4. Naturalized plants, spreading with the progress of civilization: of these we 
have in de neighborhood of St. Louis, Taraxacum Dens-Leonis, Marrubium cul- 
gare, Trifolium repens, Bromus secalinus, Verbascum Tha; and V. Blattaria, 
(perhaps belonging to the third class,) Vepeta Cutaria, Arctium minus, etc. Cicho- 
um Intybus, Echium vulgare, and others, I have not seen in the west. 
oe oy is difficult to decide to which of these classes Datura Stramonium and Portu- 
Pig lacce oleracea should be referred, Datura is perhaps introduced in Europe as well 
3 as America, and possibly did not reach this country from Europe. Erigeron Cana- 
2 and biennis are now as widely naturalized in gale r'- as Taraza- 
 panitd ig Aanerica.
