Stem

Clumped growth, with basal sheath color light brown, and length about 20-80 cm.

Leaves

Leaves shorter than the stem, have glabrous surfaces, width about 3-5 mm.

Inflorescence

The number of spikes two or more. Spike shapes all same (no distinct differentiation between sexual characteristics), with some spikes bisexual. Spike sexuality androgynous (staminate flowers above the pistillate in the same spike). Entire inflorescence length about 5-8 cm, spikes arranged densely. Terminal spike sexuality androgynous. Lateral spike sexuality androgynous, and erect to ascend. Terminal spike length about 5-8 cm (by misinterpretation). Number of spikes per node one (one spike in one bract).

Bract

Lowermost bract shape leaf-like or thread-like.

Glume

Staminate glume awn absent. Pistillate glume awn short (awn less than one-third of the total length). Pistillate glume color whitish green to light brown.

Perigynium

Transverse section lenticular to biconvex. Perigynium shape ovate-lanceolate (the broadest part near the base), and densely flowered. Perigynium glabrous (?) or hairy or pubescent (?). Beak short (beak less than one-third of the total length) or long (beak more than one-third of the total length), thick (the beak is not distinguished from the perigynium , and the starting point of the beak is more than one-third of the widest part of the perigynium), with bidentate to bifid mouth. Length 3-4 mm.

Achene

Appendage absent, no constrictions.
