CYPERACEyE. 



Carex. 



73. Carex Torreyi, Tuckerm. Torreijs Sedge. 



Sterile spike solitary, oblong, on a short peduncle ; fertile 2-3, erect, the peduncles in- 

 cluded ; perigynia obovoid, obtuse, somewhat triangular, nerved, smooth, mucronate, with a 

 short entire orifice, one third longer than the acute mucronate scale ; culm, leaves and bracts 

 pubescent. — Tuckerm. enum. Car. p. 21 ; Deio. Car. I. c. 49. p. 43. t. Ee. /. 109. 



Culm 12-18 inches high, triquetrous, rough on the angles. Sterile spike half an inch 

 long, oblique ; the scales ovate, mucronate, light brown, slightly pubescent on the margin. 

 Fertile spikes few-flowered, half an inch in length ; the short bracteal leaf at the base of the 

 lower one strongly pubescent, and ciliolate on the margin. Scales ovate, a little pubescent on 

 the prominent keel. Perigynium about a line and a half long, many-nerved, very obtuse, with 

 the entire orifice somewhat produced. Achenium filling the cavity of the perigynium, short- 

 obovoid, triquetrous. Style very short. 



State of New-York (Mr. Tuckerman). 



74. Carex striata, Michx. Striated Sedge. 



Sterile spikes 1 - 2 ; fertile usually solitary, or rarely two and distant, oblong-cylindrical, 

 pedunculate, erect, rather loosely flowered ; perigynium oblong-ovoid, somewhat triangular, 

 nerved, puncticulate-scabrous ; the beak conical-oblique, entire at the orifice, a little longer 

 than the ovate rather acute scale. — Michx. ft. 2. p. 174 ; Tuckerm. Car. I. c. C. polymorpha, 

 Muld. gram. p. 239 (in part) ; Torr. Cyp. p. 413 (in pari). C. Halseyana, Dew. Car. I.e. 

 11. p. 313, and 19. t. N. /. 43 ; Beck, hot. p. 441 ; Kunlh, enum. 2. p. 518. 



Culm 12-18 inches high, triquetrous, slightly rough. Leaves about 3 lines wide, dark 

 green. Slerile spikes 1-4, the upper one about an inch in length, the others shorter ; the 

 scales oblong, obtuse, pale reddish brown with a pale border. Fertile spikes about an inch 

 long, rather loosely flowered. Scales sometimes rather obtuse, purplish brown, with a pale 

 border and green keel. Perigynia 2i lines long, slightly inflated, few-nerved, roughened with 

 little elevated dots ; the orifice membranaceous and oblique. Achenium oblong, triquetrous, 

 very acute, rough like the perigynium. Style continuous. 



Swamps, western counties : rare. Fl. May. Fr. June. My much valued friend Dr. 

 Boolt has convinced me that two distinct species have been confounded by Prof. Dewey and 

 myself (as was done also by Muhlenberg), under the name of C. Halseyana or polymorpha. 

 The northern plant is clearly the C. striata of Michaux, whose name is here adopted. 



75. Carex granularis, Muld. Granular -spiked Sedge. 



Sterile spike solitary, nearly sessile ; fertile mostly 3, oblong-cylindrical, remote, densely 

 flowered, the two lower on erect exserted peduncles ; perigynia globose-ovoid, many-nerved ; 

 the beak very short, entire and somewhat recurved. — Muhl. in Willd. sp. 4. p. 279 ; Schk. 

 Car. t. Vvv. /. 169 ; Dew. Car. I. c. 7. p. 272, and 11. p. 156 ; Schwein. # Torr. Car. 

 I. c. p. 349 ; Kunth, enum. 2. p. 457. 



Culm usually about a foot high, erect or somewhat decumbent, slender, triquetrous, smooth.
