Hosts of Viscum album

Summary The reported hosts of Viscum album include more taxa, than any other mistletoe, including Dendrophthoe falcata. From a review of the literature, we identified hosts among 452 species, subspecies, varieties, and hybrids in 96 genera of 44 families. Rosaceae has the most hosts with 128 taxa parasitized. Commonly infested genera include Salix, Populus, Acer, Malus, Crataegus, Prunus, Sorbus, Abies, and Pinus. The host range of V. album increased greatly with introduction of susceptible taxa into its native range and with spread of the mistletoe to new regions with rich floras, such as California.
