New York Natural Heritage Program
Bent Sedge
Carex styloflexa Buckl.

Habitat [-]
This sedge mostly occurs in wet habitats often along the edges of streams. It has also been documented in New York from wet pine barrens, damp thickets, swampy woods on the border of a brook, edge of rich woods, and a sphagnum bog. There is also one specimen known from thin soil on limestone ledges in woods. This habitat information is suspect (New York Natural Heritage Program 2005). Wet, sandy, acidic soils, around springs, seeps, and small streams, under deciduous or mixed deciduous-evergreen forests (Bryson and Naczi 2002). Wet woods and bogs, often in sandy or silty soil (Gleason and Cronquist 1991). Low woods, wet moss, peaty spring-heads, etc. (Fernald 1970).

Associated Ecological Communities [-]
  • Coastal plain poor fen*
    A wetland on the coastal plain fed by somewhat mineral-rich groundwater and slow decomposition rates of plant materials in the wetland (and thus develops peat). Plants are generally growing in peat composed primarily of Sphagnum mosses with some grass-like and woody components.

    * probable association but not confirmed
  • Floodplain forest
    A hardwood forest that occurs on mineral soils on low terraces of river floodplains and river deltas. These sites are characterized by their flood regime; low areas are annually flooded in spring, and high areas are flooded irregularly.
  • Pine barrens vernal pond*
    A seasonally fluctuating pond and its associated wetlands that typically occurs in pine barrens. The water is intermittent, usually a pond in the spring but sometimes losing water through the summer to become a mostly vegetated wetland at the end of the summer. These ponds and wetlands may be small.

    * probable association but not confirmed
  • Red maple-hardwood swamp
    A hardwood swamp that occurs in poorly drained depressions, usually on inorganic soils. Red maple is usually the most abundant canopy tree, but it can also be codominant with white, green, or black ash; white or slippery elm; yellow birch; and swamp white oak.
  • Red maple-sweetgum swamp*
    A hardwood swamp that occurs on somewhat poorly drained seasonally wet flats, usually on somewhat acidic soils. Red maple-sweetgum swamps often occur as a mosaic with upland forest communities. Sweetgum is often the dominant tree or may be codominant with red maple. Other codominant trees include pin oak and blackgum.

    * probable association but not confirmed
  • Shallow emergent marsh*
    A marsh meadow community that occurs on soils that are permanently saturated and seasonally flooded. This marsh is better drained than a deep emergent marsh; water depths may range from 6 in to 3.3 ft (15 cm to 1 m) during flood stages, but the water level usually drops by mid to late summer and the soil is exposed during an average year.

    * probable association but not confirmed
