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 in the Amber- 
is flora much resembles the present, especially in the Cellular 
plants; the Cupressinew, however, are now almost wholly wanting in 
our latitudes, and the Abietinee and the Ericinew are not abundant. 
The four species, of Thuia, Andromeda, and Sedum, which are iden- 
tical with the living, are indeed northern forms ; on the other hand, the 
Libocedrus Chilensis is found on the Andes of Southern Chili.

Amber is never found isolated in large or small masses in the bitu-

cells, which never contain yellow masses of resin, but only dark-brown
