C. Spikes several [rarely solitary), all of them androgynous. Stigmas 3. 



* Staminatc at the summit. 



30. Carex pedunculata, Muhl. Long-stalked Sedge. 



Spikes about 4, on long peduncles, very remote, staminatc above, erect ; perigynia obovate- 

 triquetrous, entire, about the length of the cuspidate scale. — Muhl. in Willd. sp. 4. p. 222 ; 

 Schlc. Car. t. Ggg. /. 131 ; Muhl. gram. p. 232 ; Dew. Car. I. c. 9. p. 259 ; Schwein. $ 

 Torr. Car. I. c. p. 309 ; Kunih, ernim. 2. p. 48. 



Culms cespitose, 4-8 inches high, slender, triquetrous, rough downward. Leaves pale 

 green, lj line wide, rather rigid, with a triangular point. Spikes usually 4 on one culm, few- 

 flowered ; the lower ones nearly radical ; all of them on slender peduncles : uppermost with 

 a larger sterile portion than the others. Sterile scales often dark brown, ovaie-lanceolate, 

 rigidly cuspidate. Fertile scales broader, and with a longer cusp. Perigynium with a long 

 attenuated base, smooth, membranaceous, nerveless, entire and somewhat recurved at the 

 orifice. Achenium triquetrous. Style continuous. 



Sides of rocky hills, and in dry woods : rare. Fl. April. Fr. May. 



** Staminatc at the base. 



31. Carex squarrosa, Linn. Squarrose-headed Sedge. 



Spikes 1-3, oblong or cylindrical-oblong, very thick ; perigynia inflated, with a long 

 straight beak, numerous, horizontal, squarrose, smooth, 2-toothed at the summit, longer than 

 the lanceolate glume. — Linn. sp. 2. p. 973 ; Willd. sp. 4. p. 215 ; Dew. Car. I. c. 8. p. 270.

Culm 1 J - 2 feet high, triquetrous, leafy, rough. Leaves about 2\ lines wide, longer than 

 the culrn. Spikes commonly solitary, but often 2 or 3, very rarely more, 1 - 2 inches long 

 and nearly three fourths of an inch in diameter, obtuse at each end. Sterile flowers at the base, 

 closely imbricated, and giving the upper part of the peduncle a clavate appearance. Scales 

 lanceolate, acute ; the fertile ones almost concealed by the crowded flowers. Perigynia tur- 

 binate and inflated below, with several strong nerves ; the upper ones nearly erect, middle 

 ones horizontal, and the lowest somewhat reflexed ; the long slender abrupt beaks giving the 

 spike a squarrose appearance. Achenium oblong, triangular, puncticulate-striate, crowned 

 with the long stout continuous style, which is often recurved within the perigynium. 



Bog meadows : frequent about New-York, but rare in the interior of the State. Fl. May. 

 Fr. June. A remarkable species, which is recognized at once by its large thick squarrose 

 spikes.
