About

Scope. This work treats all federally listed species of vascular plants and lichens occurring in North Carolina, as well as their congeners or otherwise morphologically similar species. There are several hundred state listed species in North Carolina, but state listed species are only treated here if they occur in a genus that includes at least one federally listed species in the State. An exception of note is Carex--the largest genus of vascular plants in North Carolina--for which only the federally listed species is treated. Strictly speaking of course, lichens are not plants. We include the single federally listed lichen (in North Carolina) here in part based on historical expectations. This work is not intended as an introduction to plant identification or basic botany. Instead it has been developed as a resource for enhanced field identification and survey for advanced users, including practicing environmental professionals, agency biologists, and higher level students.

Status codes (e.g., E [endangered], T [threatened], G1 [globally critically imperiled], S1 [critically imperiled in the state], etc.) follow the US Fish & Wildlife Service, the NC Plant Conservation Program, and the NC Natural Heritage Program. For an explanation for each code, please see the NC Natural Heritage Program [external link].
