the identification since all of the triveined ovate leaves of Ficus are very 
much alike, and these Upper Blairmore leaves, which are quite variable, 
as may be seen from the accompanying illustrations, are not preserved 
sufficiently well to show the details of venation. 
They occur at localities CS4, CSS, CH9.

A single fragment of a leaf from locality CH9 is referred tentatively to 
this species. The type was from the Dakota sandstone of Nebraska and 
the species was subsequently identified by Heer from the Atane beds of 
western Greenland, It occurs also in the Raritan formation of the Atlantic 
Coastal Plain. 
It is a somewhat variable form and the fragment from the Upper 
Blairmore is typical in so far as comparisons are possible. 
Genus, menisfekmites Lesquereux 
Menispermites reniformis Dawson (?)

Menispermites reniformis Dawson, Trans. Roy. Soc., Canada, vol. 1, sec. 4, 
p. 23, Pl. 4, fig. 12 (1883). 
Two or three fragments of a leaf of a type commonly referred to the 
genus Menispermites are present in the collections from the Upper Blair- 
more and probably represent this species which was very incompletely 
described and inaccurately figured by Sir William Dawson from specimens 
collected at Coal brook, British Columbia. 
They show considerable resemblance to Menispermites borealis Heer 
of the Atane beds of western Greenland and the Raritan formation in New 
Jersey, but in the absence of more complete material their status in the 
Upper Blairmore remains somewhat uncertain. Attention should be 
called to the possibility that these so-called Menispermites may represent 
the family Trochodendraceae. 
Localities CH9 and DA5.
