|discussion=<p>Epifagus virginiana is an obligate parasite of the American beech, Fagus grandifolia (Fagaceae). Its range is coincident with that of its host, including disjunct occurrences in the highlands of Hidalgo and Tamaulipas, Mexico (J. W. Thieret 1969d, 1971). Different degrees of anthocyanin production among populations have led to the description of two trivial color forms. Local common names such as cancer-root, clap-wort, and flux-plant allude to the historical belief that the plant was efficacious medicinally for a number of ailments (Thieret 1971).</p><!--
