Root fibrous. Culm about two feet high, rather slender, sharply trique- 

 trous, nearly smooth, deeply furrowed, leafy. Leaves always longer than 

 the culm, with a short abrupt sheath, furrowed, scabrous; the upper 

 ones very narrow and long; all are more or less spreading, and not erect. 

 Spike usually solitary and terminal ; frequently, however, there are two 

 and even three spikes, from one inch to two inches in length, and more 

 than half an inch in diameter, rounded above and below ; sterile florets at 

 the base of the spike, dry and decurrent on the peduncle ; glumes 

 oblong, distant, brown, with a greenish midrib not produced at the apex \ 

 > fertile glumes similar. Fruit horizontal, (erect when young) turbinate 

 and inflated below, strongly nerved and produced into a long conical 

 rostrum, which is bifid and recurved at the apex. Seed much smaller 

 than the envelope, obtusely triangular, punctate. 



Hab. In bog meadows; rather rare; June. Canada to 

 Georgia, but not in the low country of the southern States.
