Characteristics

Rhizomes horizontal, threadlike, 0.3–0.8 mm in diam. Culms arising singly or 2–3 together, ± terete, scarcely furrowed, 2–30 cm; lateral sterile shoots often with prostrate or curved base. Leaf blades filiform, 2–15 cm × 0.3–0.7 mm. Inflorescence androgynous (14%), wholly staminate (12%), or wholly pistillate (74%); staminate spike 8–16 mm; pistillate spike ± densely 4–15(–18)-flowered, transversely broadly oblong to ovoid-oblong or oblong, 5–14 × 4–8 mm. Pistillate scales uniformly light to dark brown or with pale or green midvein, margins scarious, narrow to broad. Perigynia becoming divergent or slightly deflexed, yellow, olive, or at maturity chestnut-brown, obscurely to evidently 17–20-striate (marginal ribs seldom prominent), oblong-ovoid, biconvex, 2.9–3.4 × 1.2–1.7 mm; beak 0.5 mm, margins glabrous or sparsely scabrid. Achenes 1.5–1.7 × 1–1.2 mm. 2n = 46, 48.
More
Rhizome slender, creeping. Culms loosely tufted, 20-30 cm tall, smooth, leafy on lower 1/4. Basal leaf sheaths rusty brown, eventually pale brown, split into fibers. Blades shorter than culm, ca. 0.5 mm wide, smooth. Plants dioecious, male plant not seen; inflorescence 1-spiked, terminal; female spike brown, narrowly cylindric, 1.5-1.8 × ca. 0.2 cm. Female glumes rusty brown, broadly ovate, apex acute. Utricles nearly equaling to slightly longer than glume (ripe specimens not seen), 2-2.5 mm, slenderly veined on both surfaces, apex gradually attenuate into a short beak, orifice minutely 2-toothed; stigmas 2.
