&c. Those two beautiful plants, for our knowledge of both 
of which, I believe, we are indebted to Mr* Nuttall, the As_ 
ter sericeus . and Amorpha canescens , are very generally dif¬ 
fused, but not in the same abundance with many others. In¬ 
deed, they constitute an exception to the habit of congrega¬ 
tion which obtains among so many of their associates. 
As is the case, I believe, with the American Flora through¬ 
out -the United States, and indeed, the whole Continent, the 
autumnal botany of the prairies exhibits a large preponder¬ 
ance of the Comoositae . Besides those already mentioned, we 
may here enumerate, as of frequent occurrence, Chrysopsis 
mariana, Helenium autumnale, Boltonia glastifolia and J3. .as- 
teroides, Bidens frondosa and B. chrysanthemoides , Eupatorium 
serotinum, E. aromaticum 5 E. ageratoides E. . piirpur eum, 
"ET perfo liatum , &c., Cnicus glutinosus , Virgin . 1 y ill

p. racemos~a , P. serp ent aria , &c., Vernonia fasciculata, 
corymbosa , and one or two other species. 
In a farmer T s, or rather a grazier ! s estimation, the grasses 
would be regarded as the most valuable of the natural Pro¬ 
ductions of the prairies; and we will next mention some of 
l&ster laevis, JU Novae Angliae, A-. rigid ug, Aj. As.
