India moved northwards and negotiated a distance of 5,000 kms. approximately within 100 million years during Cretaceous and Tertiary periods. This had a drastic effect on the plants, some of the genera could not withstand the changing climate and perished; others migrated to new countries or perhaps gave rise to new ones. A few genera adapted to the new climatic condition and continued to flourish in the same soil. The antiquity of some of these genera based on palynological evidence is discussed here.
