Lobelia iujlata, L., a well distributed plant of both Provinces, 

 occurs in grain fields in the Province of Quebec, iind is thought 

 to be the cause of some cases which Lave lately occurred of 

 poisoning among cattle. 



Jlcdwma pn/ry loidcs, Pers. and 77. Iilaphla, Pursh — neither of 

 which seems to range into the districts north of Lakes Huron 

 and Superior and into the Province of Quebec — both have, Mr. 

 Miicoun inioruis me, spreading habits at Belleville. 



Vcfhijia hasfafa, L. is a l're({uent intruder on road-sides and 

 in neglected fields. In the indigenous state it is common from 

 the Manitoulin I>lands to the ueighbourlioud of Quebec. 



V. iirtici/a/id, L. This species occurs in similar situations to 

 V. hdstatit. and has a nearly analogous range. 



Vcfoniai pcrcijrliia, L. This is a woU-knuwn grass plant, 

 occurring on lawns, in parks and elsewhere. Its recorded range 

 is from Luke Erie to the vicinity of Quebec. 



lTrticagriir.il is, Ait, Macoun remarks, has an introduced habit 

 at Belleville. From Lake Superior to Auticosti this plant has 

 been everywhere met with. 



Fuli/yniiinn PcnHsijlvaiiiaim, L. In wet fields, road-sides, and 

 railway ditches, this, and perhaps one or two more i'olygonums 

 arc often found. 1\ I'ciiiini/lviinicifiii is known to range from 

 the Manitoulin Islands to below Montreal, 



Acalijpha Virgiitica, L., is a familiar weed in some places. The 

 species is distributed from the Erie district to about the City of 

 Quebec. 



Euphorbia macula ta, L., is a known road-side plant, and is 

 possibly an introductiun from the United States. It ranges over 

 a considerable portion of Ontario. 



U. commutata, Engcl., has been noticed at Shannonville, Ont., 

 by Macoun, who remarks its introduced like appearance. 



tSulix liicida, Muhl., is very common in the ditches and moist 

 grounds on the sides of railway track... It is abundant through- 

 out the two Provinces. 



Panicum capillarc, L. 



When the Provinces were originally settled by the ancestors of 

 the present French population, we can believe that many of the 

 weeds of France found a home nere. Immigration during suc- 

 ceeding years from the same country, and from Great Britain and 

 Germany, not only repeated the introduction of many of these 

 weeds, but largely swelled the number of introduced species.
