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

 white scale; achenium exactly elliptical, stipitate, apicalate. 



Fields and woods. Very common. June, July. 



The species is distinguished by its long flexuous fertile spikes 

 and its spindle-shaped perigynia. 



Var. strictior Bailey. 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. 



Yar. interjecta Bailey. Stems tall, erect ; pistillate spikes 

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

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

 rower 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, V'-IV wide, rough, bright green ; starn-inate spike 

 linear, V long or more, short-peduncled, often fertile at the apex; 

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

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

 filiform drooping peduncles l'-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, 2^''-3" or more in length, 

 gradually tapering into an empty sharply bidentate beak, twice 

 the length of the obtuse brown-margined scale. 



Wet places. Kare. June, July. Oneida and Otsego counties. 



The few flowered slightly flexuous fertile spikes and the large 

 perigynia are characteristic of this species, which approaches 

 C. debilis in appearance. 



98. Carex castanea Wahl. 

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

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

 in length, the radical half as long as the culm or more, l-J-"-2'' 

 broad, soft-hairy, conspicuously veined, glaucous or fulvous-green; 

 staminate spike clavate, usually acutish at each end, t>"-9" long, on 

 a stiff stalk i'-V in length, bright brown; pistillate spikes 2-1, 

 oblong, or cylindrical, densely flowered, sometimes sterile at the 

 apex or base, V-Y long, 2" wide, the upper 2 or 3 aggregated on
