--><p>Echinacea laevigata was historically present in Pennsylvania but is now thought to be extirpated; its occurrence in Maryland has not been confirmed; reports of its presence in Alabama and Arkansas are most likely based on misidentifications. It is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
