Native. Paludal. Not a common plant ; although suf- 

 ficiently frequent in the Floras, to have been classed above 

 the rarer species. It is certainly a very scarce plant in the 

 northern provinces ; and hence I have not ventured to ad- 

 mit the Orkney Isles within its area, although reported as 

 "common" there, on so good an authority as Dr. Neill. 

 Mr. Croall collected it " near Old Montrose " in the East 

 Highlands. These two are my only authorities for the ex- 

 istence of this species northward of the Forth.
