Cosmoptychius is an extinct genus of freshwater and estuarine ray-finned fish that lived during the Mississippian epoch.[1][2] It contains a single species, C. striatus from the Visean of Scotland.[3] It has a wide stratigraphic range in the Wardie Shale, with many specimens known.[4][5]
Initially classified as either a palaeonisciform (a now-paraphyletic group of basal actinopterygians)[6] or the earliest stem-group neopterygian, it is now generally considered a stem-group actinopteran.[7]

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.
