Rootstock very densely cajspitose, without elongate stolons. Stem 

 erect, rather slender, rigid, triquetrous, rough towards the apex. Leaves 

 as long as or a little shorter than the stem, erect, rather firm, linear, 

 flat, rough on the margins, dull green, more or less glaucous ; sheaths 

 at length split and li'.amentous at the margins, the lowest ones on 

 the flowering stem without laminae. Male spike 1 (more rarely 2), 

 cylindrical. Female spikes 1 to 3, subapproximate, sessile or sub- 

 sessile, erect, oblong- or fusiform-cyhndrical, with the fruits imbricated 

 in 8 longitudinal rows. Lowest bract foliaceous, not sheathing, not 

 reaching the apex of the male spike, with 2 rather long narrow adnate 

 pale reddish scarious auricles at the base, resembling a split sheath a 

 little longer than the "sridth of the bract. Glumes of the female 

 flowers elliptical-lanceolate, obtuse or acute, reddish-black, usually 

 with a green midrib and concolorous or very rarely pale scarious
