Discussion
Ulota curvifolia is a Canadian shield species in eastern North America, with a range from the northern shore of Lake Huron and Lake Superior north to Hudson Bay and Baffin Island westward across the subarctic of the Northwest Territories and southward in the Canadian Rockies to Alberta and southern British Columbia. Ulota curvifolia grows on rock and has strongly papillose, thick-walled distal laminal cells and stiffly flexuose leaves. Ulota hutchinsiae has a more southerly distribution, less papillose distal laminal cells, and straight leaves. As with most other species of the genus, U. curvifolia has a rich chestnut brown coloration that helps identify it in the field.
