£7. 20.] TO JOHN TORREY. 35 
Brivcewatek, April 6, 1832. 
Having a convenient opportunity of sending to you, 
I improve it to acknowledge the receipt of your letter 
of October 6, and of the very interesting and yvalua- 
ble package of plants which was duly received a few 
weeks afterwards. In the course of the ensuing sum- 
mer, I shall be able to supply you with an additional 
supply of most of the plants mentioned in your list. 
Many of these were collected during an excursion to 
the western part of the State, and are not found in this 
section of the country.

interesting plants to you. I think he will be able to 
furnish you with many interesting plants from that 
section of country, and I shall be gratefy] for any 
favors you may have in your power to Confer upon 
him. I shall be engaged the ensuing swmer at Fair- 
field and at Salina, where I hope to make some in- 
teresting collections in natural history. Ig it is not 
too much trouble and the specimen is within your 
reach, may I ask further information with regard to 
No. 34, in my last package to you. It is a Carex, 
from the shore of Lake Erie, — growing with C. lu- 
pulina but flowering later. Is it not @ yar- of C. 
lupulina 7 ? from which it appears to differ principally 
in its pedunculate spikes? It flowers a month later 
than C. lupulina (August 6). 
Will you excuse me for troubling you on another 
subject? I shall not be able to remain much longer 
in this place, unless I engage in the practice of adh 
cine under circumstances ne will altogether pre-
