INTRODUCTORY NOTE.

This catalogue describes over 300 spec-
ies or varieties of 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 experts of the United States Department
of Agriculture and by State Experiment Stations 
of the country, but many of them will
be available to such private experimenters as
have the necessary facilities and desire to
test them.

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.
