Aureolaria levigata, commonly known as entireleaf yellow false foxglove[2] or Appalachian oak-leech,[3] is a species of flowering plant in the family Orobanchaceae.
It is native to much of the Appalachian Mountains and surrounding areas in the eastern United States.
Like other members of its genus, Aureolaria laevigata is hemiparasitic on oak tree roots.
It can be distinguished from its relative, A. flava by its tendency to have entire, simple leaves.
[7] The scientific name is frequently "corrected" as Aureolaria laevigata,[2][8] though according to the Germplasm Resources Information Network, "Rafinesque consistently spelled this "levigata" and there is no basis for correcting his spelling".
