EXPLANATORY NOTE 
This circular is made up principally of notes received from agri- 
cultural explorers, foreign collaborators, and correspondents, concern- 
ing the more important plants which have been received recently by the 
Office of Foreign Seed and Plant Introduction. It also contains re- 
ports on the behavior of plants which have been introduced in previous 
years . 
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. 
Plant Immigrants should be considered merely an ANNOUNCEMENT OF 
THE ARRIVAL OF PLANT MATERIAL. As a rule all material is propagated 
before being distributed; this may require several years. 
The Annual Catalogue of New Plant Introductions describes briefly 
the plants available for distribution. Application for seeds or plants 
listed in Plant Immigrants may be sent at any time, however, and will 
be filed in the order of their receipt. When material is ready for dis- 
tribution, these requests will be given first attention; if their num- 
ber is sufficient to exhaust the available supply of a given species, 
it will not be included in the Annual Catalogue. 
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.
