Inflorescences: spikes (2–)3–(–4) per culm, scattered; peduncle of pistillate spike usually erect or spreading, rarely drooping, exserted 0–11.5 cm; bracts sheaths green, occasionally with purple traces, from middle and proximal portions of culms with blades 2.1–9.2 cm × 1–4 mm. Pistillate spikes proximal sometimes basal, 7–18 × 4–7 mm. Staminate spike 1, pedunculate, oblanceolate to linear, 8–20 × 2–3.5 mm. Pistillate scales keeled, 3.5–4.2 × 1.8–2.2 mm, midribs green, margins hyaline, occasionally purple tinged outward, apex cuspidate to acute.
