Arctops ("Bear face") is an extinct genus of gorgonopsian therapsids known from the Late Permian of South Africa. It measured up to 2 metres (6 ft 7 in) in length and its skull was 30 centimetres (12 in) long.[1] The type species is Arctops willistoni. A second species, A. watsoni, may be synonymous with A. willistoni. A. kitchingi may be a third species of Arctops, but it was only tentatively assigned to the genus when it was first named.[2] Both were formally synonymized with A. willistoni by Christian Kammerer in 2017.[3]

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.
