and strongly nerved perigynium, which is three to four times 

 longer than the very narrow and muticous scale. In some of its 

 forms it strongly suggests C. trichocarpa, Muhl., var. aristaia,

The study of much material leads me to separate this American 

 species from the European C, vaginata, Tausch. I have also 

 seen C. vaginata growing in Scotland, and again in Germany; 

 the American species in its native woods is familiar. When 

 our species was first discovered in the United States, by J. A. 

 Fame, in 1865, Professor Dewey drew characters of separation 

 between it and the European plant, but with the meagre material 

 at his command, elevated the distinctions only to varietal value. 



From the European plant, C. saltiicjisis is separated by its much 

 more slender and less caespitose habit, narrower leaves and less 

 conspicuous sheaths, its alternately- flowered spikes, and its much 

 smaller, less inflated, and conspicuously nerved perigynium.
