on investigational problems) 
are propagated at our Plant Introduction Field Stations; 
and when ready to be distributed are listed in our an- 
nual check lists, copies of which are sent to experi- 
menters in the late fall. It Is not necessary, how- 
ever, to await the receipt of these lists should one 
desire to apply for plants which are described herein. 
One of the objects of the Office of Foreign 
Seed arid Plant Introduction is to secure material for 
plant breeders and experimenters. Every effort will 
be made to fill specific requests for experimental 
quantities of new or rare foreign seeds or plants.
