--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>densely to loosely cespitose; rhizomes short, no more than 10 cm. <b>Culms</b> trigonous in cross section, 25–100 cm, scabrous distally. <b>Leaves</b>: basal sheaths pale brown (rarely faintly red tinged); ligules usually much longer than wide; blades mid to dark green, flat to W-shaped, 4–13 mm wide, glabrous. <b>Inflorescences</b> 4–15 cm; proximal bract 12–55 cm, greatly exceeding inflorescence; proximal 2–5 spikes pistillate, erect or the proximal pendent, cylindric, 9–12 mm thick; terminal 1 spike staminate or, rarely, gynaecandrous, androgynous, or mixed. <b>Pistillate</b> scales lanceolate-acuminate, 2.5–8.6 × 0.3–0.6 mm, the distal shorter and the proximal longer than perigynia, margins ciliate, apex scabrous-awned. <b>Staminate</b> scales scabrous-awned, sometimes also ciliate-margined. <b>Perigynia</b> spreading to reflexed at maturity, strongly 12–20-veined, veins usually separated by less than 2 times their width, confluent at or proximal to mid beak (except for 2 prominent lateral), tightly investing achene, narrowly elliptic to lanceolate, 3.4–6.1 × 1–1.7 mm, leathery, apex gradually tapered; beak poorly defined, 1.2–2.2 mm, strongly bidentate, teeth straight or slightly out-curved, 0.7–1.2(–1.4) mm. <b>Stigmas</b> 3. <b>Achenes</b> pale brown, trigonous, smooth. <b>2n</b> = 66.</span><!--

|discussion=<p><i>Carex pseudocyperus</i> is a smaller and more slender plant than <i>C. comosa</i>, but otherwise very similar. The two species often grow together where their ranges overlap and rarely produce sterile hybrids. Hybrids with <i>C. hystericina</i> are more frequent, and resemble C. pseudo- cyperus except for their sterility, the slightly more inflated and less reflexed perigynia, and the substantial red tinging on the basal sheaths.</p>
