From Flora of Indiana (1940) by Charles C. Deam
Infrequent in the lake area (mostly in the dune region) where it grows along the wet sandy edges of swales in the dunes and on old lake beds, chiefly in calcareous soils. It is frequently associated with Carex crawei, C. tetanica, C. meadii, C. viridula, and C. haleana. Apparently it was formerly more plentiful than at present as collections from the Indiana dunes forty and fifty years ago are much more numerous in herbaria than recent collections. At Pine, where this species is closely associated with Carex tetanica, plants of the latter species showing many characteristics of C. Garberi and plants of C. Garberi having characteristics of C. tetanica are frequent. The general aspect of such plants and the conditions under which they are found are strongly suggestive of hybridization.
