Tl'.e iloras, as we have them at present, are not all equally ancient. 

 They mount up to epochs more or less remote and different. Thus the 

 Mediterranean flora goes back to the Miocene epoch. It possesses, in 

 fact, existing species which have been found fossil in the Tertiary strata by 

 M. Sapnrta and other observers. Certain remarkable species, like the 

 Dwarf Palm, the Laurel, the Fig, the Olive, the Carob, the Pomegranate, 

 the Myrtle, Anagyris foetida, Cneorum tricoccum, Neriuni Oleander', 

 Smilax aspera, have not yet been reported from the Eocene or Miocene 

 beds, but their affinities point clearly to an origin at an epoch when the 

 JMedilerraiiean basin had a climate much more tropical than is the case 

 now. The flora of the Jurassic tuif-bogs is of a more recent date. Its
