--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>densely cespitose. <b>Culms</b> 14–110 cm. <b>Leaves</b>: sheaths adaxially white-hyaline, summits U-shaped to rounded, often prolonged to 3 mm beyond collar; distal ligules (1.5–)2–3.5 (–5) mm; blades 3–4(–5) per fertile culm, 8–25 cm × (2–)3–5 mm. <b>Inflorescences</b> dense, brown or gold, usually ± triangular, 1.6–3 cm × 12–20 mm; proximal internode 3–5.5 mm; 2d internode 1.5–5 mm; proximal bracts scalelike or bristlelike, shorter than inflorescences. <b>Spikes</b> 4–6(–10), densely aggregated or, sometimes, proximal 1 distant, narrowly to broadly ovoid, (8.5–)10–12 × 6–11 mm, base rounded to attenuate, apex truncate to acute. <b>Pistillate</b> scales gold or light red-brown, often with pale or green midstripe, ovate to lanceolate, (3.2–)3.9–4.8 mm, longer and narrower than perignyia, margin white, 0.1–0.5 mm wide, apex acuminate. <b>Perigynia</b> ascending to ascending-spreading, green and white, gold, or light brown, conspicuously (8–)10–17-veined abaxially, conspicuously (0–)4–12-veined adaxially, at least 3 adaxial veins longer than achene, usually ovate or broadly ovate, plano-convex, (3.8–)4.4–5.5(–6) × (1.4–)1.8–2.5 mm, 0.5–0.8 mm thick, margin flat, including wing (0.2–)0.3–0.4(–0.5) mm wide, ciliate-serrulate distally; beak gold to dark brown at tip, flat, ± ciliate-serrulate, abaxial suture inconspicuous or with conspicuous white margin, distance from beak tip to achene 2–2.8(–3.3) mm. <b>Achenes</b> elliptic to broadly ovate, 1.7–2.4 × 1.1–1.7 mm, 0.4–0.6 mm thick.</span><!--

|discussion=<p>While Carex multicostata and C. specifica are usually quite distinct, the perigynia of C. multicostata are sometimes lanceolate and strongly resemble those of C. specifica. The type specimen of C. multicostata has unusually elongate inflorescences resembling those of C. specifica, rather than ± short-triangular inflorescences usually present in C. multicostata.</p>
