 146. 1803. 



Closely resembles the preceding species, but has 

 weak spreading or reclining culms 2 f -\2 r long. 

 Leaves narrower, i" " wide, involute; spikes 2 or 

 3, gynaecandrous, oblong or subglobose, few or 

 several-flowered, 2\"-6" long, about ii" in diameter, 

 brown, subtended by very small scale-like bracts ; 

 perigynia lanceolate, if" long, i" wide, tapering at 

 apex into the beak, strongly several-nerved ; scales 

 ovate, obtusish, brown, with hyaline margins, ex- 

 ceeded by the perigynia ; achene filling perigynium ; 

 stigmas 2. 



Brackish soil along St. Lawrence, Quebec. Very local. 

 Also in northern Europe. Summer.

 or none ; spikes 2-5, subglobose, gynaecandrous, not long- 

 clavate at base, brown, 2"-^" long, 2"-$" wide, clus- 

 tered at the summit; perigynia 5-10, appressed-ascend- 

 ing, broadly ovate or ovate-elliptic, blunt-edged, faintly 

 several-nerved, ij" long, more than \" wide, tapering at 

 apex into the short sharp beak; scales ovate, brown with 

 broad hyaline margins, nearly as long as the perigynia; 

 achene filling perigynium ; stigmas 2.

Carex norvegica Willd. ; Schk. Riedgr. 50. 1801. 



Culms slender but stiff and erect, smooth, 6'-i6' 

 tall, from much elongated rootstocks, stoloniferous. 

 Leaves \\" wide or less, shorter than the culm, 

 glaucous ; bracts very short or wanting ; spikes 3-6, 

 gynaecandrous, brown, oblong or subglobose, the 

 upper close together, the lower separate, densely 

 many-flowered, 3 "-6" long, \\"-$' in diameter, the 

 uppermost conspicuously clavate at base; perigynia 

 ascending, ii"-i*" long, i" wide, thick, coriaceous, 

 broadly 'obovoid, blunt-edged, abruptly narrowed to a 

 stipitate base, brownish, finely many-nerved, abruptly 

 tipped with a very short smoothish beak; scales

 than the perigynia; achene filling perigynium; stig- 

 mas 2.

 ward. Also in Europe and Asia. Summer. 

 Carex pseudohelvola Kihlm., supposed to be a hybrid between this species and Carex cancscens
