 MUSCI (Mosses) 



There are 567 species and sub-species of true mosses in Dixon's 2nd edition Handbook of 

 British Mosses. The appended list contains 217 species and sub-species found in Leicestershire 

 and includes 35 additions to the one in the Flora of 1886. Nottinghamshire has 207 known 

 species and sub-species, so that as regards ' native ' flowering plants and mosses the number is 

 remarkably similar, a difference numerically of 8 species only. Lincolnshire is known to have 

 196 species and sub-species of mosses; Northants 225. Warwickshire is known to have some 

 20 or more species than Leicestershire ; possibly this excess is due to more thorough search. Derby- 

 shire is far richer in mosses, and has had much more attention from bryologists than any of the 

 other counties mentioned. There are 40 Warnstorfian species of Sphagnum in Britain, 9 in 

 Leicestershire, 10 in Lincolnshire, n in Nottinghamshire, 4 only in Northamptonshire; Derby- 

 shire has many more, and further north-westwards there are 30 in Lancashire, a similar number
