Lobelia puberula. Andropogon argenteus. 



L. spicata. Allosorus atropurpureus. 



Two or three of the species above enumerated are stated by 

 Prof. Gray to be common in the northern United States, but I 

 am not aware that they have been observed in Canada in locaUties 

 beyond the Erie district. 



III. Superior Type. 



It is upon the shores of Lakes Huron and Superior, especially 

 of the latter, that the vegetation begins to partake somewhat of 

 the character of that west of the Red River. Such plants as 

 Linuin perenne, Lonicera involucrata, Crepis runcinata, and 

 Coriosjyenjium liyssopifolium do not fail to remind us of the 

 country watered by the Saskatchewan, and of the adjacent Amer- 

 ican territories. Not many of these far-western species have as 

 yet been met with ; nevertheless, the resemblance is sufficiently 

 marked to be noticeable. Future collectors will, there is little 

 doubt, not only increase the number of these species already 

 detected, but also add to the list of sub-alpine plants whose 

 occurrence has been noted on the north shore of Lake Superior. 



Were these western plants absent, the flora of the east and north 

 shores of Lake Superior would much resemble that of the section 

 of country along the south shore of the St. Lawrence from about 

 Quebec downwards to the Gulf. The Cupuliferse find their limits 

 upon the eastern coasts of the lake, whilst Tilia Americana is 

 entirely absent. Fraxinus sambuci/olia is still met with, but 

 F. Americana does not penetrate much beyond the upper shores 

 of Lake Huron. 



Among the western species at present known to difi'use them- 

 selves as far as our borders, are included the following plants: 

 Anemone narcissiflora. Crepis runcinata. 



Ranunculus abortivus, Mulgedium pulcbellum. 



var. micranthus. Tanacetum Huronense.
