- Dewey, Amer. J. Sci. Arts 29: 246 (1836). Holotype (GH): Canada: "Summits of Rocky Mountains" probably Alberta, west of Jasper, leg. Drummond 283.
Geography: Amphi-Beringian - Cordilleran & North American (NE).
Notes: Murray and Elven: Ball and Zoladz (1994) investigated the North American variation in Carex petricosa. They did not find enough variation in the west and northwest to merit rank for some varieties described from there. They found the geographically isolated northeastern plants to differ sufficiently to be recognized as a variety.
