INTRODUCTORY NOTE. 



This catalogue describes over 300 

 species or varieties of new foreign 

 plants most of which have not been grown 

 to any extent In this country. Our 

 familiarity with them is consequently 

 very limited and they are not like 

 standard seeds and plants, the behaviour 

 of which can b.e predicted with more or 

 less certainty. 



They have been Imported for trial 

 because of some direct or Indirect use 

 which It Is believed can be made of them 

 by Americans. 



They are Introduced primarily for 

 use by the Federal and State Experiment 

 Stations of the country, but are avail- 

 able to such private experimenters as 

 have the necessary facilities and are 

 desirous of testing them, notwithstand- 

 ing the fact that they are quite untried 

 commercially . 



Since these plants must ultimately 

 be grown by private Individuals before 

 their commercial success Is assured, It 

 may be well to point out that those pri- 

 vate experimenters who test these prob- 

 lematical new plants are assisting In a 

 very practical way In the plant Intro- 

 duction work of the country even though 

 they are not paid for their work." 



It Is often around the successful 

 cultivation of a new Introduction by 

 some private Individual that a new plant 

 industry begins.
