The whole Flora as yet known consists of 24 Families, 64 Genera ; 

 comprising 163 species+. 



The following are the general results of Prof. Goeppert's re- 

 searches. 



A considerable number of tertiary species of plants (especially 

 PlantcB cellidares) are still hving. 



The flora of the Amber being destitute of tropical and sub-tropical 

 forms, it is to be referred to the Pliocene period. 



The remains only of forest-plants have been preserved m the 

 Amber. 



This flora much resembles the present, especially in the Cellular 

 plants ; the CujpressinecB, however, are now almost wholly wanting in 

 our latitudes, and the Abietinece and the JEricinece are not abundant. 

 The four species, of TJmia, Andromeda, and Sedum, which are iden- 

 tical with the living, are indeed northern forms ; on the other hand, 

 the Lihocedrus Chilensis is found on the Andes of Southern ChUi. 



The flora of the northern parts of Europe, Asia, and America is at 

 present less rich in species of Cvjiressinece and AhietinecB, than that 

 of the Amber ; although it possesses some of the species found in 

 the latter : nor are the existing northern species of Coniferce so rich 



* Of these, eight (the species determined from the fossil wood) afford Amber, 

 t The number of species may probably be raised to about 180, by additions from 

 about 50 specimens of wMch the relations are barely determinable.
