| Cyperaceae | Carex atlantica | Prickly Bog Sedge | Bogs and seepages. | Nova Scotia west to Michigan and nw. Indiana, south to ne. Florida, Panhandle Florida, and e. Texas. |  (c) Ward, Scott G |
| Cyperaceae | Carex echinata ssp. echinata | Star Sedge | Bogs, seeps, fens. | Ssp. echinata is circumboreal, ranging in North America from Newfoundland and Labrador (Newfoundland) west to Saskatchewan, south to Delaware, Pennsylvania, Indiana, Iowa, and North Dakota, and in the mountains to w. North Carolina, nw. South Carolina {Bradley et al. [in prep.]), and e. Tennessee; also in w. North America from Alaska (Aleutians) and British Columbia south to Colorado, Utah, and s. California. |  (c) Fleming, Gary P. |
| Cyperaceae | Carex exilis | Meager Sedge, Exiled Sedge | Peaty seepage bogs. | Newfoundland and Labrador (Newfoundland) and Newfoundland and Labrador (Labrador) west to Ontario and n. Minnesota, south to New Jersey, Delaware, Maryland, New York, n. Michigan, n. Wisconsin, and n. Minnesota; disjunct southward in the Atlantic Coastal Plain of sc. North Carolina and in the Gulf Coastal Plain of se. Mississippi, sw. Georgia, and sw. Alabama. The southern occurrences are remarkably disjunct from the Canadian, northern Coastal Plain, and Great Lakes distribution. Initially discovered in Georgia e. of Columbus (Marion County) by Tom Patrick and recently confirmed by Joyce Klaus (S. Ward, pers. comm., 2023). It also seems likely that this species awaits discovery in far western Florida, given the abundance of seepage slopes, and discoveries in nearby Mobile and Baldwin counties, Alabama (Orzell and Bridges 1991). |  (c) Ward, Scott G |
| Cyperaceae | Carex howei | Howe's Sedge, Prickly Bog Sedge | Bogs and seepages, often growing in Sphagnum. | Nova Scotia west to Michigan and nw. Indiana, south to c. peninsular Florida and e. Texas, predominantly (but by no means strictly) on the Coastal Plain; Dominican Republic. |  (c) Ward, Scott G |
| Cyperaceae | Carex interior | Inland Sedge | Calcareous or ultramafic seeps, fens, and wet meadows. | Newfoundland and Labrador (Newfoundland) and Newfoundland and Labrador (Labrador) west to s. Alaska, south to w. Virginia, n. Arkansas, n. Arizona, and n. California; disjunct in Mexico (Chihuahua) (but not in Villaseñor 2016). |  (c) Fleming, Gary P. |
| Cyperaceae | Carex ruthii | Ruth's Sedge | Seepage areas, in forest or open areas. | A Southern Appalachian endemic: sw. Virginia south through w. North Carolina and e. Tennessee to nw. South Carolina and n. Georgia. |  (c) Fleming, Gary P. |
| Cyperaceae | Carex seorsa | Weak Stellate Sedge | Swamp forests in acid, organic soils. | Massachusetts south to Georgia and Panhandle Florida in the Coastal Plain, scattered inland westward to New York, Ohio, Michigan, Indiana, Arkansas, and Tennessee. |  (c) Brinker, Samuel - CC-BY-NC, permission granted to NCBG |

Virginia (Grayson County), ne. Tennessee (formerly), nw. North Carolina (Alleghany County, P. McMillan 2454), Illinois, and Missouri. First reported for Virginia by Wieboldt et al.
