Of these 28 species of Europe, 12 are Alpine, or found in high 

 northern latitudes. 



C. Ehrhartiana is found in Germany, and is probably a form of C. 

 teretiuscula Good.

 and has only been found once near Boston, U. S. A.

I can offer you little that is satisfactory to myself as to the geogra- 

 phical range of the 97 species that are common to Arctic America and 

 the States, for want of precise data as to the Carices of the Southern 

 and Western States. 



A. — I find, from such data as I have, that from lat. 30° to 35°, that is, 

 from N. Orleans through the Carolinas, there are 33 species 

 extending into Arctic America, one of which, C. Novae Angliae 

 Schwz., ranging from N. Orleans to the Arctic Sea, maintains 

 an equally vigorous development through 40° of latitude.
