The Semper's organ is an anatomical structure, a gland located in the head of some land snails, pulmonate gastropod mollusks.[1]
This organ was named after the German zoologist Carl Gottfried Semper, who first published information about this anatomical structure in 1856.[1][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.
