NGC 2998 is a barred spiral galaxy located in the constellation Ursa Major.[5] It is 195 million light-years (59.7 megaparsecs) away from the Earth.[3] It is an intermediate spiral galaxy.[5] Its stellar mass is about that of the Milky Way.[6]
NGC 2998 is a member of the eponymous NGC 2998 group, a relatively dense galaxy group which also includes NGC 3002, NGC 3005, NGC 3006, NGC 3008 and a few others.[7][6]

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.
