HEPOBT OF THE STATE BOTAKIST. 83 



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

 white scale; acheniam exactly elliptical, stipitate, apiculate. 



Fields and woods. Very common. June, July. 



The species is distinguished by its long flexuous fertUe spikes 

 and its spindle-shaped perigynia. 



Var. strictior Bi'iley. 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 

 nearlj' erect, often compound at base, alternately flowered ; peri- 

 gynia shorter than in the tj'pe. 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, l"-li" wide, rough, bright green ; staminate spike 

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

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

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

 filiform drooping peduncles l'-(J' 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. Rare. June, July. Oneida and Otsego counties. 



The few flowered slighth^ flexuous fertile spikes and the large 

 perigynia are characteristic of this species, which approaches 

 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 W-V in length, bright brown ; pistillate spikes 2-i,
