BOTANY 



chalk formation are as well represented as they are in the South Downs of Sussex. A list of chc 

 species found in Kent was published by the writer of this article in the Journal of Botany, 

 1888, and a number of species that had not then been discovered were pointed out as litely to 

 occur. Most of these were subsequently detected in the county and an additional list was 

 published in the same Journal in 1901, pp. 179, 227. 



But in the meanwhile the nomenclature of mosses had been altered, and it is consequently 

 necessary to give the list anew in order to bring it up to date, more especially as several more 

 species have been detected since 1 90 1. This increase of species has been largely due to the 

 investigations of the Rt. Hon. Mr. Justice Stirling of Goudhurst, Mr. W. E. Nicholson of 

 Lewes, and Mr. E. S. Salmon of Reigate, who have explored the district around Goudhurst, 

 to Mr. L. J. Cocks of Bromley, and to Mr. A. W. Hudson of Cranbrook, and in the case of 

 Sphagna to Mr. E. C. Horrell of Chelmsford. 



The classification and nomenclature that have been followed in this list are those of the 

 second edition of the Student's Handbook of British Mosses, by H. N. Dixon, M.A., and H. G. 

 Jameson, M.A., published in 1904. The species rare in the county are indicated by an 

 asterisk. Those which as yet have been found only in Kent are Catharinea tenella in fruit 

 and Ephemerum stellatum. A few species are extremely rare in other counties, e.g. Nanomi- 

 trium tenerum and Pottia ccespitosa, fVeissia sterilis, W. crispata and W. multicapsularis. The 

 list includes 283 species, exclusive of numerous varieties.
