EXPLANATORY NOTE. 
This circular is made up largely from notes re- 
ceived from our agricultural explorers, foreign cor- 
respondents, cooperators, and others relative to the 
more important plants whichhave been received recently 
by the Office of Foreign Seed and Plant Introduction 
of the Department of Agriculture. In it are also con- 
tained accounts of the behavior in America of plants 
previously introduced. 
Descpriptions which appear 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 requests are 
placed on file, and when the seeds or plants requested 
are ready for Experimenters, they are sent to those 
who seem best situated and best prepared to care for 
them. 
However, not all the plants described herein are 
available. Some of them on arrival are sent direct to 
Experimenters or to specialists of the Department or 
of the State Experiment Stations . The remaining plants , 
with which extensive tests in this country are desired , 
are propagated at the Plant Introduction Gardens, and 
when they are ready for Experimenters they are listed 
in the Check Lists accompanying the ANNUAL CATALOGUE 
OP NEWLY INTRODUCED PLANTS, which is sent to coopera- 
tors each autumn. It is not necessary, however, to 
await the receipt of the catalogue should an Experi- 
menter wish to apply for any of the plants here 
described . 
One of the objects of the Office of Foreign Seed 
and Plant Introduction is to secure experimental quan- 
tities of new or rare foreign seeds or plants for plant 
breeders and experimenters, and every effort will be 
made to fill specific requests.
