Latitude 50 — 52. English (?) type of distribution. 



Agrarian region. Inferagrarian zone. 



Descends to the coast level, in the Peninsula. 



Ascends to 50 yards, more or less, in England. 



Range of mean annual temperature 52 — 49. 



Native. Ericetal, Uliginal. Recorded only in the five 

 counties mentioned above, and in Cooper's general list of 

 Metropolitan plants ; the latter being very likely an error. 

 As the Sussex localities would seem to be a little to the 

 northward of the line which bounds the fifty-first degree 

 of latitude, it is necessary to include the next, or fifty- 

 second degree, in its latitudinal range, in conformity with 

 the rule explained on page 60 of the former volume. It 

 seems optional whether this should be considered an ex- 

 ample of the English or of the Atlantic type of distribution.
