yellowish or brown, without trace of red or purple at base. |
obtusely trigonous in cross section, (25–)35–125 cm, smooth. |

ligules 1.5–13(–18) mm, narrower to wider than long; blades yellowish or light green, M-shaped to flat, widest leaves of vegetative shoots (3.5–)4–12 mm wide, smooth or sometimes papillose adaxially, especially distally. |
racemose, with 2–6 spikes; proximal bracts leaflike, sheathing, sheath 4+ mm, longer than diameter of stem; lateral spikes pistillate or distal lateral spike androgynous, pedunculate, prophyllate; terminal spike staminate. |
(3–)15–50 cm; bract sheaths prolonged, apex truncate to convex; proximal (1–)2–4 spikes usually androgynous or, occasionally, pistillate, erect or the proximal spreading, ovoid to short cylindric. |
spreading to somewhat reflexed, rarely ascending, veined, stipitate, ovate or lanceolate, round or rounded-trigonous in cross section, base round-tapering, apex tapering or, rarely, contracted to beak, glabrous; beak, when present, bidentate, teeth erect. |
spreading to somewhat reflexed, pale green, 20–26-veined, essentially uninflated, lanceolate, (8.3–) 10.5–13.5(–15) × 1.5–2.4 mm, 4–7 times as long as wide, apex tapered to bidentulate; beak absent. |

Carex lonchocarpa, often regarded as a variety of C. folliculata, is smaller than C. folliculata and usually has narrower leaves, fewer lateral spikes (these usually with a staminate apex and erect or spreading), shorter but relatively broader achenes, shorter pistillate scales, and narrower perigynia that are somewhat reflexed at maturity. Substantial differences in achene micromorphology also support recognition of C. lonchocarpa as a distinct species (D. E. Wujek and F. J. Menapace 1986). The ranges of these two taxa are largely allopatric, although they overlap slightly in southern Virginia, eastern Maryland, and Delaware.

1. Perigynia ovate to narrowly ovate, 2.6–3.9 times as long as wide, 6.4–10.7 mm, apex contracted; beak 1.3–3 mm. | C. turgescens |
1. Perigynia lanceolate, 4–7 times as long as wide, (8.3–)10.5–15.6 mm, apex gradually tapered, bidentulate; beak absent. | → 2 |
2. Widest leaf blades 1.6–3.5(–4.2) mm wide; bract sheaths concave at apex; anthers 1.1– 2.7 mm. | C. michauxiana |
2. Widest leaf blades (3.5–)5–18 mm wide; bract sheaths prolonged, truncate to convex at apex; anthers 3–5 mm. | → 3 |
3. Larger achenes 3.4–4(–4.5) mm, (1.7–)1.8–2.4 times as long as wide; lateral spikes entirely pistillate (occasionally a few empty scales at apex), the proximal usually arching or nodding; widest leaves of vegetative shoots 8–18(–21) mm wide; proximal pistillate scales mostly 2/3 as long as to slightly longer than perigynia. | C. folliculata |
3. Larger achenes 2.3–3.4(–3.8) mm, 1.3–1.8 times as long as wide; lateral spikes usually with conspicuous staminate apex, erect or spreading; widest leaves of vegetative shoots (3.5–)5–12 mm wide; proximal pistillate scales mostly 1/2–2/3 as long as perigynia. | C. lonchocarpa |
