It is very probable that the inflorescence of this species, from 
the existence of sterile bracts on the culm, may be found to be 
more composite than on the specimens figured, which are the 
only ones I have seen. Its affinity is with C. leucantha , Arn.

The small, very inconspicuous male spike often surpassed by all 
the spiculse, the minute dark-coloured perigynium, the shorter 
delicate culm and leaves, sufficiently distinguish the American 
from the European plant. 
The specimens figured are from Germany.
