184 SPECIES OF THE GENUS MELILOTUS—LAWSON. 
ballast hills there, where he says the Melilotus is of compara 
tively recent introduction, and they all prove to belong to M. 
officinalis, Desr. That species may thus be regarded as an 
established plant at Windsor, Nova Scotia, Quebec and Mon- 
treal, and as “casual” or imperfectly naturalized at Pictou. 
At all of the stations where it is now permanently natural- 
ized, it probably owed its origin to the early French set- 
tlers. It is the species described in Vaillant’s Flora Parisi- 
ensis, and other French Floras of last century, and seems to 
have followed the movements of the French people. As regards 
the plants reported from New Brunswick, Ottawa, Belleville, 
Toronto, and London, Ont., they may or may not be referable 
here.
