Several specimens of the pteridosperm Medullosa anglica Scott are described from coal balls of Lower Pennsylvanian age from eastern Kentucky, U.S.A. These stems are remarkably similar anatomically to those originally described by Scott from the Lower Coal Measures, and represent the first critically examined material of this taxon from North America.
