Cretaceous, it is probable Ihat at least some genera, as Bumelia, 

 Achras and Calocarpiun originated in America. Jongmans. 



Berry, E. W., A species of Copaifera from the Texas 

 eocene. (Torreya. XV. p. 41—44. 1 Fig. 1915.) 



Tliis paper contains the description of the pods of Copaifera 

 yeguana sp. nov., from the middle Eocene, hard brown clays of the 

 Yegua formation onCedarCreek. As terms of comparison some 

 other fossil pods and a pod of the recent C. langsdorffi Desf. are 

 figured. The author reviews the fossil occurrence of the genus and 

 gives a sketch of the probable origin (equatorial region of America) 

 and geological history of the genus. From America it spread to 

 westeru Africa. During the Oligocene extensive interchanges of 

 terrestrial animal and plant life occurred between Africa and 

 Southern Europe. The oldest known european species of Copai- 

 fera are found in the Aquitanian of Kumi and in beds of the 

 same age in southeastern France. The genus persisted in southern 

 Europe through the greater part of the Miocene and then became 

 extinct on that continent. Jongmans.

Both the Wealden and Potomac floras, on the ground of the 

 structural relations of the containing beds and on the ground of 

 their synchroneity with floras of other areas of a known stratigraphic 

 Position, as determined by invertebrate paleontology, are referred 

 to the Lower Cretaceous. 



The eastern faunas, considered as of the same age as the 

 Morrison by Marsh, Flatcher, and Lull, are underlain by 

 from 200 to 400 feet of Cretaceous Sediments containing a Lower 

 Cretaceous flora which in the Rocky Mountain province is first 

 found in the Kootenai formation, which is partially equivalent to or 

 at most conformable on the Morrison. 



The Kootenai flora appears to be most similar to the Kome flora 

 of Green land, which is not older than Barremian and possibly 

 somewhat younger (perhaps Aptian). 



If this correlation is correct, then at least some of the Morrison 

 must be of Lower Cretaceous age. Jongmans. 



Berry, E. W., Pleistocene plants from Indian Head, Ma- 

 ryland. (Torre5^a. XV. p. 205-208. 1 Fig. 1915.) 



This paper contains the enumeration of the species found in a 

 small collection coUected at the bottom of a dug well at Indian 

 Head in Charles County, Maryland, belonging to the Talbot 

 formation. 



The recognizable species are all recent species: Taxodium disti- 

 chum (L.) Rieh., Fagiis americana Sweet, Quercus michaiixii Nutt., 

 Q. palustria Du Roi, Ulmus americana L., Platanus occidentalis L., 

 Liriodendron tulipifera L. (juvenile leaf, figured), FraxUms ameri- 

 cana (not heretofore recorded from the Pleistocene). All these forms
