86. GRAMINA. 145 



Descends to the sea level, in the Peninsula. 



Ascends, at the sea level, to Trent province. 



Range of mean annual temperature 52 — 49. 



Native. Littoral. The counties in which this plant is 

 known, being few, are all mentioned above in the line of 

 its limits ; the Isle of Wight being part of the same 

 county with mainland Hants, on the coast of which latter 

 it also occurs. Although extending westward to Devon, 

 on the south coast of England, it is otherwise so decidedly 

 a plant of the eastern and south eastern coasts, that no 

 hesitation can be felt about its assignment to the Germa- 

 nic or eastern type of distribution. But if it had been 

 known to occur on the Welsh coast likewise, the English 

 or southern type would have been named instead.
