PREFACE. 



T. 



HE following Catalogue includes only the plants, which- 

 have been collected by Messrs. Le Conte, Pursh, Eddy, 

 Whitlow, Edmonston, Beck, and myself it 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. .
