THE LOWER BLAIRMORE FLORA 
As stated in a preceding paragraph, the Blairmore floras are of very 
great interest, for without any apparent physical break this thick series of 
prevailingly coarse continental deposits contains two distinct floras — that 
of the Lower Blairmore being overwhelmingly of Lower Cretaceous affini- 
ties, and that of the Upper Blairmore, which is discussed in a succeeding 
chapter, being as distinctly Upper Cretaceous in age. Hence in the 
Crowsnest Pass region of Alberta there is a continuous sedimentary record 
from Lower to Upper Cretaceous, and it is much to be hoped that more 
extensive collections and better preserved material may subsequently 
throw additional light on this important stage of palseobotanical history. 
The present collections from the Lower Blairmore have yielded twenty- 
eight different species. These include an interesting representative of the 
liverworts (Marchantites), four so-called species of the genus Sagenopteris, 
believed to represent an extinct genus and order of the Hydropterideae; 
eight additional members of the fern phylum; four cyeadophytes; eleven 
coniferophytes; and one dicotyledon. This flora is especially character- 
ized by the Marchantites, Sagenopteris, species of Cladophlebis, Dioonites
