PREFACE. 



THE present work is based upon Hanbury and Marshall's Flora of 

 Kent, published in 1899, and covers Districts 1 and 2 of that book. 



District 1 extends from the West Kent county border to a line on 

 the East drawn through Erith, Crayford, Bexley, Orpington and 

 Keston. District 2 extends from this line on the west, to a line 

 on the east, drawn through Rochester and Snodland, and bounded 

 on the south by the North Downs ; this district includes the sub- 

 maritime area extending from the Isle of Grain to Gravesend. 



The attention of those who use this Flora is drawn to the following 

 features : 



(1) The nomenclature followed is that of the British Museum 

 catalogue, 1907, compiled by Dr. A. B. Rendle and Mr. J. Britten, 

 of the Natural History Museum, Kensington, in accordance with 

 the International Rules of Botanical Nomenclature adopted by the 

 Botanical Congress at Vienna in 1905. These rules insist on the 

 adoption of the earliest specific name of a plant, no matter under 

 what genus it was first described. A detailed account of the altera- 

 tions will be found in the Journal of Botany for March, 1907. 

 Generally speaking, the nomenclature does not differ much from 

 that given in the ninth Edition of Babington's Manual, published 

 in 1904. 



(2)' The classification and arrangement of the Natural Orders is 

 that? followed by Engler and Prantl in the Pftanzenfamilien 

 (18891905).
