408 CYPERACEiE. Carex. 



broadly ovate, generally mucronate or acute, but sometimes nearly obtuse, pale tawny wilh a 

 green keel. Perigynium 1^ line long, distinctly striate, gibbous, wilh a longish curved point, 

 acute at the base. Achenium obovoid, triquetrous. Style short, somewhat articulated. 



Woods and grassy places : very common. Fl. May. Fr. June. The narrow-leaved 

 state of the plant usually grows in moist places. 



82. Carex blanda, Dew. Pale Smooth Sedge. 



Sterile spike solitary, pedunculate, triquetrous ; fertile spikes mostly 3, oblong-cylindrical, 

 rather loosely flowered, the uppermost one nearly sessile, the lowest on a long peduncle ; 

 perigynia obovoid, somewhat triangular, nerved, smooth, recurved and entire at the point, 

 scarcely longer than the ovate mucronate scale. — Deiv. Car. I. c. 10. p. 45, and 11. t. K.

 p. 248, not of Schk. 



Culm 8-12 inches high, leafy, triquetrous, roughish on the angles. Leaves 2-3 lines 

 wide, pale green and somewhat glaucous. Sterile spike half an inch to an inch or more in 

 length ; the peduncle sometimes elongated, but usually short : scales oblong, rather obtuse, 

 pale brown. Fertile spikes 2-4, about three fourths of an inch long ; the two upper ones 

 often approximated, the lowest remote : peduncles 2-edged. Scales tawny with a green keel : 

 lower ones cuspidate, nearly as long as the perigynium ; the upper ones shorter. Perigynium 



1 i line long, obtuse, with a short recurved point, yellowish when mature. Achenium obovoid- 

 Iriquetrous. Style very short, somewhat articulated. 



Woods, usually in dry soil : common. Fl. May. Fr. June. This plant is difficult to 

 distinguish from certain forms of C. anceps. If it is a good species, it should take the name 

 of C. striatula, that being the older name. 



83. Carex Crawei, Dew. mss. Crawe's Sedge. 

 Sterile spike single, oblong ; fertile 2-3, oblong-cylindrical, distant, erect, rather closely 



flowered, the lowest on a longish peduncle ; perigynium ovoid-oblong, pointed with a short 

 beak, slightly nerved, entire at the orifice, twice as long as the ovate scale. — Dew. in lit. 

 Whole plant light green. Culm 4-8 inches high, erect, triquetrous, leafy. Leaves about 



2 lines wide, smooth, as long as the culm. Sterile spike pedunculate, about three fourths of 

 an inch long ; the scales lanceolate, rather obtuse, light brown, scarious on the margin, with a 

 green keel. Fertile spikes 6-8 lines long ; the lowest on a short exserted peduncle. Scales

 inflated, obtuse, with a very short beak which is a little recurved. Achenium oblong, trique- 

 trous, acuminate. Style continuous.
