Fragments of this ubiquitous species are fairly common at Rich- 
mond, the one figured being the most definite. It indicates a some- 
what more orbicular leaf than the majority of leaves of this species 
but may be compared with several Greenland leaves which Heer 
identifies as Planera ungeri.t | ‘The marginal teeth and venation are 
identical with those of more complete specimens from European 
Tertiary localities and the implied environmental conditions were 
also most suitable. ‘There is some resemblance to the Mascall species 
Betula ? dayana of Knowlton? and also to the Tortonian Betula 
weissit Heer3 of Europe. 
Planera ungert has a recorded range from the Eocene into the 
Pleistocene and a distribution from Manchuria and Japan through 
Asia and Europe to Colorado and Oregon, occurring also in Green- 
land and Iceland. It is quite pos- 
sible that more ‘than one species 
may be included under this name 
but if such is the case their proper 
segregation is still a task for the 
future.

Leaves apparently cordate in 
outline, about 5 to 6cm. long by 
scm. in greatest width, acuminate, 
entire. Venation palmate, the lateral 
primaries of somewhat less caliber 
than the midrib, from which they 
diverge at an acute angle (about 30°) at or near its base. The 
midrib gives off three pairs of secondaries above the lateral primaries
