33. C. tentaculata, Muhl. Pistillate spikelete 2 or 3, cylin- 

 dric-oval, or oblong, dense-flowered, the upper ones approxi- 

 mated, sessile, the lowest a little distant, on a short scarcely 

 exserted peduncle ; perigynia ovoid, ventricose, spreading, about 

 twice as long as the linear-oblong awned scale, the beak wifh 

 minutely serrulate teeth. 



TENTACULATE, OR MANY-BEAKED CAREX. 



Plant yellowish green. Culms 12 to 18 inches high, leafy. Leaves lance-linear, 

 the upper ones, or bracts, very long. Slam, spikdet % to an inch and a half long, 

 with a filiform or lance-linear bract at base, and on & peduncle % an inch to % in 

 length. Pistillate spikelets 1 to 1% inches long, diverging somewhat horizontally. 

 flab. Swamps, and wet low grounds : common. Fl. June. Fr. Aug. 



Obs. This, and the preceding species, have much general re- 

 semblance ; but the pedunculate, nodding spikelets, of the former, 

 will readily distinguish it from this one. 



34. C. intlimescens, Rudge. Pistillate spikelets 1 or 2, sub- 

 globose, loosely few-flowered, when 2, closely approximated, the 

 upper one sessile, the lower on a short peduncle ; perigynia conic- 

 ovoid, much inflated, erect-spreading, about twice as long as the 

 lance-ovate cuspidate scale. 



SWELLING, OR INFLATED CAREX. 



Culms 1 to 2 feet high, rather slender, leafy. Leaves lance-linear, the tipper 

 ones, or bracts, much surpassing the culm. Stam. spikelet \% inches long, slender, 

 on a peduncle 1 to 2 inches in length. Pistillate spikelets % of an inch long, and 

 as much in diameter, 5- to 8-flowered ; perigynia about % an inch long. 

 Hab. Wet, miry places : frequent. Fl. June. Fr. Aug. 



t f Bracts cvnspicuouxly sheattnng. 



35. C. Sllbulata, MX. Pistillate spikelets 3 to 5, distant, on 

 included peduncles, loosely few-flowered, often staminate at sum- 

 mit ; perigynia subulate, finally reflexed, about 3 times as long as 

 the lanceolate acute scale.

 SUBULATE CAREX. 



Culms usually about 1 foot high (sometimes 2 or 3 feet, and then very slender, 

 and flaccid), smooth. Leaves flat, much shorter than the culm. Stam. spikelet 

 about % an inch long, terminal, on a short peduncle. Pistillate spikelets usually 

 4, 2- or 3- to 6- or 8-flowered, the perigynia half an inch long, the upper spikelet 

 eubsessile at the foot of the staminate one, with a lanceolate, awned, scabrous 

 bract at base, as long as the spikelet, the others lateral, on more or less exserted 

 peduncles. Beaks of the perigynia bicuspidate, with the slender points abruptly 

 reflexed, or barbed. 

 Hab. Swamps, among the slaty hills : rare. Fl. June. Fr. July. 



36. C. I ii pill ilia, Muhl. Pistillate spikelets 2 to 5, ovoid-oblong, 

 the upper ones approximated, on short peduncles, the lower 

 ones on exserted peduncles ; perigynia ovoid, much inflated at base, 

 acuminate, about 3 times as long as the lance-ovate acuminate 

 scale. 



HOP-LIKE CAREX.
