Tufted perennial to 0.9 m.

Notes

Fruiting May to June

Wetland indicator: UPL

Unlike other sedges with hairy leaves and culms, such as Carex hirtifolia and C. swanii, this species has smooth rather than hairy perigynia. Two other species in this section with both hairy sheaths and smooth perigynia are C. caroliniana (sheath glabrous ventrally) and C. bushii (sheath hairy throughout), both of which have spreading perigynia with short-pointed tips and conspicuous nerves.
