"One of the Vignect. perhaps allied to C. tenella, Schk. ; very slender 

 but stiff, half a foot high, both leaves and culm tiliform and smooth; 

 epikes two or three, each bearing from one to three flowers, closely 

 aggregated into a very small and apparently monostachyous head, 

 evidently staminate above ; perigyniuni short-ovate, turgid, flat on the 

 inner face, marginless and nerveless, dull brown, beak entire or nearly 

 so. as long as or longer thaii the thin hj-aline scale.'' Collected on the 

 Saskatchewan Plains, near Fort Carleton, in August, 1872. Col. Olncy
