KEPOBT OF THB STATE BOTA'nST 163 



ovate, acute or cuspidate scale ; acheniurn obovate ; style even 

 (not tumid), curved or abruptly bent at the base. 



Thin woods and moist places. Rare. June, July. Cayuga 

 and Dutchess counties. 



This species may be separated from C. grisea, which it resem- 

 bles, by its shorter stems and leaves, its more cylindrical spikes, 

 and shorter perigynia, and by its curved styles. 



67. Carex grisea Wahl. 



Stems l°-2^° high, firm, usually somewhat robust, smooth, or 

 sometimes roughish at the summit ; leaves slightly hispid on the 

 upper surface, smooth beneath, l|"-3" wide, the highest exceeding 

 the culm, pale green ; staminate spike 3"-9" long, sessile ; pistillate 

 spikes 2-4, oblong, thick, loosely or subloosely flowered, ^'--1' in 

 length, the upper 2 usually contiguous, the uppermost sessile, the 

 others more or less distant on stiff, erect peduncles ^'--1' long, 

 light green or fading to tawny; bracts leafy, sheathiag, ereot- 

 spreading, or the upper divergent, much longer than the culm ; 

 perigynia oblong, obtuse, turgid, finely nerved, about the length 

 of the ovate, cuspidate or rough-awned scale ; acheniurn obovate, 

 sometimes apiculate, with a straight, tumid or bulbous-thickened 

 style. 



Moist ground and grassy places. Common. June. 



This species frequently forms tufts. Its straight, tumid or 

 bulbous-thickened style articulates at or slightly above its base. 

 A slender narrow-leaved form occurs whijh closely approaches, 

 and which perhaps is referable to Var. angustifolia Boott. 



Leaves and bracts alike, sheathing, conspicuously thin, the 

 latter exceeding the culm ; perigynia obovoid or ovate-tric|uetrous, 

 finely striate or nerved, distinctly beaked, shorter than the tri- 

 nerved, pointed or rough-awned scale. 



Spikes 3-8 flowered, sheaths smooth oligocarpa. 



Spikes 3-10 flowered, sheaths pubescent Ilitchcookiana. 



68. Carex oligocarpa .V/i^-. 

 Stems 6'--18' high, slender, erect or somewhat diffuse, rough on 

 the upper portion ; leaves short, or sometimes equaling the culm, 

 about I" wide, slightly rough on the veins beneath and margins ;
