Cananga odorata, known as the cananga tree, is a tropical tree that is native to India, through parts of Indochina, Malaysia, the Philippines and Indonesia, to Queensland, Australia. It is valued for the perfume extracted from its flowers, called ylang-ylang /ˈiːlæŋ ˈiːlæŋ/ EE-lang-EE-lang (a name also sometimes used for the tree itself), which is an essential oil used in aromatherapy. The tree is also called the fragrant cananga, Macassar-oil plant, or perfume tree. Its traditional Polynesian names include Mataʻoi (Cook Islands), Mohokoi (Tonga), Mosoʻoi (Samoa), Motoʻoi (Hawaii), and Mokosoi, Mokasoi or Mokohoi (Fiji).
