South limit in Dorset, Sussex, Kent. 



North limit in Shetland and Orkney. 



Estimate of provinces 5. Estimate of counties 5. 



Latitude 50 — 61. Local type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the south coast of England. 



Ascends, on the coast level, to Shetland. 



Range of mean annual temperature 51 — 47. 



Native. Littoral. Local and peculiar in its distribu- 

 tion ; occurring on the coasts of Dorset, Sussex, Kent, 

 Suffolk and Shetland. Those of Lincoln and Orkney are 

 reported on old and unsupported authority; but neither ol 

 them appears any-wise an improbable habitat. The beach 

 near Penzance, in Cornwall, and that of Sandown, in the 

 Isle of Wight, are also on record ; and though these places 

 are likely enough, the plant is no longer found there. 

 Apart from the localities of Orkney and Shetland, the dis- 

 tribution would have appeared that of the Germanic type, 

 that is, looking solely to England.
