Abstract

Meesia triquetra (Richt.) Aongstr. occurs in rich fens having surface waters with high pH and calcium concentrations. The present day distribution of M. triquetra in North America and Greenland is documented from Alaska and British Columbia east to Newfoundland and Ellesmere Island, N.W.T., and south to northern California in the west and Pennsylvania in the east. A large number of collections have been made from the mountains and foothills in Alaska, British Columbia, and Alberta; also notable are the many collections from the Great Lakes area. All Quaternary subfossil records lie in the same geographic area as extant records except for one station in Iowa and another in southern Ohio, both of which lie south of the present-day range.
