On the Tertiary Flora of Eastern India

Abstract

The available information on the Tertiary flora of eastern India is reviewed. The distribution of some genera between the middle Tertiary period and now shows a considerable difference, indicating a trend of migration towards south and east. But there are other genera which show little difference in their distribution. A comparative study of the middle Tertiary flora of Europe, North America, the Indo-Malayan region and eastern India has been made and the general features in their vegetation are indicated. No clue is yet available on the migration of some temperate genera to the hills of Indo-Malayan region.
