--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>densely cespitose; rhizomes horizontally spreading to ascending, reddish brown, 17–75 mm, stout. <b>Culms</b> 5–17 cm, scabrous distally; bases (remnants of old leaves) weakly fibrous. <b>Leaf</b> blades green, occasionally glaucous, exceeding culms, 1.7–3 mm wide, herbaceous, papillose to scabrous abaxially, papillose to scabrous adaxially. <b>Inflorescences</b> with both staminate and pistillate spikes; peduncles of staminate spikes 0.3–1.2 mm; proximal cauline bracts leakflike, shorter than inflorescences. <b>Spikes</b>: proximal pistillate spikes 2–3 (basal spikes 0); cauline spikes overlapping, proximal 2 separated by less than 7 mm, with 4–8 perigynia; staminate spikes (3–)6.1–9.3 × 1.1–1.7 mm. <b>Scales</b>: pistillate scales pale to dark reddish brown, with narrow white margins, ovate to lanceolate, 2.7–4.2 × 1.2–2 mm, shorter than to equaling perigynia, apex acute to acuminate or short-aristate; staminate scales lanceolate, 2.8–4 × 1.2–1.8 mm, apex obtuse or acute to acuminate. <b>Anthers</b> 1.8–2 mm. <b>Perigynia</b> pale green, veinless, ellipsoid, 3–4.1 × 0.9–1.4 mm; beak straight, pale green, 0.6–0.9 mm, weakly ciliate-serrulate, apical teeth 0.1–0.3 mm. <b>Stigmas</b> 2(–3). <b>Achenes</b> brown, ellipsoid, biconvex, flattened-trigonous, or evenly trigonous with convex sides (all three types may occur on the same plant), 1.5–2 × 0.9–1.3 mm.</span><!--

|discussion=<p><i>Carex floridana</i> usually has been recognized as a distinct species in recent years; the distinctions from <i>C. nigromarginata</i> are subtle. To further complicate matters, some specimens are incomplete, lacking either complete bases or mature perigynia, rendering them unidentifiable. We have retained the two taxa at specific rank; further examination of their morphology, cytology, and ecology is warranted.</p>
