lanceolate, shorter than the fruit, of a brownish color. Fruit ventricose, 

 strongly nerved, spreading almost horizontally, but not reflexed ; rostrum 

 rather short and straight ; orifice entire. 



Hab. On the gravelly borders of a small lake in Sussex 

 county, New-Jersey. On rocks about the Falls of Niaga- 

 ra ; on the Canada side. Prof. Dewey. Near Hudson's 

 Bay. Michaux. Flowers in June. 



Obs. This species is by many botanists considered as a 

 variety of C. Jlava, but the numerous specimens of it which 

 we have examined, uniformly differed from that plant, in 

 having the fruit horizontal, not reflexed. The spikes in 

 C. (Ederi are also much more densely flowered, and the 

 fruit but half as large as in C.flava; still it is possible they 

 may not be distinct species. In both the whole plant is of 

 a yellowish-green color.
