Treatment appears in FNA Volume 23. Treatment on page 444. Mentioned on page 445.

Plants densely cespitose, from short rhizomes. Culms erect or ascending, 7–27 cm × 0.4–0.7 mm; vegetative shoots taller than culms, (1.4–) 1.7–3.7 (–4.9) times as tall as tallest flowering culm; blades of vegetative shoots 1–3.5 times wider than bract blades. Leaves: basal sheaths white to light-brown; nonbasal sheaths 2.1–10.6 mm; blades erect, drooping or recurved, dark green, 0.4–52 cm × 1.6–6.1 mm, usually exceeding culms. Inflorescences: spikes (3–) 4 per culm, scattered; peduncles of proximal pistillate spikes drooping, to 9.1 cm; bracts dark green, 10–28 cm × 1.8–5.9 mm, well developed, blade of distal lateral spike (12–) 17–51 times as long as wide. Pistillate spikes: the proximal usually, usually basal, the distal sessile to very short-pedunculate, often hidden in foliage, 5.3–17 × 2.8–4.1 mm. Staminate spike sessile or nearly so, (8.3–) 9.6–16 (–21.1) × 0.6–1.3 mm, often hidden by distal bract and/or pistillate spikes. Pistillate scales 1.3–2.2 × 1.4–2.1 mm, midribs green, margins hyaline, apex acute, proximal scales of lateral spikes subtending perigynia. Staminate scales (2.6–) 2.8–3.5 (–3.8) × 1.1–1.7 mm, midribs green, margins hyaline, apex obtuse. Anthers 1.2–1.8 mm. Perigynia 4–8 (–9) per spike, distichously overlapping, finely veined, obovoid, 2.9–3.8 × 1.5–2.1 mm; beak tapering. Achenes ellipsoid, 2.2–2.9 × 1.4–1.8 mm, sides flat at maturity, filling perigynia. Style tapering from swelling just beyond attachment to achene, bent, ascending through entire orifice.
