Cratcegus tranquiUensis n. sp. 



In collections from the Tranquille river, as also from the Horsefly, single specimens of a 

 leaf were found. These were directly comparable with recent forms of leaves of more than 

 one species of Cratcegus to which they undoubtedly belong. They are represented by figure 8 

 and answer to the following description : — 



I'n;. 8. <'rattnlii» (niiH/ltiflrnsia 11. ^11. 



Li-Lif from thf Hor.seHy Kiver. x 1/1. 



Leaf short-petioled ; 35 mm. long, 32 mm. wide, broadlj' obovate with a somewhat wedge 

 shaped base ; veins strongly defined ; margin rather finely and irregularly dentate ; apex 

 broad, rounded, in the specimen somewhat emarginate by breakage. 



Several species of Cratcegus are known in the United States, but with one exception 

 they are all Cretaceous. There is no record of the genus in Canada other than the one now 

 made. Had the fruit and leaves occurred in the same beds, there would have been little 

 reason for regarding them as distinct species, but their isolation in somewhat widel}' separated 

 beds makes such a conclusion unsafe.

Ill the report of the Geological Survey of Canada for 1873-74, Dr. G. M. Dawson records 



the occurrence in the Edmonton coal beds of specimens of wood which he refers to the genus
