|discussion=<p>Species 1.</p><!--
--><p><i>Epifagus</i> is the only genus among the holoparasites to produce cleistogamous flowers. The relative occurrence of cleistogamous and chasmogamous flowers varies from plant to plant.</p><!--
--><p>The cormlike structure of <i>Epifagus</i> is entirely underground and differs from the stems of <i>Boschniakia</i>, <i>Conopholis</i>, and <i>Kopsiopsis</i> by having both scales and coralloid roots. The racemes emerge directly from the base; there is no aerial stem. Floral buds occur in the axils of all bracts, often even those on the cormlike base. Other genera of holoparasites have a well-differentiated vegetative stem that supports the inflorescence.</p>
