ferred to this species. 



This very distinct plant is unlike anything else known from the 

 United States. It is probably most closely related to species 

 Hke Carex htziilaef alia W. Boott, but the small few-flowered spikes 

 and small perigynia quickly distinguish it.

Clumps large, with slender elongated rootstocks, the culms 4—8 

 dm. high, exceeding the leaves, smooth or nearly so on the angles, 

 somewhat fibrillose at base. Leaves with well-developed blades 

 three to twelve to a fertile culm, the lower clustered, the upper 

 widely separate and with conspicuous elongated sheaths, the 

 blades flat, 4-12 mm, wide, usually 1-4 dm. long, much rough- 

 ened towards apex; staminate spike one, short-peduncled, 2-3 

 cm. long, 2.5 mm, wide, the scales oblanceolate or oblong-obovate, 

 obtuse, or the lower acute or acuminate, whitish-hyaline with green 

 center; pistillate spikes one to three, widely separate, erect, the 

 lower on long rough peduncles, the upper short-peduncled or 

 nearly sessile, the spikes suborbicular, 1.5-2.5 cm. long, 2-3 cm. 

 wide, conspicuously staminate at apex, and with 8-20 widely 

 spreading perigynia below, rather loosely arranged in few ranks ; 

 bracts leaf-like with conspicuous elongated sheaths, exceeding in- 

 florescence ; scales ovate, varying from acute to cuspidate, whitish- 

 hyaline with strongly nerved green center, somewhat narrower and
