Soft Rush is easily found and easily identified. Read more at Vascular Plants of North Carolina.
Distinguished by the easily compressible stems (giving the common name “Soft Rush”, and very different than the tough, wiry culms of another common and widespread species, Juncus coriaceus), fine stem ridges that are not pronounced, and tepals that +/- equal the tepals.
