hyaline bifid beak, twice the length of the obtuse or acutish 

 ■\thite scale; acheniam exactly elliptical, stipitate, apiculate. 



Fields and woods. Yery common, June, July. 



The species is distinguished by its long flexuous fertile spikes 



1(1 its spindle-shaped perig^^nia. 



Var. strictior B dleu. Stems taller and mostly erect ; leaves 

 firmer, 2" wide, spikes stiff and erect or erect-spreading ; peri- 

 gynia deep green, a little longer than the scale. 



Var. interjecta Bailey. IStems tall, erect ; pistillate spikes 

 nearly erect, often-cornpound at base, alternately flowered ; peri- 

 vnia shorter than in the type. Differs from the last in its nar- 

 Aver leaves and more loosely flowered spikes. 



97. Carex glabra Boott. 



Stems l°-2° high, slender, erect or somewhat spreading, 

 smooth ; basal bracts dark purple ; leaves about the length of the 

 culm or less, 1"-1-J-" wide, rough, bright green ; staminate spike 

 linear, 1' long or more, short-pedancled, often fertile at the apex; 

 pistillate spikes 3-4, cylindrical, flexuous, subloosely flowered, 

 l'-l|' long, the upper 2 approximate, the lowest remote, all on 

 filiform drooping peduncles 1-6' long, or the uppermost short- 

 stalked and suberect ; bracts leafy or the upper ones filiform, 

 sheathing, usually exceeding the culm; perigynia narrowly 

 oblong-elliptical or lanceolate, nerved, 2y'-3" or more in length, 

 gradually tapering into an empty sharply bidentatt- Ivak, twice 

 the leno;th of the obtuse brown-margined scale. 



Wet places. Hare. June, July. Onei<la and Oti^ego counties. 



The few flowered sliglitly flexuous fertile spikes and the large 

 perigynia are characteristic of this species, which approaches 

 C. debilis in appearance.

 Stol miferous ; stems l°-2'' high, erect, acutely angled, lightly 

 pubescent, basal bracts dull brown, pubescent; stem leaves 1-3' 

 in length, the radical half as long as the culm or more, ir-2*
