BEPOET OF THE STATE BOTANIST. 65 



ovate, acute or cuspidate scale ; achenium 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 WaM. 



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

 sometimes roughish at the summit ; leaves slightly hispid on the 

 upper surface, smooth beneath, 14"-3" wide, the highest exceeding 

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

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

 length, the upper 2 usually contiguous, the upj^ermost sessile, the 

 others more or less distant on stiff, erect peduncles J'--l' long, 

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

 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 ; achenium 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 whi h 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-triquetrous, 

 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 Ilitchcockiana. 



68. Carex oligocarpa Schk. 

 Stems 6'-] 8' high, slender, erect or somewhat diffuse, rough on 

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

 about 1" wide, slightly rough on the veins beneath and margins ;
