Tennessee 



A newly opened clay pit near Hilltop, between Paris and 

 Whitlock, and about 2 miles south of the latter town, in Henry 

 County, Tennessee, was studied during the past summer by R. 

 Lee Collins. The clay is dark in color and full of roots and wood. 

 The following plants, which are of considerable interest, were 

 recognized from this deposit :

The loblolly pine is represented by cones, scales or seeds in the 

 Pleistocene of New Jersey, Florida and Alabama. There are two 

 specimens of cones in the present collection which certainly be- 

 long to this species. I have compared the fossils with a series of 

 cones of recent species and the only other modern form that 

 resembles them are the cones of Pinus carihaea Morelet, the slash 

 or swamp pine, of the present coastal region from South Carolina 

 to Louisiana. In the latter the scales have more corrugated tips 

 and the prickles are more slender. I have mutilated the larger 

 fossil specimen sufficiently to get the full outline of one of the 

 scales and there is no doubt but that it represents Pinus taeda. 



In the recent flora this species extends from Cape May, N. J., 

 southward in the Costal Plain to peninsular Florida, and in the 

 Gulf States to the valley of the Colorado River in Texas. It 

 extends up the Mississippi valley to southern Arkansas and the 

 southern boundary of west Tennessee. According to Mohr it 

 rarely gets northward of this southern boundary, nor do I recall 

 having seen it during long continued field work in that part of the 

 state, so that the present fossil occurrence is about 100 miles 

 north of its present northern limit of growth. 



SciRPUs OR Cyperus 



The collection contains 2 specimens of small lenticular achenes 

 lacking their beaks. It is impossible to determine with certainty 

 the genus of Cyperaceae to which they belong. They do not rep-
