Tufted perennial to 60 cm; fertile stems triangular, reddish-purple at the base; basal sheaths purplish; leaves glabrous, over 12 mm wide; those of the sterile shoots elongate, often surpassing the fertile stems, margin roughened; leaves of fertile stems bladeless or nearly so, reduced to purplish sheaths; terminal spike staminate, 1-2 cm long, purplish, with a long peduncle; pistillate spikes two to four, 1-3 cm, scattered, the lowermost on a short basal peduncle to 2 cm; perigynia crowded and overlapping, 2-ribbed, with many fine nerves, sharply trigonous, outline elliptic, constricted to a short, oblique beak; achenes trigonous. 

Notes

Fruiting April to June

Wetland indicator: NA

Most sedges are difficult to identify without examining the perigynia, but this woodland sedge is quite distinct. Only a few sedges have leaves this broad and this is the only one that is deep green without a waxy appearance to the leaves. The leaves also tend to have a crinkly appearance which can help distinguish it from C. careyana. Another common name, seersucker sedge, is a reference to the similarity of the leaves to the puckered surface of seersucker fabric.
