CYPERACEtE. 



Carex. 



Fr. Early in August. Although very near C. Pennsylvania, it seems to be pretty constantly 

 distinct. 



64. Carex filiformis, Linn. Slender-leaved Sedge. 



Sterile spikes mostly 2 ; fertile 2, ovoid-oblong, nearly sessile, distant, erect ; perigynium 

 elliptical, with a short beak, densely woolly, bifid at the apex, about as long as the ovate- 

 lanceolate somewhat awned scale ; leaves involute. — Linn. sp. 2. p. ... ; Schk. Car. t. K.

 Kunth, enum. 2. p. 485. 



Culm 2-3 feet high, obtusely triangular, nearly smooth, rigid. Leaves principally radical, 

 forming a tuft, about as tall as the culm, channelled or involute, ending in a long filiform point. 

 Upper sterile spike elongated and pedunculate ; the lower one much shorter, and sessile : 

 scales oblong-lanceolate, acute, light brown with a green keel. Fertile spikes sometimes 

 solitary, but usually 2, an inch or 2 inches distant from each other, varying from half an inch 

 to 2 inches in length, densely fruited ; the lower one often staminate at the summit. Scales 

 acute, with a short rough awn or cusp, rather dark brown, with a green keel. Perigynia 

 nearly two lines long, coriaceous, moderately 2- toothed ; the teeth somewhat diverging. 

 Achenium obovoid-triquetrous, acute at the base. Style stout, somewhat articulated near the 

 base. 



Bog meadows. Fl. May. Fr. June. Highlands of Putnam county, and in the western 

 part of the State. 



65. Carex lanuginosa, Michx. Woolly -fruited Sedge. 



Sterile spikes 2 ; fertile usually 2, ovoid-cylindrical, remote, erect, nearly sessile ; perigynia 

 ovoid, somewhat triangular, densely hairy, with a short bicuspidate beak, about the length of 

 the oblong cuspidate or mucronate scale ; leaves flat. — Michx. fl. 2. p. 175 ; Torr. Cyp.

Culm about 2 feet high, somewhat terete below, triangular above, a little rough. Leaves 

 2-3 lines wide, rough on the margin. Sterile spikes commonly 2, but sometimes single or 

 three together ; the uppermost cylindrical and pedunculate, the others sessile. Scales oblong- 

 lanceolate, brown, acute, obtuse or mucronate. Fertile spikes sometimes 3 ; the lowest one 

 on a short peduncle, about an inch long ; one or more of the others occasionally pistilliferous 

 at the base. Scale tapering to a slender acute point, and commonly mucronate. Perigynium 

 coriaceous, 2 lines long, clothed with a dense roughish pubescence, brownish when mature, 

 obscurely nerved. Achenium triquetrous, obtuse ; the style indistinctly articulated near the 

 base. 



Wet meadows and borders of lakes : rather rare. Fl. May - June. Very near the pre- 

 ceding species.
