This species originally described by Forbes as Alnites, but 
transferred to Corylus by Heer, is represented in the material from 
the Red Deer River by two leaves, one of which is 7-5 X 11-5 cm. and 
shows the characteristic base, venation and to a large extent, also the 
margin. The other fragment of about half the size of the first, has 
had a large portion of its margin removed. Otherwise it answers to 
the characters of the species. 
In his Flora of Spitzbergen, Heer describes many fragments of 
leaves which he refers to this species, but the fragmentary nature of 
the material leaves an element of doubt as to the identification. From 
the same locality — Cape Staratschin — he also describes several fruit- 
like bodies considered as possibly the fruit of this species. In his 
Miocene Flora of Northern Canada, Heer also records and figures the 
same species, the fragments of leaves shown, exhibiting in their well 
preserved venation, characteristic features. 
Lesquereux has recorded the occurrence of this species in the 
Tertiary of the Washiki Group at Carbon Station, Wyoming. He 
further draws attention to the fact that at that time no specimens 
had been seen from the Upper Miocene of the Green River and the 
Parks, and that such material as has been obtained from the Lower 
Lignitic, represents indistinct and scarcely determinable specimens. 
In his Cretaceous and Tertiary Floras, however, he records its occur- 
rence in the Miocene of the Bad Lands, and gives an excellent figure 
of a nearly complete leaf. The best diagnosis of this abundant and 
widespread species, as illustrated by a very characteristic and nearly 
complete specimen, and that which is chiefly relied upon in the present 
determination, is given by Newberry in the Later Extinct Floras of 
North America, where material from the Fort Union Group is 
described.
