Missouri, also older Eocene; from a bed of Lignite at Brandon, 

 Vt. ; and from Bellingham Bay, Vancouver's Island, on the Pa- 

 cific. Among the plants are species of Plane-tree, Oak, Poplar, Maple, 

 Hickory, Dog-wood, Magnolia, Cinnamon, Fig, Conifers, Palms, etc. 

 Palm-leaves have been found as far north as the Upper Missouri 

 region. Specimens collected by Hayden are of the fan-palm 

 family, — a species of Sabal, — and one leaf when entire must have 

 had a spread of twelve feet. 



The plants of the beds of Mississippi, the Upper Missouri, and 

 other localities mentioned, are closely related, according to both 



Figs. 793-797. 



Fig. 793, Quercus myrtifolia ? ; 794, Cinnamomum Mississippiense; 795, Calamopsis Danas ; 

 796, Fagus ferrugiuea ? ; 797, Carpolithes irregularis. 



Lesquereux and Newberry, to those of the Miocene of Europe, and 

 are also much like those of the present era. It follows, then, if 

 the order of the beds is correctly determined, — as can hardly be 

 doubted, — that the forests of the American Eocene resembled 

 those of the European Miocene, and even of modern America. 



Among the genera of the older Lignite beds distinguished by Lesquereux and 

 Newberry are (1) Angiosi^erms, — Quercus, Garya, Populus, Acer, Morus, Carjrinus,
