CoRoT-15 is an eclipsing binary star system about 4,500 light-years (1,400 parsecs) away in the constellation Monoceros, discovered by the CoRoT space telescope in 2010. It consists of an F7V star and an orbiting brown dwarf companion, which was one of the first transiting brown dwarfs to be discovered.[4]

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.
