being so clearly within the geographic limits of the Atlantic 

 type, although so little dispersed within them. The 

 Rev. W. R. Crotch wi-ites to Mr. Dennes, with the date of 

 October, 1847, that " the Lobelia urens is fast disappear- 

 ing : they are enclosing the common where I gathered it 

 before."

Native. Lacustral. This plant might have been referred 

 to the Inferarctic zone, probably, with almost as much 

 correctness as to the Inferagrarian. It ascends to Loch 

 Callater, in Aberdeenshire, and to Loch Brandy, in Forfar- 

 shire, — situate at the extreme limit of the agrarian region, 

 if not rather within the lower arctic zone. On the other 

 hand, the localities in Salop and Glamorgan can bai-ely be 

 held to give the species a local habitation in the lower 

 agrarian zone. Reported from 26 counties ; but I cannot 

 confidently raise the estimated census to the next higher 

 degree, or that of 30.
