EXPLANATORY NOTE 
PLANT IMMIGRANTS is designed principally to call the attention of 
plant breeders and experimenters to the arrival of interesting plant 
material. It should not he viewed as an announcement of plants available 
for distribution, since most introductions have to be propagated before 
they can be sent to experimenters. This requires from one to three years, 
depending upon the nature of the plant and the quantity of live material 
received. As rapidly as stocks are available, the plants described in 
this circular will be included in the Annual List of Plant Introductions, 
which is sent to experimenters in late autumn. Introductions made for a 
special purpose (as for example to supply Department and other specialists 
with material needed in their experiments) are not propagated by this Office 
and will not appear in the Annual List. 
Descriptions appearing here are revised and later published in the 
Inventory of Seeds and Plants Imported, -the permanent record of plant in- 
troductions made by this Office. 
Plant breeders and experimenters who desire plants not available 
in this country are invited to correspond with this Office which will 
endeavor to secure the required material through its agricultural ex- 
plorers, foreign collaborators, or correspondents.
