CYPERACEJE. (SEDGE FAMILY.) 
perigynia roundish-obovoid, obtuse , with conspicuous elevated nerves , 
and a distinct abrupt point, longer than the ovate pointed scale; culm, 
leaves , and sAort bracts downy. — This species was collected at Carl* 
ton House by Dr. Richardson, and is here introduced only because 
Mr. Tuckerman described it from a specimen in Sir W. J. Hooker’s 
Herbarium, which purported to have been sent from New York by 
Dr. Torrey, though probably from some misplacement of tickets. It 
has a great external resemblance to the next, but is very distinct. 
* * Staminate spike sessile, or short-stalked (except in No. 64): pistil¬ 
late spikes 2-5, erect, all on more or less exserted stalks: bracts 
longer than the culm (except in No. 64): perigynia very obtuse , with 
an abrupt and minute (or almost obsolete) point, green and some¬ 
what pellucid at maturity: pistillate scales tawny, fading to white. 
— Pallescentes. 
63. C. pallescens, L. Fertile spikes 2-3, ovoid, densely 
flowered, approximate ; perigynia obovoid-oblong , obscurely nerved , 
about the length of the scale. — Yar. undulJLta has the lower bract 
indented at the base with transverse waved lines. (C. undulata, 
Kvnze ) — Meadows, New England to W. New York. — Plant 
high, with slightly pubescent culm and leaves. 
64. C. COllOidea, Schk. Staminate spike on a long stalk; fer- 
tile 2-3, oblong , closely flowered , the lower distant; perigynia oblong- 
conic, with impressed nerves , slightly oblique at the summit, rather 
longer (or sometimes shorter) than the sharply pointed or awned 
scale; bracts not exceeding the culm. (C. tetanica, Schto. Torr., not 
of Schk.) — Moist meadows, New England to Michigan. 
65. C* gTlsea, Wahl. Fertile spikes 3 -5, oblong, loosely flow¬ 
ered, remote, and the lowest distant; perigynia ovoid-oblong, rather 
longer than the ovate awned scale. (C. laxiflora, Schk., not of Lam-) 
*—Var*. mDtica has longer cylindrical spikes, short-awned scales, and 
the leaves and bracts pale-green and glaucous. (C. laxiflora ? var. 
mutica, Torr. Gr. C. flaccosperma, Dew.) — Moist woods and 
meadows, not uncommon. The variety, with spikes 1/ —1£* I° n 8» ,n 
New Jersey ( Knieskem) and in the South. 
* * * Uppermost spike more or less pistillate at the apex (rarely all 
staminate); pistillate spikes 3-5, oblong or cylindrical, loosely 
flowered, distant, all on exserted filiform, mostly drooping stalks. 
bracts equalling or often exceeding the culm: perigynia oblong, 
with a short abrupt notched point (obsolete in No. 68), green an 
membranaceous at maturity: pistillate scales tawny or white.—

66. C. Davisfi, Schw. & Torr. Fertile spikes oblong-cyhndri- 
cal , rather thick ; perigynia somewhat contracted at each end, scarce y 
longer than the conspicuously awned scale. (C. arista ta, Dew., not o
