Carex chordorrhiza A. A. Reznicek

Sphagnum bogs, peaty lake shores (especially foating mats), the wettest parts of fens, and wet sites in interdunal hollows.

Though quite unrelated, Carex chordorrhiza shares with C. limosa, of similar habitats, true vegetative culms that elongate after flowering and fruiting, to form leafy prostrate stolons up to a meter long that function in vegetative spread, especially extending mats. The stolons of C. chordorrhiza are very similar to those of C. limosa, but can be distinguished because they tend to be yellow-green, not glaucous, and lack reddish pigmentation on the sheath bases.
