Nomenclature
The maps are presented in their original form except when scientific and/or common names have changed. When name(s) have changed, the currently accepted scientific name and/or common name used in PLANTS Database has been added below the older name(s).

Distribution of tree species in North America. The links in the first column go to maps, and the links in the second column go to FEIS Species Reviews. Current names are in parentheses if nomenclature has changed.
