Where I grew up in Ireland, the plant "Bog Cotton" was called "Leprechaun's Beard." Tradition has some great themes and many of them may very well be based on fact. What annoys me is when the "experts" usually do something stupid. I watched a series recently called "Special Unit 2" and one of the so-called evil characters was male called the "Banshee". The word "Banshee" means "Fairy Woman" and as 'catters will know it is usually associated with the death of a person.
