Plant Taxonomy - Its Past Role and Future Lines of Action in India

The history of floristic and taxonomic research in India is briefly reviewed and the decline and revival of floristic studies in India is traced.Modern concepts in plant taxonomy are towards the synthesis of orthodox taxonomic practices and modern methodologies. There need not be any clash between the so called alpha and omega taxonomists. All data that can be readily scanned for the species is useful for the taxonomist. The only aspect that has to be considered is the utillty of classification for a specified purpose. A field, or forest botanist needs diagnostic keys based on superficial morphological characters for identification of plants in the field. Characters based on anatomy, embryology chromosome structure and number, palynology, plant alkaloids and protein serum analysis are useful tools for finding out the systematic position of plants of doubtful affinity; however,. these characters cannot be readily used in the field for identification of plants. The herbarium identification of plants is the simple method of retrieval of plant identity through standard specimens properly authenticated by an expert. It does not give legality for the concept of fixity of species as wrongly alluded to by some non-taxonomists, since Nomenclatural Type is a constituent element of a taxon and it is not necessarily the most representative element.Some of the lines where taxonomists could play a major role are the inventory listing of plants for the conservation of species, monitoring rate of decline and spread of species, establishment of botanical record centres, environmental education and collaboration with universities for reorientation of teaching methods.The necessity for floristic training is stressed and a syllabus drawn up.
