Nisien is a figure in Welsh mythology, the son of Penarddun and Euroswydd and twin brother of Efnysien.[1] He appears in the Second Branch of the Mabinogi, which names Brân the Blessed, Branwen, and Manawydan as his half-siblings. Nisien, also Nissyen, was the opposite of his brother Efnisien in personality. He was tranquil and generous, while Efnisien was vindictive and destructive.

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.
