--><span class="statement" id="st-undefined" data-properties=""><b>Rhizomes </b>0.2–10 cm, 0.6–1.2 mm in diam. <b>Culms</b> arising singly or in loose tufts of 2–6(–12), 10–40(–60) cm, apically slightly scabrous. <b>Leaves</b>: proximal 1–4 reduced to bladeless or nearly bladeless sheaths; foliage leaves 1–2(–3) per culm; ligules about as wide as long; blades mostly 1–3 (proximal blade) or 5–13 (distal) cm × 0.5–1.6 mm. <b>Spike</b> consisting of slender terminal cone of (1–)2–4 staminate flowers and (1–)2–6(–7) pistillate flowers, 3–10 (often 5–8) × 2–8 (immature fruit) or to 17 (mature fruit) mm. <b>Pistillate</b> scales 3.7–5.9 mm, wider than and 2/3 length of perigynia. <b>Staminate</b> scales closely appressed. <b>Perigynia</b> light green, becoming straw colored or pale brown, lance-subulate to narrowly elongate-oblong, (5–)5.9–7.8 × 0.7–1.1 mm, long-tapering; beak indistinct; rachilla vestigial. <b>Achenes</b> 2–2.4 × 0.8–1 mm; style exserted 0.2–1.3 mm beyond orifice of beak. <b>2n</b> = ca. 74, 76.</span><!--

|discussion=<p><i>Carex pauciflora</i> is sometimes confused with <i>C. microglochin</i>, though <i>C. pauciflora</i> is easily distinguished by the lack of an evident rachilla. Compared to <i>C. microglochin</i>, the shoots of <i>C. pauciflora</i> tend to be more definitely tufted, the culms are more sharply 3-angled and roughened distally, and the achenes fill less of the perigynia. <i>Carex pauciflora</i> has a catapult dispersal mechanism (E. E. Hutton 1976) in contrast to the putative clinging mechanism of <i>C. microglochin</i> and presumably C. camptoglochin V. I. Kreczetowicz and C. parva Nees (see comments under the previous species). Dispersal by animals is possible for <i>C. pauciflora</i> as well. People walking through bogs may find perigynia attached to their clothing (L. Brouillet, pers. comm.).</p>
