THE WILLOWS 27 



The most convenient arrangement of the ninety or 

 more forms of Willow which occur in our islands 

 seems to be that of Du Mortier, as modified in Pro- 

 fessor Babington's " Manual of British Botany." 

 According to this system the genus is divided into 

 three sections, Vitisalix, Caprisa'lix, and Chame'lyx, 

 which, with their sub-sections, series, and sub-series > 

 run as follow, a few synonyms having been added for 

 the use of students accustomed to other books : 



Section I. Vitisalix. 

 Sub-section i. Ly'cus ( = Pentan'drse). (Bay- 

 leaved Willows.)
