摘要

The importance of taxonomic and systematic studies in relation to biodiversity is rightly being emphasized in Current Science1-4. I wish to point out that taxonomy and systematic studies of plant fossils are also being neglected due to an overemphasis on geologic interpretations. In strict sense, palaeobotany is a fundamental science related with the taxonomic study of plant fossils and it reveals the floristic history of the earth at different time scales. Such studies aid in determining the origin, evolution, diversification and establishment of various plant groups in the geologic past. This provides a perspective on the present-day plant communities. The investigation of plant fossils from sedimentary basins of India has helped to identify a new plant group, Pentoxylae, which is unique in having its own systematic position.
