Galinsoga parviflora Cav. is an immigrant from Tropical America 

 which we have already recorded in the "Naturaliste Canadien (XXXVII: 

 ^2; XXXVII: 130). It is now a pest everywhere in the gardens around 

 Montreal. It has even invaded the edge of sidewalks in the city. 



Potentilla intermedia L., is forming extensive patches in lawns at 

 Outremont, Island of Montreal. It is an introduction from Europe via 

 the Northeastern States, but like most of the Rosaceae, it is not liable to 

 do much damage. 



Tragopogon pratensis L., the wild salsify is thoroughly naturalized 

 around Mount St. Hilaire, one of the Monteregian trap hills. There it 

 thrives in orchards and along roadsides. We do not know it out of this 

 limited area. 



Vinca minor L., is another introduction in the orchards of St. Hilaire. 

 It is propagated by runners, the flowers being, as can be expected, rather 

 scanty. 



Inula Helefiium L., this giant weed, common in Ontario, has maintain- 

 ed colonies for several years around Longueuil. 



Serapias Helleborine L., represents the unique feature of a naturalized 

 Orchidaceae in this country. It has become exceedingly abundant on 

 and around Mount Royal. The probable origin is cultivation in very 

 early times on account of supposed medicinal properties. We can believe 

 with some amount of certainty that it is a relic of primitive gardening on 

 the Island, and that it has been brought by the first French settlers. Lysi- 

 machia punctata L., reported for a long time to occur around Annapolis 

 (N.S.), and now naturalized in our Province as far as Temiscouata County, 

 has probably a similar origin. 



Hieracium Pilosella L. The last but not the least. It is really to 

 be wondered that official agriculturists in this country do not seem to 

 realize that this Hawkweed is steadily invading our Province, and will 

 become here, as it is in the Maritime Provinces, a most noxious weed. 



We have seen it in Temiscouata, though rather sparingly, during the 

 summer of 1913; but, last summer, we were amazed to see it checking all 

 other vegetation in some pastures at St. Raymond Co., Portneuf, in the 

 heart of the Laurentide district. If we add that we are aware it is doing
