The Genus Lavandula


This classification follows the latest revision of the genus by Tim Upson and Susyn Andrews ( The Genus Lavandula 2004 published by The Royal Botanic Gardens, Kew ISBN 1 84246 010 2). The most obvious change is the erection of three new subgenera. The previous six sections are retained and two new ones added, making eight in all. Some new species are recognised, bringing the total number of wild species to 39.
