396 E. W. Berry — Pleistocene Flora of Alabama. 



Tertiary arctic species, is probably identical or closely allied 

 with the present species. 



The present occurrence consists of leaves which are infre- 

 quent at locality No. 4.

This species is a common element in the recent flora of 

 Alabama in low woods particularly along stream banks. It 

 ranges northward to Yirginia, Illinois and Kansas and south- 

 ward to Florida and Texas. As a fossil it was recorded from 

 the Pleistocene near Columbus, Kentucky, by Lesquereux, and 

 from the Neuse River in North Carolina and Abercrombe 

 Landing on the Chattahoochee Kiver in Alabama by the writer 

 (loc. cit.). Two species of Ulmus occur in the Pleistocene of 

 Maryland, Ulmus racemosa is recorded from the Pleistocene 

 near Morgantown, West Yirginia, and both the latter and 

 Ulmus americana occur in the interglacial beds of the Don 

 valley in Canada. 



The present record is based upon infrequent leaves from 

 locality No. 4. 



Phoradendeon flavescens (Pursh) Nutt. 



A species, in the modern flora, of the Carolinian and Louisi- 

 anian zones ranging northward as far as New Jersey and 

 common throughout Alabama. It has not previously been 

 recorded as a fossil, although certain European Upper Pliocene 

 remains have been described as Viscojyhyllum. However, it is 

 not at all certain that these are not related to the genus Pistia 

 rather than to Yisoum. 



The present record is based on the characteristic leaves of 

 the modern species found at localities No. 1 (common) and 

 No. 6 (1 specimen). 



Liriodendron TULiPiFEKA Linne. 



Berry, Amer. Nat., vol. xli, p. 695, 1907. Torreya, vol. ix, p. 71, fig. 1, 

 1909. 



This common mesophile forest type of the Alleghanian, 

 Carolinian, and Louisianian zones flnds its present southern 

 limit in Alabama at about latitude 31°. Previous fossil 

 records are based on fruits from Abercrombe Landing on the 

 Chattahoochee River in Alabama and upon abundant leaves 

 from the Wicomico formation near Weldon, North Carolina. 



The present record is based upon leaf fragments from 

 locality No. 1 and upon a leaf and a carpel from locality 

 No. 3.'
