USNA Herbarium Botanical Type Specimens

     
     

This is a checklist of plants growing, without cultivation, on the grounds of the U.S. National Arboretum.
The checklist is comprehensive for native species known to be naturally occurring on the grounds.
The checklist includes many introduced exotic species which are established in our region. 
The checklist also contains a certain number of local escapes from plants cultivated at the National Arboretum.
However, the checklist is by no means comprehensive of the many plants that fit the latter category.

Oliver M. Freeman, former Botanist and Curator of the Living Plant Collections, published the
Annotated List of Plants Growing Naturally at the National Arboretum
in 1953.
Originally based on Freeman’s publication, the checklist below has been augmented by more recent collections. 
Many names have been updated to reflect changes in taxonomy. 
All species listed are documented with herbarium specimens preserved in the National Arboretum Herbarium.
