phyllopodic, with dead leaf remains at base, 5–35 cm. |
red- or purple-brown at base. |
blades 1–2.5 mm wide, margins sometimes involute, scabrid at tip. |
basal sheaths fibrous; sheath fronts membranous, spotted or streaked with red or pale brown; blades V-shaped in cross section when young, sometimes involute, glabrous. |
proximal bracts 0.5-2 cm, much shorter than inflorescences; lateral spikes 6–15 × 3.5–5 mm, with 2–10 perigynia; terminal spikes 6–20 × 1–2.5 mm. |
racemose, with 2–5 spikes; proximal bracts sheathless or sheath less than 4 cm; lateral spikes pistillate, androgynous, or gynecandrous, pedunculate, prophyllate; terminal spikes staminate, gynecandrous. |
2.5–4.5 × 1.6–2 mm, apex rounded; beak absent. |
ascending, inflated, (3–)5–7-veined on abaxial face, veinless or 3–7-veined on adaxial face, stipitate or sessile, broadly elliptic or ovate, rounded-trigonous in cross section, base tapering or rounded, apex tapering or rounded to beak or beakless, minutely papillose; beak 0–0.5 mm, mouth entire or emarginate. |
|
trigonous, almost as large as bodies of perigynia; style deciduous or persistent portion protruding from perigynium mouth. |
scales circular-ovate, 3–4.8 × 2.2–3.4 mm, long as and wider than perigynia, apex obtuse, sometimes mucronate. |

Species 6 (6 in the flora). The species of Carex sect. Limosae can be readily recognized by the dense yellowish indumentum on the roots. If collected without the roots they can be confused with species of C. sect. Racemosae, sect. Scitae, and sect. Paniceae.
