A snake pit is, in a literal sense, a hole filled with snakes. In idiomatic speech, "snake pits" are places of horror, torture and death in European legends and fairy tales. The Viking warlord Ragnar Lodbrok is said to have been thrown into a snake pit and died there, after his army had been defeated in battle by King Aelle II of Northumbria. An older legend recorded in Atlakviða and Oddrúnargrátr tells that Attila the Hun murdered Gunnarr, the King of Burgundy, in a snake pit. In a medieval German poem, Dietrich von Bern is thrown into a snake pit by the giant Sigenot – he is protected by a magical jewel that had been given to him earlier by a dwarf.[1]
Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
