360 M. Brongniart on the different Floras which 



minate, especially if we admit, as positively belonging to this 

 family, the various fraits of the Isle of Sheppey which Mr. Bower- 

 bank has described under the name of Cupressinites, and of 

 which M. Endlicher has formed the genera Callitrites, Frenelites, 

 and Solenostrobiis. If these fruits really belonged to the European 

 vegetation, they indicate very peculiar generic forms, which are 

 probably entirely destroyed. 



3. The existence of several large species of Palms, equally de- 

 monstrated by the presence of their leaves and their stems. 



2. Miocene Epoch. 



This middle epoch of the tertiary formations appears to me to 

 comprise the following localities among those which have fur- 

 nished materials for the study of the vegetation of the tertiary 

 period : — 



1. In the environs of Paris, the upper or Fontainebleau sands, 

 and the millstones (Meul. Par.) which crown our hills; 2. the 

 Bands with impressions, in the environs of Mans and Angers, and 

 probably those of Bergerac, department of Dordogne; 3. a por- 

 tion of the tertiary formations of Auvergne, and particularly 

 those of the mountain of Gergovia, beds which, from their im- 

 pressions, appear more ancient than those of Menat, but which 

 perhaps all belong to different stages of the pliocene epoch; 

 4. the freshwater formations of Armissan, near Narbonne, the 

 gypsum of Aix in Provence, the lignites of Provence, the fossil 

 plants of which are scarcely known ; lastly the lacustrine forma- 

 tions, rich in the wood of Palms and fasciculated stems of Mo- 

 nocotyledons, of Upper Provence, near Apt and Castellane ; 5. a 

 portion of the tertiary beds of Italy, and particularly those of 

 Superga, near Turin ; 6. the molasse of Switzerland with its 

 lignites, at Lausanne, Kopfnac and Horgen, containing the re- 

 mains of Palms. 



7. The lignites of the banks of the Rhine, near Cologne and 

 Bonn, at Friesdorf, Liblar, &c., sometimes containing the wood 

 of Palms, and those of the Wetterau at Nidda, near Frankfort, 

 and in other places; as well as those of Meisner, near Cassel, 

 which appear of the same epoch, although those of the Wetterau 

 seem more to approach the pliocene flora, by the abundance of 

 certain genera of Dicotyledons, such as Juglans and Acer^ and 

 even by several cases of specific identity. 



8. A portion of the lignites of Bohemia, and particulai-ly those 

 of Altsattel, the fossils of which, described by M. Sternberg and 

 M. Rossmassler, agree generally with those of the other localities 

 already cited. Other lignites of Bohemia, those of Bilin and 

 Comothau especially, pass completely into the pliocene flora. 



9. Horing in Tyrol, and Radoboj in Croatia, the numerous
