BOTANY. 
Art. Vil.—Contributions towards the Botany of the States of 
Llinois and Missouri. By Lewis C. Beck, M. D. Profes- 
sor of Botany, Mineralogy, &c. in the Rensselaer School. 
TO PROFESSOR SILLIMAN. 
Draw Siz, 
Durine my residence in Missouri, in the years 1820, Pals 
and 22, a portion of my time was occupied in the investi- 
gation of the vegetable productions of that and the adjoining 
state. Upon my return, I was so fortunate as to receivé, un- 
injured, the collections which [had made. Until the present 
season, however, [ have not had leisure to examine them with 
the necessary attention, and to revise my notes upon the re- 
cent plants. This work I have now commenced, and submit 
to you the first part, for publication in your valuable journal. 
Those species which are presented as new, are minutely 
described ; and in all cases where the western specimens of 
known plants differ from the eastern, this difference is 
stated. By this means we shall become acquainted with, at 
least, some of the peculiarities in the vegetation of that inter- 
esting section of the United States. Concerning the more 
common plants, the habitats and times of flowering only are 
mentioned. The catalogue, it is hoped, will contribute some- 
what to increase our stock of knowledge, and will be particu- 
larly interesting to geographical botanists, and to future wrie 
ters upon the botany of the United States. 
With sentiments of respect, 
| Yours, &c.
