INTRODUCTION. XVli. 



H. Cooper, in a supplement, appended good lists of the less 

 common plants, especially as regards their geologic and 

 climatic distribution. In 1875 Mr. W. B. Hemsley, who had 

 previously contributed several papers on the subject to the 

 " Journal of Botany," published in an appendix " An 

 outline of the Flora of Sussex" of great value, as showing 

 the occurrence of species in the various districts; and in 

 1883 appeared "Watson's Topographical Botany," which 

 enumerates the plants of E. and W. Sussex. These are the 

 chief works relating to the Botany of the county in general. 

 The district Floras have already been referred to, and as 

 supplementary to these, much information occurs in various 

 Botanical periodicals, and in the Reports of the proceedings 

 of the several Sussex Natural History Societies. 



BARE SPECIES PECULIAR TO CERTAIN DISTRICTS.

Phyteuma spicatum is perhaps the only British plant 

 peculiar to Sussex. Scirpus carinatus and S. triqueter 

 appear to be confined to the banks of the Arun. Some of 

 the above species may probably hereafter be met with in 

 other districts. An analysis of the Flora, as regards the 

 geographical distribution of species in the county, would 

 occupy more space than can here be given. Of the 1680 

 species in the " London Cat.," 7th ed., 1135, with 12
