If one was to judge from Mammalia prodigious changes since Glacial period probably in plants. The Carboniferous Flora wd make one suppose plants have changed as much as everything or more. Think of Mammal of N. America S. America Europe Siberia. On this view the nature of plants during both periods of Tertiary so different, as really hardly to signify. In recurring warmth-period -tropical plants first divided??
Insects wd perhaps be better test. In Eocene no doubt Tropical in England, but during [illeg], I think, only little more Tropical than now.
Read about Tertiary plan fossils in Pictet & Lyell.
