Among the more well known tea tree oils, is Niaouli Oil which is steam distilled in New Caledoniafrom the leaves of Melaleuca Viridiflora. The tree grows wild and in such abundance that cultivation is not at all necessary. The New Caledonian tree is a native of Australia and it exists in several physiological forms. The Melaleuca Viridiflora which yields Niaouli Oil is usually considered as a typical form of the tree, while the varieties which still grow in Australia yield oils of entirely different composition. The best known of these Australian oils is the Melaleuca Viridiflora, variety "A". The essential oil from this tree contains significant amounts of Nerolidol and the oil has at one time been considered as a possible source for isolation of this interesting sesquiterpene alcohol.
