Jan Versluys (1 September 1873 in Groningen – 22 January 1939 in Vienna) was a Dutch zoologist.
He studied biology at the University of Amsterdam, and afterwards participated on a scientific voyage to the Caribbean aboard the vessel Chazalie. In 1898 he obtained his doctorate from the University of Giessen, then in 1899/1900 served as an assistant to Max Carl Wilhelm Weber on the Siboga Expedition to the Netherlands East Indies. As a result of the mission, he published a monograph on Gorgonians, titled "Die Gorgoniden der Siboga-Expedition". Later on in his career, he worked as a professor of zoology at the universities of Ghent (from 1916) and Vienna (from 1925).[1] Versluys is known to have corresponded with, and had visited American paleontologist Barnum Brown in 1904.
Taxa with the epithet of versluysi commemorate his name, an example being the amphipod subspecies Niphargus longicaudatus versluysi.[2]

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.
