JET. 20.] TO JOHN TORREY. 35 



BKIDGEWATER, 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 valua- 

 ble package of plants which was duly received a few 

 weeks afterwards. In the course of the ensuing sum-

 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 grateful for any 

 favors you may have in your power to confer upon 

 him. I shall be engaged the ensuing summer at Fair- 

 field and at Salina, where I hope to make some in- 

 teresting collections in natural history. If 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 a var. of C. 

 lupulina ? 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 medi- 

 cine under circumstances which will altogether
