Flora of North America accepts the following three subspecies and two varietiesofCarex viridula:[2][5]

As of December 2019, Kew's Plants of the World Online lists Carex viridula as a synonym of Carex oederi.[6]

There is also variety Carex viridula var. bergrothii (Palmgr.) B.Schmid (synonym Carex bergrothii Palmgr.).[7]
