Spicis staminiferis subgeminis erectis oblongis subtrique- 
fris ; spicis fructiferis distigmaticis subternis cylindraceis 
erectis se@pe apice staminiferis superne acutiusculis, infima 
breviter pedunculata ; fructibus ovatis compressis acutiusculis 
ore integro et protruso glabris, squama oblonga acuta paulo 
brevioribus. 
Culm 12—20 inches high, erect and stiff, acutely trique- 
irous, quite scabrous above, leafy towards the base; leaves 
stiff, erect, linear-lanceolate, rough on the edge, shorter than 
the culm, filamentose at the sheaths ; bracts leafy, rough, line- 
ar-lanceolate, about the length or longer than the culm, auri- 
culate at the base when young ; staminate spikes two, some- 
times one, rarely three, long, triquetrous, highest pedunculate ; 
staminate scale oblong, rather obtuse, reddish brown on the 
margin, green on the keel; stigmas two; pistillate spikes 
about three, erect, subcylindric, one to two inches long, 
densely flowered, often staminate at the apex, tapering 
above, nearly black from the dark colour of the scales ; fruit 
ovate, compressed, small, rather acute above, entire and pro- 
truded at the orifice, glabrous, not persistent but falling off 
very early ; pistillate scale oblong,acute, nearly black on the 
margin, white on the keel, nearly as long as the fruit. Co- 
lour of the plant, except the spikes, glaucous green. 
Flowers in May—grows in marshes. [ have found it 
abundantin a marsh a mile north of the College. Also Penn., 
Schw. 
This species, found in England and Sweden, was first re- 
cognised in our country, by Mr. Schweinitz. It has proba- 
bly been confounded with C. acuta, which it much resembles. 
There can be no doubt however that it is a distinct species. 
Though it grows in similar situations with C. acuta, it does 
not form a bog, but spreads over the surface of the marsh. 
It differs from that species too in its colour, in the appearance 
of its spikes, in its more stiffand erect form, and in its fruit be- 
ing caducous. In the specimens which IJ have seen, the pis- 
tillate spikes are as long as, but smaller than, those of the 
European sperimens.
