Sorry I can't site a source, but I recall reading somewhere that mistletoe 
resembles the host because, in part, because of hormones. Growth hormones 
in the host affect the shape of (host) leaves. When these are absorbed by 
the mistletoe the same hormones have a similar effect on the mistletoe leaves.
