Moist, open forests, especially along floodplains.

A distinctive species, forming colonies by unique, long (to 2 m!) tip-rooting stolons, with leaf blades near the ends reduced and reflexed, that snake along the forest floor. The perigynia are hard-walled, scabrous, and number only ca. 3–8 per spike. First collected by S. P. Voice in Gogebic Co. in 1980.
