For the purpose of this work, most of the Southern 

 County Floras have been examined, and for the identification 

 of species and varieties I have mainly relied on ' ' English 

 Botany, ed., J. T. Boswell Syme, Edition III., 1863-72," 

 with its addition of the Cryptogams, 1886 ; and on Hooker's 

 Student's Flora. 



PLAN OF THE FLORA. 



In the arrangement and nomenclature I have followed 

 the 7th ed. of the "London Catalogue" of British Plants, 

 edited by the late H. C. Watson, but have adopted also the 

 8th ed. by Mr. F. J. Hanbury, as to the inclusion of non- 

 natives, differentiating them " by printing in ordinary type, 

 but preceded by an asterisk, the names of such as are 

 thoroughly established and look quite wild, whilst the names 

 of more evident introductions are printed in italics, so that 

 they can be distinguished as aliens at a glance." The 

 necessity of an Appendix as to Casuals, &c., is thus 

 obviated. 



I have prefixed no numbers to the genera and species, 

 since, except for exchange of specimens, they seem to be of 

 little use, and their frequent alterations lead to confusion in 

 the arrangement of herbaria. Every plant, unless followed 

 by the sign ! after the Latin name, has been seen growing in 

 Sussex by me, or verified from reliable herbarium specimens. 

 An A. has been occasionally added to plants observed by 

 myself, by way of distinction. The Sussex plant names are 

 preceded by an S. The terms used to denote frequency, as 

 "com.," " rather com.," or otherwise, refer to the whole of 

 the county and not to particular districts. With respect to 

 supposed extinctions, as Cyclamen hederserolium, Juncus 

 acutus, &c., it has been thought well to retain such, as 

 interesting matter of history.
