Cedrene is a sesquiterpene found in the essential oil of cedar. The two isomers present in the oil are (−)-α-cedrene[3][4] and (+)-β-cedrene,[5] which differ in the position of a double bond.

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.
