and these are apparently camptodrome. ‘Tertiaries numerous, but 
slightly curved, transverse. Lateral primaries giving off externally 
three or four nearly straight branches. 
The fossils, like the recent species of Ficus, are very numerous and 
range from the Cretaceous upward. ‘The present species is based on 
the single imperfect specimen figured, which seems to be referable 
to this genus although the allied genus Celtis suggested itself. A rather 
similar form from Florissant, Colorado, is doubtfully referred by — 
Cockerell to the genus Morus.' The entire margin is a more constant 
character in Ficus than it is in either of these other genera and the 
venation is closer to that of the leaves usually referred to Ficus, which 
facts have largely determined the present identification.

Two fragments of Platanus leaves showing neither the outline nor 
margin, but containing parts of two secondaries with the characteristic 
tertiary venation of this genus, were found at Richmond. ‘Their 
specific affinity cannot be made out with certainty, and they are referred 
to this species with some hesitation. The tentative determination 
‘is made on the ground of the abundance of this species elsewhere 
at this time, and also immediately before and afterward. As far as 
the specimens will permit of comparison they agree perfectly with 
this form. :
