Type locality: Carex saltuensis may be regarded as based primarily on Carex vaginata var. altocaulis Dewey, the type locality of which is "Bergen, 20 miles west of Rochester," New York.
Distribution: Boggy thickets and woods, in calcareous districts, Labrador and Newfoundland to Yukon, and southward to northern New England, northern New York, upper Michigan, northern Minnesota, and British Columbia.
