--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>densely cespitose. <b>Culms</b> dark maroon at base; flowering stems 25–80 cm, much longer than leaves at maturity, 1–1.8 mm thick, glabrous but scabrous on angles, especially within inflorescence. <b>Leaves</b>: basal sheaths maroon, bladeless, glabrous on back; others grading from maroon to green on back, brown-hyaline and usually red dotted on front, glabrous or often pubescent near apex; blades flat, 2.5–5.5 mm wide, usually less than 4 mm wide, glabrous or sparingly rough-hispidulous on 1 or both surfaces, margins scabrous, especially distally. <b>Inflorescences</b>: peduncles of proximal spikes 0–65 mm and finely scabrous; peduncle of terminal spike 0–12 mm, scabrous; proximal bracts equaling or exceeding inflorescences; sheaths 8–40 mm; blades 1–4 mm wide. <b>Lateral</b> spikes 3–5, 1 per node, well separated, erect or arching at maturity, pistillate with 20–45 perigynia attached 0.5–2 mm apart, rarely the distal staminate, linear to narrowly cylindric, 10–60 × 2.5–6 mm. <b>Terminal</b> spike staminate, rarely with a few perigynia, sessile or pedunculate, 18–38 × 1.2–4 mm. <b>Pistillate</b> scales with green midrib and broad pale hyaline margins suffused with reddish or golden brown, broadly ovate, shorter than mature perigynia, apex acute to rounded, sometimes cuspidate, margins ciliate distally, otherwise glabrous. <b>Perigynia</b> green to golden green, usually blotched or dotted with dark red, 2-ribbed and finely 12–15-veined, veins more obvious on abaxial side, loosely enveloping achene, oblong-lanceolate, 2.7–5 × 0.8–1.8 mm, membranous, base acute, apex tapering to beak, sparsely pubescent toward apex; beak minutely bidentate, 0.3–1 mm, ciliate between apical teeth. <b>Achenes</b> sessile, 1.6–2.5 × 0.9–1.5 mm. <b>2n</b> = 56, 58, 60.</span><!--

|discussion=<p>Occasional sterile hybrids between <i>Carex mendocinensis</i> and <i>C. gynodynama</i> are found where the species grow together. Specimens from the northern part of the range tend to have pubescent leaf sheaths and perigynia that taper more gradually to the beak.</p>
