CYPERACEjE. (SEDGE FAMILY.) 
nodding spikes, many-nerved perigynium, and the longer and smooth 
teeth of the beak. The var. appears to be a depauperate (probably 
summer) form, differing in no essential character. 
109. C. tentaculata, Mu hi. Fertile spikes 2-3, ovoid, ob¬ 
long , or cylindrical , densely flowered, approximate and diverging hor¬ 
izontally, the uppermost sessile , the lower on short exserted stalks; 
perigynia spreading, tapering from an ovoid few- (about 10-) nerved 
base into a long slender beak with short minutely serrulate teeth , much 
longer than the lanceolate awned scale. (C. rostrata, Muhl., not of 
Michx.) — Wet meadows, very common. 
110. C. intumescens, Rudge. Fertile spikes 1-2, ovoid , 
loosely few - (5 - 8-) flowered , closely approximated , sessile , or the low¬ 
er on a very shortly exserted peduncle; perigynia erect-spreading , ta¬ 
pering from an ovoid 15-20-nerved base into a long beak, slightly 
rough towards the apex. (C. folliculata, Schk ., Michx., not of L.) — 
Wet meadows and swamps, very common. — Culm slender, about 
18' high, with 1-3 fertile spikes crowded together so as to be scarce¬ 
ly distinguishable : perigynia 6-7 lines long. 
111. C* Grayii, Carey. Fertile spikes 2 (sometimes single), 
globose, densely (25-30-) flowered, separate and distinct , on short ex¬ 
serted peduncles; perigynia spreading and deflexed, tapering from an 
ovoid 25 - 30-nerved base into a long smooth and shining beak. — Low 
meadows on the banks of the Mohawk and Wood Creek, New York. 
Also Columbus, Ohio, Svllivant. — Culm robust, 3^ high : perigynia 
I' in length. — Flowers a month later than the last. 
* * Bracts conspicuously sheathing. 
112. C. folliculata, L. Staminate spike small, short-stalk¬ 
ed, or often sessile ; fertile spikes 3-4, ovoid, very remote, the lower 
on exserted peduncles ; perigynia erect-spreading, tapering from an ob¬ 
long base, rather exceeding the ovate white long-awned scale. (C. xan- 
thophysa, IVahl.) — Peat-bogs, New England and southward. — A 
robust plant, 2°-4° high, of yellowish appearance, with long folia- 
ceous bracts, and leaves wide. 
113. C* rostrata, Michx. Staminate spike small, nearly ses¬ 
sile ; fertile spikes 1-3, commonly 2, roundish-ovoid, the lower rath¬ 
er distant on a short exserted peduncle ; perigynia erect, or somewhat 
spreading, tapering from an oblong slightly inflated base into a long 
slender beak twice the length of the blunt light-brown scale. (C. xan- 
thoph^sa, var. n&na and minor, Dew.) — Mountains of N. New York, 
and White Mountains, New Hampshire.— Resembles the last in 
color and general appearance j but smaller in all its parts, rigidly 
erect, with narrow leaves. 
114. c. subulata, Michx. Fertile spikes 3-5, very remote , 
on included peduncles loosely few- (4-8-) flowered , commonly with a
