Sparagmite (from the Latin sparagma, meaning "fragment") is an arkosic sandstone, greywacke and conglomerate set of beds so named by Jens Esmark in 1829.[1] Deposited in what is now Scandinavia during the Neoproterozoic Era to early Cambrian time,[2] the sparagmite nappes were transported up to several hundred kilometers during the Caledonian collision. Sparagmite is characterized by high feldspar percentages of microcline.[3][4]

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.
