Under the above name Sir William Dawson described elongated, 
narrow, univeined leaves from several localities in the supposed Kootenay 
of British Columbia. Similar remains were subsequently described and 
figured by Fontaine from both the Lakota and Fuson formations of eastern 
Wyoming. Identical remains are not uncommon in the Upper Blairmore. 
They are always broken and are not certainly referable to the genus Pinus. 
Whatever their nature they appear to be the same objects as those described 
by Dawson and Fontaine. They are not very satisfactory stratigraphic 
items as they are readily confused with small specimens of Oleandra, 
fragments of Czekanowskia, slender stipes of ferns, etc. 
Localities CS5, DA5, and DA6.

Lesquereux, Flora Dakota Group, p. 42, PL 8, figs. 2-4 (1892). 
A single, not very well preserved, leaf from locality CH9 may represent 
this species. It is common in the Atane beds of western Greenland and 
has been recorded from the Dakota sandstone of the United States. It is 
not certainly related to the genus Populus.

A triveined Ficus, which is the most common dicotyledon in the col- 
lections from the Upper Blairmore, appears to be identical with this Atlantic 
Coastal Plain species, which was originally described from material from 
the Raritan formation of New Jersey. In the Coastal Plain this species 
ranges throughout the earlier half of the Upper Cretaceous, but it has 
never been found in the corresponding beds of the west. I have queried
