The stems are stiff, strong, with convex sides, sharply rough, down to 10 mm in diameter, 40-120 cm high [2] , surrounded by dark brown, wide, up to 10 mm wide, somewhat glossy, scaly-like sheaths.
The leaves are stiff, braid-like, flat or somewhat folded, 3-5 (10) [2] mm wide, equal to the stem.

The coverts are ovoid, sharp, equal to sacs, from brown to pale brown, with wide white-membranous edges, which makes the whole panicle whitish. The sacs are ovoid, unequally biconvex, 3–3.5 (4.5 [2] ) mm long, in front strongly convexly convex, with a widely rounded base, from the base with jagged and slightly curved back edges, thick-skinned, without veins or with few obscure veins at the very base, with elongated, directly truncated, serrated, only at the top slit-like split, winged (from the middle of the sac) nose, covered with very short, dense or scattered pressed hairs at the back. Covering leaves are scaly.
