Another interesting study is that of our na- 

 turalized plants. We have so many that thev 

 appear to invade the fields and drive^out the na^ 

 tive plants in some instances; but it is by no 

 means certain but that some deemed natura- 

 lized, were not really native. Such at least 

 must have been the case with Verbascurnhap- 

 susHypencum perforatum, Daucus caroL 

 Anthemis cotrtla. Origanum vuhare, &c 1 

 gave a long Ijst of the naturalized plants in my 



ed, while others have appeared instead out of 

 gardens. But few American plants have be- 

 come spontaneous in Europe, Phytohca decan- 

 dra and Cenotis canadensis are mentioned as 

 such; but we have received several hundreds, 

 besides some few from the Antilles and inland 

 l^ecandole has properly stated that naturalized 

 plants even when not spontaneous, but e.xten- 

 sively cultivated in tiieopen air ought to be ad- 

 ded to every general flora, and Eaton has fol- 

 lowed that advice with us. 



It appears that even previous to the discovery
