Kepler-25b is an extrasolar planet orbiting the star Kepler-25, located in the constellation Lyra.[4] The planet was first detected as a candidate extrasolar planet by the Kepler space telescope in 2011.[5] It was confirmed, in 2012, by Jason Steffen and collaborators using transit-timing variations obtained by the Kepler Space Telescope.[1]

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.
