Why are mistletoes called mistletoes?
Mistletoes don’t just exploit plants, they depend critically on animals to get around — a varied selection, it turns out. Their name derives from Anglo-Saxon words meaning “dung-on-a-twig” — typically the dung of birds, which eat the seeds and disperse them to new host plants. (There are exceptions: Some mistletoe genera make explosive fruits that hurl their seeds toward nearby trees, reaching distances of 10 meters or more.) Most mistletoe fruits are berries containing a single seed that’s surrounded by a sticky layer of goo called viscin, which cements the seed to a new host tree.
