PERFUME-YIELDING PLANTS: 



The extraction of perfume from Howers affords an important 

 industry in some countries, notably in France, where roses, orange 

 blossoms, jasmine, violets, tuberoses, etc., are used by the ton 

 for the purpose. The two principal methods of scent extraction 

 adopted by perfume manufacturers are distillation and maceration 

 or enfleurage, and flowers which are adapted for treatment by 

 either of these methods may be unsuited to the other. The 

 following notes apply to such perfume-yielding plants as may 

 be suitable for cultivation in Ceylon or in similar tropical 

 countries : 



Roses. Cultivated for their scent, about 5,000 rose plants 

 may be planted per acre. After the second year an acre may 

 produce about 6 cwt. of rose petals in the year, these yielding 

 by distillation about 70 ounces of attar of roses, valued at ,20 to 

 30 per Ib. 



Bergamot (Citrus bergatniu. Rutaceae). A kind of bitter 

 orange yielding a valuable perfume from the rind, known as 

 "bergamot." 1,000 fruits will yield about 30 oz. of oil, which 

 when pure is worth from 1 10s. to 2 per Ib. The tree requires 

 much the same treatment as the sweet orange, and in plantations 

 is generally planted about 12 feet apart each way. Another 

 variety of bitter orange called the " Bigardeer" is valued for 

 its flowers, a kilogramme of which yields, on an average, 2 grammes 

 of essence, which is worth, according to quality, from ,10 

 to 18 per Ib. 



Cedrat (Citrus medica. Rutaceae). A highly scented oil 

 obtained from the rind of the citron, worth about 18s. or more
