Beechdrops (Epifagus virginiana) is an obligate parasitic plant that obtains nutrients directly from the American beech.
Description and Taxonomy
The beechdrops plant belongs to the family Orobanchaceae. The genus Epifagus is monotypic, containing only E. virginiana. The name Epifagus derives from the Greek "epi", meaning "on" or "upon", and "Fagus" which is the genus name of beech.[1]
Life Cycle
A fairly inconspicuous brown stem produces two types of flowers, cleistogamous flowers that self-pollinate without ever opening, and chasmogamous flowers that open, but are often sterile.
Hosts and Impacts
Beechdrops grows on shallow roots at varying distances from the trunk of F. grandifolia. The parasite develops a haustorium that grows into beech roots to draw nutrients from its host, as beechdrops does not photosynthesize. E. virginiana does not tolerate disturbances in its connection to F. grandifolia.
