ABSTRACT
In the Lavandula genus, there are two plant species and one hybrid which produce aromatic oils of interest to the perfumery industry. In all three groups there are many thousands of different genotypes yielding individual oils which differ widely in commercial value. The oil is secreted in small globular glands between the ribs of the flowers’ hairy calices (Figure 10.1). Traces of immature oil may also be found elsewhere in the plant material but if the flowers are ripe these traces do not affect the perfume; but with under-ripe flowers they may contribute to a ‘green’ note in the oil.
