ceedingly common throughout the Pleistocene of Europe from 

 Sweden and Finland to Italy where they are generally referred 

 to under the name of Brasenia purpurea. A fairly complete 

 discussion of them has been given by Stoller.* 



In America the water shield is widely distributed in appropriate 

 situations from Canada to Central America, and in the Atlantic 

 and Pacific regions, and what systematists consider the same 

 species occurs in similar environments on all of the continents 

 except Europe, where it is no longer native. 



This small florule is interesting in several ways : First, because 

 of its occurrence in the center of a region of many and extensive 

 clay workings of lower Eocene age, it being the only Pleistocene 

 clay recognized along this upland ridge; Second, in showing no 

 traces of oaks, beech or of the bald cypress which are so common 

 in the Pleistocene deposits of southeastern North America; 

 Third, in that the plants preserved are those of dry pine land 

 {Pinus taeda), associated with pond or slow stream types, notably 

 Brasenia, thus disclosing a fleeting picture of the Pleistocene 

 environment in Henry County which is considerably different 

 from that of the present in this region.

From a limonitic sandstone of Pleistocene age at a locality 

 2 miles northwest of Jacksonville in Cherokee County, Texas, 

 Julia A. Gardner of the U. S. Geological Survey, collected the 

 following species of plants : 



FaGUS AMERICANA SweCt 



This species is widespread in Pleistocene deposits, although it 

 has never before been encountered as far west as this. It has 

 been recorded from the Pleistocene of Massachusetts, Penn- 

 sylvania, Maryland, West Virginia, Virginia, North Carolina, 

 Alabama, and Mississippi. 



QUERCUS LYRATA Walt 



This, like the associated fossil forms, is characteristic of deep 

 and moist soils. In the recent flora it ranges from Maryland to 

 Florida and Texas, reaching its maximum size in Louisiana and
