|---|---|---|---|---|---|
| Cyperaceae | Carex albursina | White Bear Sedge | Nutrient-rich cove forests (and less commonly in drier forests), over mafic or calcareous rocks. Rich mesic forests further northward. | Vermont and s. Québec west to Minnesota, south to South Carolina (P. McMillan pers. comm. 2003, specimen at CLEMS), nw. Georgia, Mississippi (Dorey & Bryson 2016), ne. Alabama (S. Ward, pers. obs. 2022), and Arkansas. |  (c) Fleming, Gary P. |
| Cyperaceae | Carex blanda | Eastern Woodland Sedge, Charming Sedge | Cove forests, bottomlands, and other mesic, nutrient-rich forests. | Maine and s. Québec west to North Dakota, south to c. Georgia (Jones & Coile 1988), n. peninsular Florida, Panhandle Florida, and Texas. |  (c) Goldman, Douglas - CC-BY-SA |
| Cyperaceae | Carex crebriflora | Coastal Plain Sedge | Bottomland and other nutrient-rich forests. | Virginia, Kentucky, and Arkansas south to n. peninsular Florida and Panhandle Florida and Texas. |  (c) Sorrie, Bruce A. - CC-BY |
| Cyperaceae | Carex gracilescens | Slender Loose-flowered Sedge | Moist, nutrient-rich forests, calcareous hammocks. | Vermont and s. Québec west to Wisconsin, south to South Carolina, Alabama, Louisiana, and e. Texas; disjunct in sw. Georgia and Panhandle Florida. |  (c) Ward, Scott G |
| Cyperaceae | Carex ignota | Incognito Sedge, Incognito Lined Sedge | Mesic slope and ravine forests, upper terraces of floodplains in bottomland hardwood forests. | E. South Carolina south to n. Florida, west to w. Tennessee, e. Texas, and Arkansas. |  (c) Bridges, Edwin |
| Cyperaceae | Carex kraliana | Kral's Sedge | Mesic forests, slightly acidic to circumneutral. | Maryland, West Virginia (Vanderhorst et al. 2019), Ohio, and Indiana south to Panhandle Florida and Texas. |  (c) Ward, Scott G |
| Cyperaceae | Carex laxiflora | Broad Loose-flowered Sedge | In a wide range of moist to dry, acidic to nutrient-rich forests. | Newfoundland and Labrador west to Ontario, south to Georgia, Florida Panhandle, Mississippi, and Louisiana. |  (c) Fleming, Gary P. |
| Cyperaceae | Carex leptonervia | Nerveless Woodland Sedge | Nutrient-rich forests, such as rich, seepy northern hardwoods forests. | Newfoundland and Labrador (Newfoundland) west to Minnesota, south to New Jersey, Pennsylvania, Indiana, and Wisconsin, and in the Appalachians south to North Carolina and South Carolina (L.L. Gaddy, pers.comm., 2009). |  (c) Fleming, Gary P. |
| Cyperaceae | Carex manhartii | Blue Ridge Purple Sedge, Manhart's Sedge | Cove forests and montane oak-hickory forests, mostly at medium to fairly high elevations, especially over mafic rocks (such as amphibolite) and calcareous rocks (such as marble), but occurring on more acidic substrates as well. | Endemic to s. West Virginia, sw. Virginia, w. North Carolina, nw. South Carolina, ne. Georgia, and se. Tennessee, in the Blue Ridge Mountains. Once considered very rare, this species is now known to be locally common in portions of sw. North Carolina and adjacent ne. Georgia. For more information on the Virginia occurrence, see Belden et al. (2004). |  (c) Ward, Scott G |
| Cyperaceae | Carex ormostachya | Necklace Spike Sedge | Northern hardwood forests. | S. Canada south to Maine, Massachusetts, Pennsylvania, w. Virginia (Augusta County), e. West Virginia, n. Ohio, Michigan, and Wisconsin. |  (c) Wiegersma, Quinten - CC-BY |
| Cyperaceae | Carex purpurifera | Limestone Purple Sedge | Moist, rich cove forests, at low elevations, over calcareous or mafic rocks. | West Virginia (Vanderhorst et al. 2019), w. Virginia and Kentucky south to n. Georgia and n. Alabama, mostly west of the Blue Ridge Mountains, but with scattered disjunct populations on calcareous or mafic sites in the Blue Ridge. |  (c) Ward, Scott G |
| Cyperaceae | Carex radfordii | Radford's Sedge | Very nutrient-rich, moist cove forests in the Blue Ridge Escarpment region, over calcareous or mafic rocks (especially along the Brevard Fault). | Endemic to the Blue Ridge Escarpment of sw. North Carolina, nw. South Carolina, and ne. Georgia. |  (c) Ward, Scott G |
| Cyperaceae | Carex striatula | Lined Sedge | Bottomland and other nutrient-rich forests. | Connecticut, se. New York, Pennsylvania, s. Ohio, and w. Kentucky south to n. Florida, Panhandle Florida, and s. Mississippi. Former attribution of a wider distribution to the west (west of the Mississippi River) represents Carex ignota. |  (c) Sorrie, Bruce A. - CC-BY |
| Cyperaceae | Carex styloflexa | Bent Sedge | Bogs, wet forests, acid stream swamps. | Connecticut west to s. Ohio, south to c. peninsular Florida and se. Texas. Reported from Ashley Co., Arkansas (Sundell, Hartrick & Hartrick 6632), but the spikes, perigynium beaks and habitat description don't match this species (S. Ward, pers. obs.; 2025); they are likely instead C. ignota. |  (c) Ward, Scott G |
