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 be 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 experi- 
menters in late autumn. Introductions made for a special pur- 
pose (as for example to supply Department and other special- 
ists with material needed in their experiments) are not prop- 
agated 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 introductions made by this 
Office.
