A woody, obligate hemiparasitic plant with leaves that perform some photosynthesis, insignificant flowers, and fruits that are berries containing several seeds in a very sticky juice. After birds (commonly mistle thrushes) have picked the berries they clean their bills by wiping them on tree branches, thereby transferring the seeds to a new host. There are 70–100 species of mistletoes in the genus Viscum (family Santalaceae), found in temperate and tropical Eurasia, Africa, and Australia.
