Brighton — Mr. Macoun. Montreal, abuudant; also, Niagara 

 River — Dr. P. W. Maclagaa. Probably we have more than one 

 form, possibly more than one species. The Montreal and Niagara 

 plants I have not seen. 



Lithospermum arvense, Linn. Adventive from Eiuop An 

 abundant weed in gardens at Kingston, Ont., 16th May, 18b2, 

 in fl., G. L. Montreal— Dr. P. W. Maclagan. In wheat fields, 

 Brighton ; also, Taylor's Hill, Belleville ; common — Mr. Macoun. 

 The plant varies somewhat, being either simple or divaricately 

 branched from a straight red tap-root ; the red root gives out a 

 purple stain to paper in the herbarium. It extends south to 

 Florida. 



Var. a. incanum. Leaves linear, narrow, more or Itss canes, 

 cent. Indian Island, (uninhabited,) Bay of Quinte, Gr. L. I 

 have the same form from Malta. This appears to be the proper 

 form of the plant. 



b. robustum. Leaves linear, lanceolate, pale green, covered 

 with very short setaceous hairs. This is the common weed form. 

 English (Cambridgeshire) and Scotch specimens agree with this. 

 It is larger than the plant from Indian Island.
