Miocene Epoch. 91 



and acer, and even by many cases of specific identity, seem 

 to make a nearer approach to the Pliocene flora ; 8^/i, A part 

 of the Lignites of Bohemia, and particularly those of Altsattel, 

 whose fossils, described by M. de Sternberg and M. Ross- 

 masssler, generally agree with those of the other localities 

 already mentioned. The other Lignites of Bohemia, those 

 of Bilin and of Comothau in particular, enter completely 

 into the Pliocene flora; 9/A, Hoerring in the Tyrol, and 

 Radoboj in Croatia, of which M. Unger has so well described 

 the numerous impressions in his Ghloris Protogcea, and which 

 have almost become the type of the Miocene flora. 



" With the exception of the Lignite formations of the neigh- 

 bourhood of Cassel and Frankfort — the species of which have 

 often numerous points of connection with those of CEningen 

 and Parschlug, and which enter rather into the Pliocene flora 

 < — the diff'erent localities I have mentioned have numerous re- 

 lations between them as to their fossil vegetables. Thus, the 

 Nymphea Arethusse is found in the Meulieres or Buhrstone 

 of Paris, and in the marls of Armissan ; the Flabellaria rha- 

 pifolia and maxima recur at Hoering in the Tyrol, at Radoboj 

 in Croatia, and in the superior sandstones of the environs of 

 Angers and Perigneux. 



" The Callitrites Brongniartii, Endl., is likewise met with in 

 the formations of Armissan, Aix, in Provence, at Hoering and 

 Radoboj. 



" Lastly, the Steinhauera globosa of the Altsattel Lignites 

 in Bohemia, is likewise found in the sandstone of the vicinity 

 of Maus ; and the Platanus Hercules of Radoboj, in Croatia, 

 has been sent to me from Armissan, near Narbonne, by M. 

 Toumal. 



" These facts would probably multiply by a more attentive 

 study of the difl^erent localities ; but as it is, they leave little 

 doubt as to the synchronism of the greater part of these local 

 formations." 



In the Flora of the Miocene formations, Amphigenous 

 cryptogams occur, represented by Algee and mushrooms; Acro- 

 genous cryptogams, represented by mosses, ferns, and Cha- 

 racea? ; Monocotyledons, among which we find Naiades, Gra- 

 mineae, Liliaceae, and Palms ; of the Gymnospermous dicoty-
