Comet 30P/Reinmuth, also known as Comet Reinmuth 1, is a periodic comet in the Solar System, first discovered by Karl Reinmuth (Landessternwarte Heidelberg-Königstuhl, Germany) on February 22, 1928.
First calculations of orbit concluded a period of 25 years, but this was revised down to seven years and speculation this was the same comet as Comet Taylor, which had been lost since 1915. Further calculations by George van Biesbroeck concluded they were different comets.
The 1935 approach was observed though not as favourable, in 1937 the comet passed close to Jupiter which increased the perihelion distance and orbital period.
Due to miscalculations, the 1942 appearance was missed, but it has been observed on every subsequent appearance since.
The comet nucleus is estimated to be 7.8 kilometers in diameter.[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.
