STRUCTURALLY PRESERVED LEAVES OF HARRIMANELLA HYPNOIDES (ERICACEAE): PALEOECOLOGY OF A NEW NORTH AMERICAN LATE PLEISTOCENE FOSSIL
Plant macrofossils from the basal inorganic sediments at Tom Swamp, north central Massachusetts, contained leaves, seeds, and fruits of arctic‐alpine species, nearly all of which occur at present near the summits of Mt. Washington and Mt. Katahdin (New England) and in other alpine and arctic areas n...
