 This is a good species, to be separated from C. saxatilis, its 



r 



nearest ally, by the characters which have been already pointed 



out : Perigynium nearly lanceolate, gradually long-pointed and 



spreading, possessing none of that shiny, papery and inflated 

 appearance so characteristic of most of the Vesicariae; scales 

 much longer and acute or muticous; lower spike on a short but 

 slender peduncle. Ungava Bay, Labrador, Turiier ; British 

 Columbia, Rothrock^ to Alaska.

It is singular that modern botanists have overlooked the fact 

 that Schkuhr's figure of Carex varia is the C, E^mnonsii of 

 Dewey. This species was sent to Europe by Muhlenberg under 

 a MS. name, and the specimenswere divided among Wahlenberg, 

 Willdenow and Schkuhr. These specimens are unmistakably 

 the plant defined by Dewey as Carex Emmonsii,
