Culm generally about a foot high, erect, slender, triquetrous, leafy, smooth. 

 Leaves erect, rather glaucous, the upper ones longer than the culm ; 

 lower ones abbreviate ; sheaths white and membranaceous on the inside. 

 Sterile spike about three fourths of an inch long, usually closely sessile 

 at the base of the upper fertile spike, which it scarcely exceeds in length, 

 fructiferous at the summit: glumes ovate, acute or obtuse. Fertile 

 spikes 3 or 4, about an inch long, cylindrical and densely fruited ; the 

 uppermost one sessile, the next on an exsert peduncle, the lowest long- 

 peduoculate ; glumes broad-ovate, membranaceous, acuminate, shorter 

 than the fruit, carinate. Fruit roundish-ovate, somewhat ventricose? 

 strongly nerved, with a very short somewhat gibbous aud recurved 

 rostrum. 



Hab. In wet meadows ; Canada to Pennsylvania ; common. 

 Flowers in May. 



Obs. Whole plant at first glaucous ; in maturity the spikes 

 are dull orange-yellow. It is usually about a foot high, 

 but in favorable situations it is often much taller. We 

 have specimens from Dr. Holmes of Montreal, collected by 

 that gentleman in Lower Canada, in which the terminal 

 spike is androgynous.
