Loranthus is a genus of parasitic plants that grow on the branches of woody trees. It belongs to the family Loranthaceae, the showy mistletoe family. In most earlier systematic treatments it contains all mistletoe species with bisexual flowers, though some species have reversed to unisexual flowers, while most modern systematists treat it as a monotypic genus with the only species Loranthus europaeus Jacq. - the summer mistletoe or European yellow mistletoe. In contrast to the well known European or Christmas mistletoe (Viscum album L., Santalaceae or Viscaceae) this species is deciduous. The systematic situation of Loranthus is not entirely clear, and some showy mistletoes in Asia may be true parts of this genus.
