This hybrid was first described by Dr. Greene" as F. 

 melissaefolia from specimens collected in 1902 by Mr. L. W. 

 Watson on Prince Edward Island. Its hybrid nature was, 

 however, later recognized by Dr. Brainerd, who also states that 

 plants belonging to the same combination, have been collected 

 by Dr. J. Fletcher at St. Stephen, "N.B."
