The Post of Comoros issued the stamp series of aromatic plants on October 9, 2003 . The issue comprises of two postage stamps depicted Ylang-Ylang (Cananga odorata ), and Vanille (Vanilla planifolia).
Ylang-Ylang or Cananga odorata, kenanga (Indonesian), fragrant cananga, Macassar-oil plant is a tree valued for its perfume. The essential oil derived from the flowers is used in aromatherapy.
Cananga odorata is a fast-growing tree of the custard-apple family, Annonaceae and attains an average height of 12 m . It grows in full or partial sun, and prefers the acidic soils of its native rainforest habitat.
The evergreen leaves are smooth and glossy, oval, pointed, with wavy margins, and 13–20 cm long. The flower is drooping, long-stalked, with six narrow, greenish-yellow (rarely pink) petals, rather like a sea star in appearance, and yields a highly fragrant essential oil.
