Leaves overtopped by culm; blades ascending, filiform, 0.3–0.5 mm wide, margins deeply involute, then channeled, apex tri-gonous, setaceous. Inflorescences: spikelet clusters 1–2(–4), dense(–open), narrowly to broadly turbinate; branches capillary, variously elongate; leafy bracts setaceous, proximal exceeding clusters. Spikelets brownish, lance ellipsoid to fusiform, 2–2.5(–3) mm, apex acute; fertile scales broadly elliptic, 1.5 mm, apex narrowly rounded to broadly acute, apiculate, convex cupulate, midrib narrow, short excurrent or included.
