PREFACE 



I TAKE over the task of continuing the work of my 

 friend, the late Mr. H. Rackham, with many fears 

 lest my efFort prove an unworthy sequeL 



A complete index of plants will be found at the end 

 of Volume VII. To identify each plant or tree as it 

 occurs would have involved many repetitions and 

 cross-references, but a few identifications have been 

 inserted in the text and notes where they seemed 

 specially needed.
