          PLANT INTRODUCTIONS. 
Experimenters will please read carefully this Introductory  
Note before sending in their requests for plant material.

This, the Fourteenth Annual List of Plant Introductions, contains 
descriptions of many new and rare plants, not yet widely tested in this 
country. The available information concerning some of them is meager, and 
it is therefore impossible to speak with assurance regarding their value, 
their cultural requirements, and their adaptability to the various climates 
and soils of the United States.

These plants have been imported because of some direct or indirect 
use which, it is believed, can be made of them. They are first placed at 
the disposal of the experts engaged in plant breeding, crop acclimatization, 
and horticultural investigations generally in the United States Department 
of Agriculture and the State Experiment Stations. Many of them have been 
grown in sufficient quantity, however, so that they can be distributed to 
private experimenters who have the facilities to test them carefully. The 
List is therefore sent to those who have qualified as Experimenters with 
the Office of Foreign Seed and Plant Introduction, and who have indicated 
a willingness to care for material sent them.

Accompanying this Annual List are complete Check Lists showing all 
seeds and plants available for distribution at the several Plant Introduction 
Gardens during the season 1925-26, and the Garden from which available. 
Applicants for material should fill out all blanks at the top of the Check 
List of each garden from which they request plants, place a mark to the left 
of the S.P.I. (Seed and Plant Introduction) number of each plant desired, and 
return the lists promptly to this Office.

It should be distinctly understood that the Office does not agree 
to supply all the plants requested. The object of the Annual List and 
the Check Lists is to place experimental material where it is thought the 
chances of success are best; to this end the experts of the Office will 
allot the available number of plants to those experimenters whose location 
and facilities seem most suitable, having in mind, at the same time, the 
order of receipt of the returned Check Lists, and giving preference to 
those which arrive first.

The shipping season extends, as a rule, from December first to April 
first. Because of the large quantity of plants which must be handled, it 
is difficult for the Office to single out individual requests and ship them 
at a certain date; where there are, however, valid reasons for requesting 
that material be sent at a specified time, every effort will be made to 
meet the requests.

These plants are placed in the hands of experimenters with the 
understanding that reports on their behavior will be sent to this Office 
from time to time. It is particularly desired that reports be sent to this 
Office regarding the flowering, fruiting, hardiness, utilization and other 
interesting features of plants which have been sent for trial; and it is
