Mistletoe in trees

There are a few of these trees off the Nash Road here in Newport where you see clumps in the branches.and these clumps are the start of mistletoe.
Mistletoe is the common name for obligate hemiparasitic plants in the order Santalales. They are attached to their host tree or shrub by a structure called the haustorium, through which they extract water and nutrients from the host plant. Their parasitic lifestyle has led to some dramatic changes in their metabolism.
