|---|---|---|---|---|---|
| Cyperaceae | Carex barrattii | Barratt's Sedge | Peaty bogs and marshes, especially in depression ponds, depression swamps, and sinkhole ponds, but also in seepage, such as Piedmont boggy streamheads. | Connecticut south to North Carolina (at least formerly), on the Coastal Plain, and disjunct inland in places with many Coastal Plain affinities, as in w. Virginia (Augusta County), sw. North Carolina (Henderson County, where now apparently extirpated), nw. South Carolina, sc. Tennessee (Coffee and Warren counties), n. Georgia, and n. Alabama. Reported for South Carolina by Hill & Horn (1997) and Horn (1999). See Ungberg (2022) for discussion of its occurrence in North Carolina. |  (c) Ward, Scott G |
| Cyperaceae | Carex limosa | Mud Sedge | Bogs, swamps, wet meadows, medium to poor fens and bogs. | Circumboreal, south in North America to se. Pennsylvania (Dauphin County, Rhoads & Klein 1993; Rhoads & Block 2007), New Jersey, Delaware (historical), Ohio, Indiana, Nebraska, Utah, and California. More commonly northward in a variety of medium to poor peatlands. This inherently northern species of peatland habitats does occur very sparingly southward to portions of our region. It is extirpated from Delaware and is now apparently extant in only one or a few location(s) each in New Jersey and Ohio; but locally abundant and probably S3 in Pennsylvania (S. Grund, pers. comm., 2023). Carex limosa was likely never legitimately collected from s. Indiana and is considered S1 in the northern portions of the state (S. Namestnik, pers. comm., 2023). |  (c) Ward, Scott G |
| Cyperaceae | Carex paupercula | Boreal Bog Sedge | Sphagnum bogs, boggy swamps. | Circumboreal, south in North America to n. New Jersey, c. Pennsylvania, Michigan, Wisconsin, Minnesota, New Mexico, and Washington. |
