swamp subsided. Upon this surface lie the coarse sands shown 

 in the upper half of the photograph. 



The additions to the Pleistocene flora of Virginia are enumer- 

 ated below. Those from below Port Koyal were collected by 

 Dr. L. W. Stephenson, of the U. S. Geological Survey, who has 

 also kindly furnished the two photographs here reproduced.

This riverside and flood-plane species appears to be abundant 

 in the swamp deposits of our southern coastal plain, due doubt- 

 less to its abundance along the rivers which contributed their 

 flotage to these deposits. The present occurrence is based upon 

 leaves from the right bank of the Rappahannock River one and 

 one half miles below Port Royal. 



A number of fragments of leaves, evidently those of some oak 

 but too fragmentary for even tentative specific determination, are 

 contained in the collection from the right bank of the Rappahan- 

 nock River one and one half miles below Port Royal, and unde- 

 terminable acorns occur in the Talbot deposits near the Nomini 

 Cliffs on the south shore of the Potomac.

The characteristic leaves and burrs of this species occur in the 

 Talbot deposits near the Nomini Cliffs. No nuts were found 

 associated with the other remains, but an extended search was 

 not made. This species was one of the commonest trees of the 

 Pleistocene if we may judge from its abundant remains at a 

 large number of localities in Pennsylvania. Maryland. Virginia, 

 West Virginia, Tennessee, North Carolina and Alabama.
