and characteristic, and they seem to leave no doubt as to the identity 
of the species. 
This species was originally obtained from the Fort Union Group 
at Seven Mile Creek, Montana, and described by Ward. More recently 
it has been found in the Miocene of the Similkameen Valley as 
described by Sir William Dawson.

Eocene of the Red Deer River (Paskapoo Series), N.W.T. 
This very familiar and widely distributed specimen of poplar 
appears in the Eocene from the Red Deer River, and in the material 
now in hand it is seen in the form of one incomplete leaf 5-5 cm. wide 
and 4-5 cm. long. It shows the cordate base, characteristic venation 
and dentate margin, though the latter is largely obliterated.

Eocene of Red Deer River, N.W.T. 
This species is recorded by Newberry from the Fort Union Group 
of Dakota and Montana. It also appears in the Upper Laramie of 
Porcupine Creek, Canada, and is again found in the Eocene of the 
Paskapoo series at Red Deer River, which locality is represented by 
a single fragment of a leaf distinguished by the general form and 
characteristic venation.
