--><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, usually longer than leaves at maturity, 1–2 mm thick, glabous to pubescent. <b>Leaves</b>: basal sheaths maroon, bladeless, pubescent, sometimes glabrous, others grading from maroon to green on back, light brown-hyaline on front, dotted or streaked with dark red, pubescent distally; blades flat, 3–7 mm wide, pilose, especially abaxially, sparsely so distally, margins ciliate. <b>Inflorescences</b>: peduncles of lateral spikes slender, 5–20 mm, shorter than spikes, pubescent; peduncle of terminal spikes 5–40 mm, minutely scabrous; proximal bracts nearly equaling but usually not exceeding inflorescences; sheaths 15–25 mm; blades 1.5–3 mm wide. <b>Lateral</b> spikes 2–4, 1 per node, distal 2 usually overlapping terminal spike, others well separated, nodding or drooping at maturity, pistillate with 20–45 perigynia attached 1.5 mm apart, narrowly cylindric, 15–45 × 3–4.5 mm. <b>Terminal</b> spike gynecandrous, 15–45 × 2–4.5 mm. <b>Pistillate</b> scales hyaline with broad green, red dotted midrib, elliptic-ovate, shorter than mature perigynia, apex acute to aristate or awned, awn less than 1 mm, ciliate. <b>Perigynia</b> green to dark olive-green, copiously red dotted, 2-ribbed with 6–10 almost equally prominent veins, loosely enveloping achenes, ellipsoid-ovoid, 3.5–5 × 1.7–2 mm, membranous, base acute or with short stipe, apex gradually tapered to beak, glabrous or less often pubescent; beak minutely bidentate, 0.4–0.7 mm. <b>Achenes</b> distinctly stipitate, 1.7–2.5 × 1–1.5 mm, stipe to 0.7 mm.</span><!--

|discussion=<p>Plants with glabrous leaves and sheaths are occasionally found and have been treated as <i>Carex oxylepis</i> forma glabra Kükenthal; plants with perigynia pubescent, in addition to normally pilose leaves and sheaths, have been treated as <i>C. oxylepis</i> <i></i></i>var.<i><i> pubescens</i>. Taxonomic recognition is not warranted in either case because the traits vary within populations and are not correlated with other structural differences.</p>
