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 be 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 available 
to such private experimenters as
have the necessary facilities and are
desirous of testing them, notwithstanding 
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 private 
experimenters who test these problematical 
new plants are assisting in a
very practical way in the plant introduction 
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.
