Description Culms often spreading or declining, 3–30 cm × 0.5–1 mm. Leaves: apex of distal leaf sheath obtuse, tooth to 0.2(–0.5) mm. Spikelets ellipsoid to ovoid, 3–10 × 2–4 mm, apex blunt to subacute; floral scales 10–100+, 10 per mm of rachilla, colorless to pale brownish except for green midrib, 1.5–2 × 1 mm, midribs not keeled, apex rounded.
