Undecylic acid (systematically named undecanoic acid) is a carboxylic acid with chemical formula CH3(CH2)9COOH. It is often used as an antifungal agent, to treat ringworm and athlete's foot, for example.[1] Like decanoic acid, it has a distinctive, unpleasant odor.

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.
