338 Monograph of North American Car ices. 



Culm 2 feet high. Leaves bracteae, and sterile spike as in the preceding. 

 Fertile spikes generally 5, sometimes but 4, nearly cylindrical, 2— 3 in- 

 ches long; the three upper ones approximate and sterile, the fourth a 

 little distant on a short peduncle, the lowest rather remote, on a pedun- 

 cle 1 — 3 inches long. Fruit and glumes not perceptibly different from 

 those of C. lupulina. 



Hab. In wet meadows and swamps. Philipstown, Highlands 

 of New-York. Flowers in the beginning of June. Dr. 

 Barratt. 



Obs. This variety is very constant in its appearance. It 

 grows in the station mentioned, in great abundance, often 

 in company with the common C. lupulina. The spikes 

 are much longer, more numerous, and not so thick as in 

 that plant, but in other respects they do do not differ. It 

 resembles C. retrorsa, but the fruit is never reflexed.

Culm a foot and a half high, leafy, triquetrous, smooth, slender. Leaves flat, 

 rather broad, smoothish. Sterile spike usually on a long slender pedun- 

 cle, cylindrical ; glumes lanceolate. Fertile spikes commonly 2, (some- 

 times 3, Muhl.) but in many cases, and in particular localities, but one is 

 found, from 6 to 10-flowered, nearly globose, and about three fourths of 

 an inch in diameter ; upper spike closely sessile, lower one on a short 

 or included peduncle; on the summit of each there are a few small 

 sterile florets ; bractece foliaceous, very long ; glumes ovate, acuminate, 

 ending in a filiform point, much shorter than the fruit. Fruit ovate, re- 

 markably inflated or ventricose, very large, acuminate into a pretty long 

 beak, smooth and nerved, the upper ones spreading almost horizontally, 

 the lowest a little reflexed,
