PREFACE. 
The following Catalogue includes only the plants, Which 
have been collected by Messrs. Le Conte, Pursh, Eddy, 
Whitlow, Edmonston, Beck, and myself—4t might have been 
enlarged by the addition of some other genera and species 
which have been naturalized and now grow spontaneously 
—*but I thought it Would be more proper to confine the 
list to those which are indigenous. It will be found that 
but a very few of the Cryptogamous tribes are here in¬ 
serted—on some future occasion it is proposed to treat of 
this class more at large. 
Where I have been unable to find in the lists already pub- 
lished, an English name for the Latin Systematick name, 
I have supplied it. Many inaccuracies will no doubt be 
found in the present catalogue, but it is hoped they are 
such as may be easily rectified by the botanist. 
JACOB GREEN.
