the last time ; the original specimen is in the collection of M. 

 Hebert at the Sorboune. The other Araacarice or Araucarites 

 indicated in the Tertiary formation, and especially A. Sternhergii, 

 Ung.j are in reaUty Sequoicp. 



The following or fourth horizon is one of the most perfectly 

 explored; we place here the floras of Hsering, Sotzka, Saint- 

 Zacharie, Saint-Jean-de-Garguier, Armissan_, and even that of 

 Radoboj, in Croatia. The last two localities appear to be more 

 recent than the others ; but they are united to the former by 

 too many ties to allow of their advantageous separation. The 

 tropical genera which must be indicated in them are the fol- 

 lowing : — 



Ferns : Lindsceaj Dry and. — L. Ciissolii, Gerv. (Armissan.) 

 Palms : Sabalites, Sap. — S. major, Ung. (Hsering^, Radoboj, 



basin of Marseilles, Armissan.) 

 LiLiACEiE : Dracana, L. — D. narbonensis, Gerv. (Armissan.) 

 ARALiACEiE : Aralia, L. — A. Hercules, Sap. (Radoboj, Armis- 

 san.) 

 Sterculiace^ : Sterculia, L. — S. labrusca, Ung. (Sotzka.) 

 JuGLANDEiE: Engelhardtia, Lesch. — E, decora, Sap. (Saint- 

 Zacharie.) E. sotzkiana, Ett. (Sotzka.) E. macroptera, 

 Sap., E. detecta, Sap. (Armissan, Radoboj.) 

 Papilionace^ : Calpurnia, E. Mey. — C. europaa, Sap. (Armis- 

 san.) 

 Copaifera, L. — Casalpinites copaiferinus, Sap. (St. Zacharie, 

 St. Jean-de-Garguier.) Copaifera annissanensis, Sap. 

 (Armissan.) C. radobojana, Ung. (Radoboj.) 

 MiMOSE^: Acacia, Neck. — A, sotzkiana, Ung, (Sotzka.) A, 

 Bousqueti, Sap. (Armissan.) 

 Mimosa, Ad. — M, Pandora, Ung. (Radoboj.) 



These types, selected from among many others as the most 

 certainly determined, are also clearly tropical. The genus 

 Lindsaa, for example, scarcely possesses any species beyond the 

 tropics; and the species from Armissan is very nearly allied 

 to a Javan form, L. javensis, Bl. The Draccence and Palms 

 continue to give the mass of plants a very strongly marked 

 equatorial physiognomy. The Araliacea reproduce the forms 

 of the genus Areopanax of Central America. The genus EngeU 

 hardtia, then at its apogee in Europe, does not now quit the 

 limits of tropical Asia, where, however, it ascends a little upon 

 the mountains both in Nepaul and Java. Lastly, the genera 

 Calpurnia, Copaifera, Acacia, and Mimosa are directly allied to 

 types or forms now peculiar to intertropical Africa and Brazil.
