Description
Species Description - Much like no. 48 [Carex canescens L.]; lvs green, 1–2.5 mm wide; spikes avg smaller, 4–8 mm, brownish, or sometimes pale as in no. 48; perigynia mostly 5–10(–15), a little more spreading, so that the beak-apiculations interrupt the outline of the spike, evidently but rather finely several-nerved dorsally, nerveless or obscurely nerved ventrally, smoother-textured, the wall very thin distally and easily ruptured; dorsal suture well developed, 0.4–0.8 mm, extending onto the distal end of the body, often with a narrow, white-hyaline, overlapping longitudinal flap; 2n=56. Bogs and wet woods; circumboreal, s. to N.J., O., Mich., Minn., and in the mts. to N.C.
