--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>densely cespitose. <b>Culms</b> 30–100 cm; vegetative culms with numerous leaves spaced evenly along distal 1/2. <b>Leaves</b>: sheaths adaxially green-veined nearly to collar, with V-shaped hyaline band extending 4–20 mm proximal to collar; somewhat loose, expanded near summit, ± wing-angled, adaxially firm, summits truncate to U-shaped, prolonged beyond collar; distal ligules 4–10 mm; blades 4–6 per fertile culm, 13–40 cm × 3–7.5 mm. <b>Inflorescences</b> dense or proximally open, brown, 2–4(–4.5) cm × 8–15 mm; proximal internode 2–6 mm; 2d internode 2–4 mm; proximal bracts scalelike with bristle tip to 1(–8) cm. <b>Spikes</b> 6–15, usually widely spaced, globose, 4–8 × 4–8 mm, base rounded to tapered, apex rounded. <b>Pistillate</b> scales white-hyaline or pale brown with green to brown midstripe not reaching tip, lanceolate, 1.6–2.3 mm, 1/2 length of and narrower than perigynia, hidden by perignyium beaks, apex acute or ultimate apex often rounded to retuse. <b>Perigynia</b> spreading to ascending, with beak and distal body of perigynium spreading or recurrent at 80º angle or greater, pale green to pale brown, conspicuously 3–6-veined abaxially, conspicuously 2–6-veined adaxially, ovate to elliptic, plano-convex, 2–3.5 times as long as wide, 2.7–4 × 1–1.7 mm, 0.3–0.4 mm thick, margin flat, including wing 0.1–0.2 mm wide, abruptly narrowed proximally, not extending to base; beak tip usually not colored, flat, ciliate-serrulate, distance from beak tip to achene 1.5–1.8 mm. <b>Achenes</b> oblong-ovate, 1.2–1.5 × 0.6–0.8 mm, 0.3–0.4 mm thick. <b>2n</b> = 70.</span><!--

|discussion=<p>When mature, <i>Carex cristatella</i> is readily distinguished from most other species of sect. Ovales by the widely spreading perigynia and the globose spikes, but immature specimens are frequently mistaken for other species, especially <i>C. bebbii</i>.</p>
