Janibacter hoylei is a species of Gram positive, aerobic, bacterium.[1] The species was initially isolated from cryovials that sampled high altitude air between 20 and 41 km above sea level. The species was first described in 2009, and the species is named after English astronomer Fred Hoyle. Two other new species were discovered during the same survey: Bacillus isronensis and Bacillus aryabhattai.
The optimum growth temperature for J. hoylei is 25-30 °C, and can grow in the 20-40 °C range. The optimum pH is 9.0, and can grow at 5.0-10.0. The species is more resistant to UV radiation than other members of Janibacter.[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.
