12. CARYOPHYLLACE^. 207 



Estimate of provinces 17. Estimate of counties 75. 



Latitude 50 — 58. British type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 300 or 350 yards, in East Highlands. 



Range of mean annual temperature 52 — 43. 



Native. Agrestal and Septal. The white and red 

 flowered plants, associated together under the name of L. 

 dioica, appear in several lists only under their Linnean 

 name. For this reason, it is often uncertain whether only 

 one or both are intended by the name ' dioica ' ; and in the 

 absence of any explanation, I have assumed this latter 

 name to mean only the red- flowered L. diurna. The white- 

 flowered L. vespertina is probably most plentiful in the 

 south and east of England ; and it would appear to be 

 pretty frequent in Scotland also, by the local floras and 

 lists ; though beyond the Grampians it may be only a 

 ' colonist,' through agriculture. 



165. Lychnis Githago, Lam. 



Area, general ? 



South limit in Cornwall, Isle of Wight, Kent. 



North limit in Orkney, Ross-shire, Argyleshire. 



Estimate of provinces 18. Estimate of counties 80. 



Latitude 50 — 60. British type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 52 — 46. 



Colonist. Agrestal. There is much probability that 

 this species of Lychnis or Agrostemma is one of our intro- 

 duced plants, which would again disappear from Britain, if
