THE OCCURRENCE OF LIVING AND SUB‐FOSSIL REMAINS OF BETULA NANA L. IN UPPER TEESDALE
S ummary A small colony of the arctic‐alpine dwarf birch, Betula nana , has been discovered in Upper Teesdale, this being the only English station for the species. It is elsewhere in Britain confined to the Scottish Highlands. The plant associations with which the species occurs throughout its range...
