Native. Viatical, Agrestal, &c. The usual situations in 

 which this plant occurs, as by the side of fields or path- 

 ways and on ditch or hedge banks, may be held to place 

 it intermediate between the agrestal and viatical, or the 

 agrestal and septal plants. I am aware of only two habi- 

 tats northward of Durham ; one, in the vicinity of Berwick- 

 on-Tweed (Thompson, &c.) ; and the other, by the " side 

 of a path between Roslin and Lasswade, Edinburgh," 

 where Dr. Graham reported (Excurs. 1835) that it had 

 been found by Mr. James Macauley, but probably intro- 

 duced to the spot. Is it indigenous near Berwick-on- 

 Tweed ?
