The pliocene epoch, examined in Europe, — for I have inten- 

 tionally excluded from the preceding list some fossils from the 

 Antilles which are referred to these formations, — presents as its 

 peculiar character, extreme analogy with the existing flora of 

 temperate regions of the northern hemisphere, — I do not say of 

 Europe, for this pliocene flora comprehends several genera foreign 

 to our existing flora, but peculiar to the vegetation of America or 

 temperate Asia. There are, taking for granted the correctness 

 of the generic relations established by the botanists to whom 

 these determinations are due, Taxodium, Salisburia, Comptonia, 

 Liquidamhar, Nyssa, Robinia, Gleditschia, Bauhinia, Cassia, Aca- 

 cia, Rhus, Julians, Ceanothus, Celastrus, Sapindus, Liriodendron, 

 Capparis, Sideroxylon, Achras and Symplocos, all genera foreign 

 to temperate Europe, in which they have been found in a fossil 

 condition, but which are, for the most part, still met with in the 

 temperate regions of other parts of the globe. 



Of other genera still existing in Europe, but now only contain- 

 ing a small number of species there, we find many more in the 

 fossil condition : for example the Maples, fourteen species of which 

 are enumerated in this flora of the pliocene epoch, and the Oaks, 

 which amount to thirteen. It should be remarked that these 

 species come from two or three narrowly circumscribed localities, 

 which, at the present time, probably do not present more than 

 three or four species of these genera in a radius of several leagues. 

 Lastly, another character to which I have already drawn atten- 

 tion, and which renders this flora still more diff*erent from that 

 of our epoch, is the absence or at least the small number and the 

 nature of the plants with gamopetalous corollas.
