NGC 2074 is a magnitude ~8 emission nebula in the Tarantula Nebula located in the constellation Dorado. It was discovered on 3 August 1826 by James Dunlop and around 1835 by John Herschel. It is described as being "pretty bright, pretty large, much extended, [and having] 5 stars involved".[3]
Discovery
Some of the objects catalogued by Herschel before 1847 do not have a discovery date listed, and NGC 2074 is one of them. Though its inclusion in the catalog of objects observed in the Large Magellanic Cloud which involves observations carried out between 2 November 1836 and 26 March 1837 shows it must not have been discovered later than that.[3]
The observation of NGC 2074 by Dunlop was not identified as this object until recently.[3]
Location
NGC 2074 is located around 170,000 light-years (1.1×1010 AU) away. The area has a lot of raw stellar creation, possibly triggered by a nearby supernova explosion and is on the edge of a dark molecular cloud which is an incubator for the birth of new stars.[2]

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.
