IV. Comparison with Adjacent Counties.*— Tho following is a list of 

 those species — native and naturalised — recorded in one or more, but not in 

 all, of the group of five counties of which Middlesex forms the centre. 

 They are numbered consecutively ; a ? implies doubt ; a signifies that the 

 species is a mere casual. Many maritime species are restricted to Essex ; 

 the fiora of Bucks is as yet imperfectly known. 



* A very small portion of Kent may be considered ' adjacent ' to the Isle of Dogs, from 

 which it is separated by the Thnmes. To have included the flora of Kent in the following 

 comparison, however, would have extended it very considerably, as that county possesses 

 many additional species.
