PERFUME-YIELDING PLAXTS 573 



Priprioca. (Mespilodaphene (Ocoica) preliosa). A Brazilian 

 tree, found in the forests of Amazonia. "The leaves when 

 bruised give off an agreeable perfume, recalling clove, cinnamon 

 and bergamot at the same time." Considered to be of possible 

 value in perfumery and soap-making. 



Tonka, Tonkin, or Tonga Bean, Known in Venezuela as 

 " Serrapia " (Diptcryx odornla. Leguminosai). A large tree, native 

 of Tropical America, introduced to Peradeniya in 1881. The 

 fruit is an oblong, fibrous pod, containing one almond-shaped 

 black seed. The seeds are fragrant, possessing the odour of 

 new-mown hay, and are used by perfumers for bouquets, as well 

 as in the preparation of sachet powders. They are also employed 

 in scenting soap, snuff, etc., and a "tincture of tonka" is some- 

 times used by pastry cooks and confectioners as a substitute for 

 vanilla. The seeds when dried are subjected to a crystallisation 

 process, being soaked in rum for 24 hours and then slowly dried, when 

 they become covered with white crystals. Tonka beans fluctuate 

 greatly in price, according to supply and demand. According 

 to the Chemist and Druggist the price has varied from 20s. to 7s. 

 per Ib. in less than 12 months. At the time of writing, it is 

 quoted at 7s. per Ib. 



Tuberose (Poliaiithes tuber osa. Liliaceae). A tuberous her- 

 baceous plant, much cultivated in the South of France for the 

 extraction of perfume from its powerfully scented flowers. The 

 plant grows and flowers freely at medium and high elevations, 

 in Ceylon. 



Ylang-ylang, or Ilang-ilang; " Wana-Sapti " S. (Canangn 

 Oifortitn. Anonaceae). A large, quick-growing tree, 60 to 80 feet 

 high, native of the Philippines, Java, etc. The large greenish- 

 yellow flowers are strongly scented, and yield by distillation 

 the popular scent " ylang-ylang " or "Hang-Hang." A full-grown 

 tree may be considered to yield 100 Ib. to 120 Ib. of fresh 

 flowers during its flowering season. From 150 to 200 Ib. of 

 flowers produce about 1 Ib. of the essence, the collection and 

 distillation of which is said to form an important minor industry in the 

 Philippines. Here it is estimated that an acre planted with 

 150 trees may give 3,250 Ib. of flowers, yielding about 16 Ib. of 

 essence. The main supply, however, is from uncultivated trees. 

 The Natives collect and sell the flowers from these for 2il. per Ib. 

 The annual export of ylang-ilang oil from the Philippines is now 

 valued at about 20.000.
