Plant taxonomy, the science of classifying and naming the plants antedate recorded history. Even in the early civilization of India, China and Egypt practiced a sort of plant taxonomy as a new a few good number of plants particularly those of food and medicinal value. We find that this branch is originated only since 200-250 b.c. and and always credit is given to Theopastrus and Aristotle as the beginner in this branch. one of the earliest Indian works dealing with plants in a scientific manner is ‘Vrikshyurveda’. It was compiled by Parashar. This was based on study of comparativemorphology of plants. With this origin we find that the taxonomy was changing its concepts and the basis and hence classification was also changing its concepts. It traveled from herbs, shrubs, and trees to oil yielding fiber. Then it came on artificial system from that the natural system and today its base is phylogenetic, which is only imaginary, unpractical and no utility Much more voluminous works are being done to the westerns and modern science and the use of it to the Mankind is very less. But for each subject. We must also refer to the eastern and Ancient Indian Science. In the ancient India much more literature was available on various Sciences. But because of the colonization of the western people much more is destroyed very few are available and in that we can get knowledge more advance and useful than today.
