,288 Monograph of North American Carices. 



great, there can be little doubt that many species still remain 

 to be discovered. Very few have yet become known from 

 the swamps and mountains of the southern states, merely, we 

 have reason to believe, from want of attention at the proper 

 season. The botany of the northern mountains of New- 

 Hampshire and Vermont, is only beginning to be examined. 

 Very large acquisitions may be expected when the cold 

 regions of North America shall be carefully explored ; for 

 they doubtless contain as many species of this genus as the 

 similar regions of Europe, which are found to be so remarka- 

 bly fertile in them, i It is, however, probable that most of 

 them, and of the alpine species generally, will be found 

 identical with the European ones of a similar climate. 



I shall now proceed to give a conspectus of the whole ge- 

 nus and its analytical subdivisions, enumerating under each, 

 all the species of which I have any knowledge, either from the 

 books to which I could obtain success, or from actual speci- 

 mens, and then give the history of such species as have fallen 

 under my observation, at length, with shorter ones of such as 

 I have not examined, but which appear to be sufficiently 

 authentic. At the end of the work a list of the doubtful 

 species will be given. As regards synonymy, it is hoped the 

 monograph will be full enough for all useful purposes.
