Ebonol is a synthetic material whose name derives from its similarity in appearance, hardness, and stability to ebony wood. Ebonol is used as a substitute for ebony in the construction of stringed and woodwind instruments (specifically clarinets). The material is particularly well suited for the fingerboards of fretless bass.
Ebonol is technically known as "XXX Paper Phenolic" and is a high-pressure laminate made from layers of black paper and phenolic resin. [citation needed]
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.
