I have not stations for Anemone narcissiflora, Turritis patula, 

 T. retrofracta, Llnum perenne^ and Polemoniiim caeruleum, 

 beyond the mere fact of their presence in Canada; but judging 

 by their range in British America, the Lake Superior or Lake 

 Huron region must be the place of their occurrence. 



The shores of Lake Huron, it may be mentioned, are the only 

 recorded stations in Canada for 3Iatricaria inodora, 3Iulgedium 

 pulchellum, Cirsium undulatum, Crepis runcinata, Senecio canus, 

 and Asj)idium Lonchitis. Owen Sound, on the Georgian Bay, is 

 a station for the very rare Scolopendrium officinarum. Hesp>eris 

 matronalis, and Poterium sanguisorha, both garden-plants, are 

 said by Hooker to have been found on the shores of the same 

 lake. The very rare Juncus stygius has also been gathered at the 

 Bruce Mines. 



In addition to the plants enumerated in the above list, there 

 are some which in Canada appear to be confined to this district, 

 but in their range beyond the province cannot be classed as 

 western plants. Such are Sisymhrium canescens, Coreopsis lanceo- 

 lata, and C verticellata (?), which extend into the southern 

 United States. 



There are also a few species met with around the upper lakes, 

 which in the United States flora appear to be exclusively north- 

 western plants, but which re-appear near the north-eastern Cana- 

 dian boundary-line, and doubtless are spread over the intervening 

 space. Parnassia ]jalustris, a species of Upper Micliigan, the 

 Lake Superior region, and north-westward, likewise occurs in 

 Labr.>dor and Newfoundland ; and Artemisia borealis, another
