Pseudotribos ("false chewing") is an extinct genus of mammaliaform that lived in Northern China during the Middle Jurassic some 165 million years ago, possibly more closely related to monotremes than to theria (placental and marsupial mammals),[1] although other studies indicate that these shuotheres are closer to therians than to monotremes.[2][3] The only known specimen was found in the Daohugou Bed in Inner Mongolia (41°18′N 119°12′E / 41.3°N 119.2°E: paleocoordinates 42°36′N 122°24′E / 42.6°N 122.4°E).[4][5]

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.
