Ascends to 150 or 200 yards, in England.

Native. Pratal. The distribution of this plant does not 

 correspond well with any of our types. From the Scottish 

 type it differs by extending more to the southward, and 

 less to the northward ; the plant being, indeed, scarce and 

 quite southern in Scotland ; although prevalent chiefly in 

 the north and west of England. It is thus a link between 

 the English and Scottish types, while its limited area and 

 low census remove it from the British type. 



Sanguisorba media, Linn. 



Area [13]. 



Incognit. Stated to have been found by Mr. George 

 Don, in the west of Scotland ; but some variety of the 

 British species, P. officinalis, would seem to have been 

 mistaken for the American plant.
