CYPEBACEJE. (SEDGE FAMILY.) 
122. C. anipullacea, Good. Staminate and fertile spikes 
2-3, most frequently 2 of each, oblong or long-cylindrical, remote, ses¬ 
sile, or the lower on short and smooth sometimes nodding stalks, the 
lowest loosely flowered at the base ; perigynia roundish-ovoid, about 
17-nerved at the base and 10-nerved at the apex, abruptly contracted 
into a short cylindrical beak; scales lanceolate, aimless, or the upper 
with a rough awn shorter than the perigynium; culm slender, obtusely 
angled, smooth; leaves and bracts glaucous, often involute, longer 
than the culm. — Var. utriculata. Staminate spikes 3-4; fertile 
usually 3; perigynia oblong-elliptical, tapering ; scales lanceolate, ta¬ 
pering, terminated (especially the lowest) by a long rough awn ; culm 
stout, spongy at the base, smooth or rough towards the summit; 
leaves and bracts glaucous, wide and much longer than the culm. (C. 
utriculata, Boott.) — Common northward, and from Arctic America to 
the Pacific. — Differs from the 2 last in the smooth obtuse-angled 
culm, glaucous leaves, and particularly by the awned scale. The 
var. is the prevailing form in the United States, and is a larger and 
stouter plant; but the characters derived from the more elliptical 
fruit, and awned lower scale, do not appear sufficiently constant to 
separate it from C. ampullacea, into which it insensibly passes, as Dr. 
Boott has himself remarked in his elaborate exposition of this and the 
allied species. 
123. C. cylindrical Schw. Staminate spikes about 2; fertile 
spikes 2-3, commonly 3, oblong or cylindrical, stout, somewhat ap¬ 
proximate, on rough stalks, the lowest often nodding; perigynia thin 
and transparent, much inflated, oblong-ovoid, obliquely erect, tapering 
into a rather abrupt long-cylindrical smooth beak, much longer and 
broader than the ovate pointed or rough-awned scale; bracts very 
long and, like the narrow leaves, rough and exceeding the rough culm. 
(C. bullata of American authors generally, not of Schk. C. Tucker- 
mini, Dew., Boott.) —Swamps, W. New York and westward. — Dif¬ 
fers from the next principally in the more numerous and longer fer¬ 
tile spikes, larger, more inflated and membranaceous ascending fruit, 
with smooth beaks. 
124. C. bullata, Schk. Staminate spikes 2 - 3; fertile spikes 
1-2, most frequently 1 , approximated, oblong or cylindrical , stout, ses¬ 
sile or on short smooth stalks; perigynia spreading, ovoid, tapering 
into a long-cylindrical rough beak, much wider and longer than the 
obtusely-pointed lanceolate awnless scale; bracts and leaves narrow, 
about the length of the smooth or roughish culm. (C. cylindrica, 
Tuckerman, Torr. JY. Y. St. FI. (excl. syn.), not of Schw.) — Wet 
meadows, New England, New York, and Penn. — Well distinguish¬ 
ed from the last by the short and stout, commonly solitary fertile 
spike, which has a squarrose appearance at maturity from the widely- 
spreading fruit, of which the beak is minutely, but distinctly, serrulate.
