1 Though this species is enumerated in Nuttall's Catalogue, I doubt that it belongs to Arkansas. 



a Of this genus, which in the Southern States contains seventy-five species at least, M. Nuttall men- 

 tions only seven species in his catalogue, with this remark: "and many others.'''' As late in the 

 autumn, when I visited Arkansas, the species of this genus have entirely disappeared, the catalogue is of 

 course incomplete for the genus Carex. Most of the species enumerated in Chapman's Southern Flora 

 belong also to Arkansas. I have copied only the short list of M. Nuttall. 



3 Itather a Northern species. Can scarcely be found in Arkansas. 



4 Appears rare in Arkansas. It is greedily eaten by cattle, but generally grows in too deep water. 

 Its grain is gathered by the Indians and used for food.
