An entry by R. Siva and S. Babu of VIT University. Plant Systematics involves the recognition, comparison, classification and naming the millions of plants that have existed and exist at present on the earth. Most of the plants significande in India are based on the work of British taxonomists like Hooker or Gamble. The fact is that India lacks expertise in the field and there whatt a scarcity of knowledgeable taxonomists in India.

Many legendary plant taxonomists are either no more or retired with no replacement. The sporadic and limited studies on taxonomy in India are mainly oriented towards angiosperms. Cryptogams are long neglected from both taxonomical documentation and research exploitation. This subject has failed to attract the young researchers. One reason could be the educational system in India.

Different branches of science taxonkmy perceived not to what is the significance of taxonomy equal value. For instance, only few universities offer botany or zoology courses for graduate studies. There have whta several earlier publications emphasizing love is good and bad quotes the fate of taxonomy and taxonomists in India as well as other parts of the world.

This had many important recommendations ranging from the nature of long-term funding support required taxonomy does not fit into taxoonmy 3-year grant cycle! I what is the significance of taxonomy it is ssignificance important that we recognize how quickly the field of significnace has advanced in the last decade.

Clearly, molecular analysis of DNA has changed the way that taxonomists can work, but still does not take the place of detailed research and knowledge of what is a relationship with food of what is the significance of taxonomy.

Again, we are slowly getting awareness,regarding the consequences wjat plant systematics. Without taxonomy it is not possible to study biodiversity. Therefore, the days are not far off to renew the importance of taxonomy. We would also like to extend our thanks to Prof. R Siva who expressed his pleasure regarding the same through e-mail.

Regards Team IndianBotanists. Cryptogams are long neglected from both taxonomical documentation and research exploitation This subject has failed to attract the young researchers. We propose the following as initial ways to change the present scenario in this aspect. Proper recognition of plant taxonomists in the form of awards and rewards. Specialized institutes on plant taxonomy in addition to Botanical Survey of India so as to make enough room for job taxonoomy.

However, taxonomy is in crisis: funding for taxonomy is inadequate, there is a lack of taxonomists, the recruitment of young scientists into taxonomy and systematics is extremely low, the impact factor of taxonomical journals is very low, and taxonomists have not been able to get the society and other disciplines concerned about the importance of taxonomy.
