In that post, I explained that Mistletoe is a hemi-parasite (only partially dependent on its host for survival) and that the family represents one of the nine times that parasitism evolved in the plant kingdom. I also mentioned that unlike most parasites, parasitic plants are keystone species, where their ecological impact is disproportionate relative to their abundance.
