PLEISTOCENE FLORA OF NORTH CAROLINA 343 
QUERCUS PLATANOIDES (Lam.) Sudw. 
Several leaf specimens from station 850. It is, of course possible 
—I might say, probable—that the leaves of this and the preceding 
represent the variable leaves of their common Pleistocene ancestor, 
not yet differentiated into dry and moisture loving forms. 
QUERCUS PRINOIDES Willd. 
Leaves which apparently represent this species occur at station 850, 
although it is impossible to determine their exact relation to the two 
preceding forms. 
Uimus ALaTa Michx. 
Several leaves of this modern southern type were found at station 
850. Two species of Ulmus are known from the Sunderland of 
Maryland; Ulmus betuloides Hollick, possibly representing the 
modern Ulmus americana L., and Ulmus pseudo-racemosa Hollick, 
representing the modern Ulmus racemosa Thomas. The latter also 
occurs at Morgantown, W. Va., and in the Don River deposits of 
Canada, where it is associated with Ulmus americana. 
PLANERA AQUATICA (Walt.) J. F. Gmelin. 
This southern type in the modern flora is represented by two or 
three rather unsatisfactorily determined leaves from station 850. 
The related, if not identical Planera ungeri Ettings is recorded from 
the Sunderland of Maryland. 
Ranales 
BERBERIS SP. 
A single leaf, apparently a barberry, but not specifically determin- 
able, was found at station 850.

The sweet or red gum is sparingly represented at station 850 by 
two or three fragmentary leaves and one flattened fruit-head. Pre- 
viously recorded from Morgantown, W. Va., by Knowlton, and from 
Bridgeton, N. J., by Lesquereux and Hollick. I should expect this
