Characteristics

Plants cespitose, long-creeping rhizomatous. Culms 25–35 cm, smooth. Leaves 2–3 mm wide, often circinate. Inflorescences: proximal bracts shorter than or exceeding inflorescences; spikes globose or elongate, 6–17 × 6–10 mm; proximal spikes sometimes erect, separate, short-pedunculate; distal spikes contiguous, overlapping, or erect, sessile or short-pendunculate, forming dense terminal cluster; lateral 1–2(–4) spikes pistillate; terminal spike gynecandrous. Pistillate scales light to dark brown or chestnut, distal margins broadly hyaline, lanceolate, equaling or, more commonly, exceeding and narrower than perigynia, midvein lighter colored than body, conspicuous, often raised, prominent, apex acute or mucronate. Perigynia ascending, light brown, strongly veined, broadly elliptic, 4–5 × 2–3 mm, apex abruptly beaked, smooth or distally papillose; beak 0.6–0.8 mm, deeply, sharply bidentate, smooth or papillose. Achenes nearly filling body of perigynia.
More
Rhizome creeping, with stolons. Culms 15-40 cm tall, smooth, clothed at base with reddish brown bladeless and blade-bearing sheaths. Leaves shorter than culm, blades linear, 2-3.5 mm wide, stiff, weakly involute. Lower involucral bracts shorter than inflorescence. Spikes 2-5, upper spikes approximate, lower 1 or 2 distant; terminal spike gynaecandrous, sometimes male, clavate, 2-2.5 × 0.8-1 cm; remaining spikes female, ovate to ovate-oblong, 1.5-2 × 0.8-1 cm; peduncles 1-2 cm. Female glumes ferruginous with a pale midrib, ovate, margins white hyaline, apex acute. Utricles yellow-green, broader than but as long as or shorter than glume, ovate, trigonous, 4-5(-6) mm, smooth, 3-5-veined, base broadly cuneate, stipitate, apex abruptly contracted into a smooth, deeply 2-lobed beak. Fr. Jun-Jul.
