CYPERACEiE. (SEDGE FAMILY.) 
84. C. Vilria, Muhl. Sterile spike sessile; fertile 2-3, mostly 
3, distinct, on very short stalks, ovoid, 6-10 -floicered; the lowest, and 
sometimes the 2 lower, with green leaf-like bracts ; perigynia obovoid , > 
with an abrupt distinctly toothed beak about the length of the ovate 
pointed light-brown scale. (C. Pennsylvdniea, var. Muhlenbergii, 
Gray , Gram, Cyp.) — In similar situations with the last, which it 
closely resembles; but has wider, shorter, and more rigid glaucous 
leaves. 
85. C. priCCOX, Jacq. Sterile spike club-shaped ; fertile 2-3, 
oblong-ovoid, aggregated near the base of the sterile spike , sessile, or 
the lowest sometimes on a very short stalk, with a leaf-like bract 
scarcely exceeding the spike ; perigynia ovoid-triangular, attenuated at 
the base, with a short beak and nearly entire orifice, about equal to the 
ovate pointed dark-brown scale ; achenium obovoid with a prominent 
ring at the apex surrounding the base of the style. (C. verna, Villars , 
Dew., not of Schk.) —Rocky hills, Salem and Ipswich, Massachusetts: 
introduced. Plant 3'-6' high, with short, rather rigid leaves. 
86. C* pubescens, Muhl. Sterile spike usually sessile ; fer¬ 
tile 3-4, oblong or cylindrical, loosely flowered, somewhat approximat¬ 
ed, or the lowest a little remote, on a short stalk, with a narrow leaf¬ 
like bract about the height of the culm; fruit ovoid-triangular, downy , 
attenuated at the base, with an abrupt slender beak nearly entire at the 
orifice , a little longer than the ovate abruptly pointed white scale ; 
culm and leaves clothed with soft hairs. — Moist woods and meadows, 
New England to Ohio. — Though related to the other species of this 
section, the present differs from them in its greater size and in aspect, 
and especially in the sharply angled perigynium. 
§ 7. Perigynia slightly inflated, with a short beak, terminating in an 
entire or slightly notched orifice: staminate spike solitary, stalked 
(in No. 87 usually pistillate at the summit): culms tall and leafy .— 
Anomaly.* 
87. C. miliacea, Muhl. Staminate spike commonly fertile 
at the summit; fertile spikes 3, cylindrical, rather slender, loosely 
flowered at the base, on filiform nodding stalks ; bracts exceeding the 
culm, with short or nearly obsolete sheaths; perigynia ovoid-trumgu- 
l&r, very smooth and thin, with an entire or very minutely notched 
orifice, longer than the ovale shortly-awned white scale. (C. prasina, 
Wahl.) — Rills and wet meadows, N. New England to Penn, and 
southward. — In aspect this species somewhat resembles the smaller 
short-awned forms of No. 49, with which it has points of affinity, 
though differing materially in the 3 stigmas and triangular fruit. 
* The species here combined, merely to avoid the multiplication of small sec¬ 
tions, do not constitute a natural group, but present certain points of affinity with 
several others.
