In this circumscription, the family includes the several genera of mistletoes.However, the APG II system of 2003 does not recognize the family, treating it as a synonym of Santalaceae. Genera once treated as belonging to family Viscaceae include:ArceuthobiumDendrophthoraGinalloaKorthalsellaNotothixosPhoradendronViscum
