Epifagus

Epifagus virginiana, commonly called beech drops (or beech-drops or beechdrops), is an obligate parasitic plant which grows and subsists on the roots of American beech. It is a member of the family Orobanchaceae. The genus Epifagus is monotypic—containing only E. virginiana. The name Epifagus derives from Greek "epi" meaning "on" or "upon", and "Fagus" which is the genus name of beech.

==Description== Beechdrops is a parasitic plant native to eastern North America. It entirely lacks chlorophyll and produces many brown stems up to 30 cm tall on which it bears small white and purple flowers that appear in July through October. The flowers have tubular, zygomorphic corollas ~8mm long containing a single style and four stamens. The dried flower stalks will persist throughout the winter. The flowers on the lower parts of the plant are cleistogamous (self-pollinating), while the tops of the stems have chasmogamous (cross-pollinating) flowers, which may be sterile.
