A COMMUNITY OF ARCTIC–ALPINE PLANTS ON THE EAST SHORE OF LAKE SUPERIOR
This paper reports the discovery of a community of arctic–alpine plants on the cliffs, rocky ledges, and boulder beaches along the south shore of Old Woman Bay. The site is located on the east shore of Lake Superior at approximately 47° 47′ N. lat., 84° 54′ W. long., in the District of Algoma, Ontar...
