Synonymy. Carex macloviana was described from Falkland Islands, Port Louis, type in P;

Carex pachystachya was described from Unalaska.

Ecology and habitat. Found on grassy southfacing slopes in subarctic-alpine.

North American distribution. Eastern and western North America and Greenland, Eurasia and South America (Porsild 1957). Not yet reported for the Arctic Archipelago; subarctic-alpine, east North America and Greenland, Scandinavia, and South America (Porsild 1957). Alaska, Yukon, continental Northwest Territories, northern Quebec, Labrador.

Northern hemisphere distribution. Amphi-Atlantic (slightly), or North American. Northern Iceland, Labrador – Hudson Bay, West Greenland, East Greenland.

General notes. Porsild (1957) mentioned this taxon under the description of C. chordorrhiza as having a subarctic-alpine distribution. It has not yet been reported on the Arctic Archipelago, but it is in Greenland. It has a very scattered, disjunct distribution in the east (P. Ball, personal communication, 1998). No specimens from the Arctic islands at CAN (1998).

Since Porsild (1957), the Flora of North America treatment has accepted Carex pachystachya as a species different from C. macloviana, and maybe the taxon Porsild implied should be looked for in the Arctic islands.
