A Welsh pigmy elf. They haunt the groves and valleys. They are said to be the wandering souls of ancient druids, too good for hell and not good enough for heaven.
The bells of the Digitalis or fox-glove are called Menyg Ellylon, "Elves'-gloves." In the park of Sir Robert Vaughan these was a celebrated old oak-tree named Crwben-yr-Ellyll, or "the Elf's Hollow-tree."
