The following Table therefore will show at a glance how the 

 plants of the Lakes are spread through the rest of Britain, and 

 how the Lake flora stands in comparison with that of the 

 north-eastern counties : — 



Broadly speaking, leaving out the local species, we may 

 reduce the other types to three, viz. (1.) General (British) ; 

 (2.) Austral (English + Germanic + Atlantic) ; and (3.) Boreal 

 (Scottish + Highland + Intermediate) ; and say for Britain as a 

 whole, 532 species are general in their distribution, 606 

 southern, and 238 northern, and that out of the southern 

 species 231, and out of the northern species 125, grow in the 

 Lake district.
