--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>usually loosely cespitose; rhizomes short, congested. <b>Culms</b> trigonous in cross section, 8–90 cm, scabrous distally. <b>Leaves</b>: basal sheaths reddish brown; ligules as wide as to slightly longer than wide; blades mid to dark green, V-shaped, sometimes with revolute margins, 0.9–6.3 mm wide, glabrous. <b>Inflorescences</b> 2.5–14(–20) cm; proximal bract 0.6–16(–29) cm, shorter than or equaling inflorescence; proximal 1–3 spikes pistillate, erect or the proximal often pendent; terminal 1–3 spikes staminate. <b>Pistillate</b> scales ovate, 1.9–4.3(–5) × 0.9–2.1 mm, as long as or shorter than perigynia, margins entire, apex obtuse or acute, awnless. <b>Perigynia</b> ascending, often dark-colored, obscurely few-veined, veins not running to beak, tightly investing achene, elliptic, 2.2–5.5 × 1.1–2.9 mm, apex abruptly contracted; beak 0.2–0.8 mm, bidentulate, teeth straight, to 0.3 mm. <b>Stigmas</b> 2. <b>Achenes</b> yellow, biconvex, smooth. <b>2n</b> = 78, 80.</span><!--

|discussion=<p><i>Carex saxatilis</i> is highly variable in North America. Plants from western North America, often named C. physocarpa, tend to be robust with long peduncles on the pistillate spikes, wide leaves, and large perigynia. These characters decrease in size eastward across North America with successively smaller plants usually referred to as <i>C. saxatilis</i> and C. miliaris. This weak east/west cline is confounded by large amounts of variation within small geographic areas and phenotypic plasticity. B. A. Ford et al. (1991) and B. A. Ford and P. W. Ball (1992) have demonstrated that these segregates represent elements in a continuum rather than discrete taxa.</p><!--
--><p>Hybrids between <i>Carex saxatilis</i> and <i>C. vesicaria</i> (= C. ×stenolepis Lessing; = C. ×mainensis Porter ex Britton) and <i>C. saxatilis</i> and <i>C. utriculata</i> (= C. ×physocarpoides Lepage) have been found in North America (B. A. Ford et al. 1993). These hybrids are infrequent, largely sterile, and intermediate in morphology between the two parents.</p>
