Epiphyllous bryophytes in the Appalachian Plateau of Kentucky and Tennessee, U.S.A

Epiphyllous bryophytes are poorly documented for temperate eastern North America. Ten liverwort taxa and one moss species are reported as epiphylls on Rhododendron maximum from the Appalachian Plateau (Fentress County, Tennessee, and Menifee County, Kentucky).
