THE BOG-MOSSES (SPHAGNACE^)) OF ESSEX : 



A CONTRIBUTION TO THE FLORA 



OF THE COUNTY. 



Read by FRED. J. CHITTENDEN, County Technical Laboratories, Chelmsford. 



THE present paper is an attempt to collect the scattered 

 records of the occurrence of the Bog-Mosses in Essex, to 

 bring the nomenclature into line with more recently published 

 lists, to define the limits of their distribution at the present da\> 

 and to correlate their distribution with the geological formation 

 of the county. 



In the Victoria History of Essex the following remark occurs 

 respecting the Sphagnaceae or Bog-mosses: " Comparatively few 

 species of Sphagna are recorded, but the list of species of this 

 genus will probably be largely increased by further investi- 

 gation."
