L'Abbe Provancher. Whether he considers it introduced or not I 

 am unable to say, but I should most certainly judge that it is. 



3. Asimina triloba, Dunal, (American Papaw) Rich low 

 woods near the railway below Queenston Heights ; very abundant 

 on Pt. Pelee and in the townships bordering Lake Erie between that 

 point and Amherstburgh ; doubtless not rare along Lake Erie but 

 not reported (Macoun) 



4. Nehimbium lutetim, Willd., (Water Chinquepin) Reported as 

 found in the Detroit River, at the entrance from Lake Erie to the 

 Welland Canal, and near Burnham's Island in Grand River, a few 

 miles from Dunnville, Ont. 



5. Corydalis flavula, D C, (Yellow Corydalis) Abundant around 

 the stone quarry on the north end of Pelee Island, and on Pt. Pelee 

 (Macoun and Burgess) Pt. Abino on Lake Erie (Day) 



6. Sisymbrium Thaliana, Gaud. Pt. Abino, Lake Erie. This is 

 our only recorded station, but Mr. Day, who discovered it, says it is 

 abundant and he thinks indigenous. 



7. Viola fiedata, L., (Bird-foot Violet) The sole known locality 

 we have for this very handsome species is Tp. of Charlotteville, 

 Norfolk County, Ont., where it is very abundant in open sandy soil 

 (Burgess) My specimens exhibit both the type and the var. 

 bicolor of Pursh. All other recorded references to this species refer 

 to Viola delphinifolia of Nutt., which is common on the western 

 prairies.

 of Gray's Manual, is recorded only from damp woods near Amherst- 

 burgh, Ont. (Macoun)
