KEPOHT OF THK STATE BOTANIST. 83 



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

 white scale; achenium exactly elliptical, stipitate, apiculate. 



Fields and woods. Very common. June, July. 



The species is distinguished by its long flexuous fertile spikes 

 and its spindle-shaped perigynia. 



Yar. strictior Builey. 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. 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, 1"-1^" wide, rough, bright green; staminate spike 

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

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

 1'-1t]-' 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. Eare. 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 Wald. 

 Stoloniferous ; 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^"-2" 

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

 staminate spike clavate, usually acutish at each end, 6"-9" long, on 

 a stiff stalk i'-l' in length, bright brown ; pistillate spikes 2-4, 

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

 apex or base, i'-l' long, 2" wide, the upper 2 or 3 aggregated on
