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
