Plant taxonomy – Ancient & Modern

Though a single work devoted to botany is unknown, the knowledge of botany among Indians is well known from Vedas, works on Ayurveda, Krishishastra, Arthashastra and lexicons. Terms like Vrkshayurveda and Vanaspatividya tell us that knowledge of botany flourished in the past.  There are few legends which indicate that ancient Indians had several beliefs associated with trees. For instance, Gobhilagrihyasutra mentions that  Asvatta brings danger of fire to one’s residence and that Udumbara leads to a series of optical diseases. Also, Brihatsamhita  speaks of trees like the Asoka and Punnaga which are beneficial to warfare.

1.     LITERATURE REVIEW

a.      Nomenclature

The branch of taxonomy includes nomenclaure and suitable grouping of the plants.In general, plants were named with a scientific approach. A look at the etymology of the synonymns of trees tells us that naming was backed by reason.

v&]  v&ZCyte iD*te  - that which is cut

mhIéh – that which grows on Earth

zaoI - that which has branches

padp – that which drinks sap with roots

té - triNt Anen Aatpm! !– that by which people overcome heat

Anaekh - Ans> zkqSyak< git< hiNt– that which obstructs pace of cart

plazI  – that which has leaves

Agm n gCDtIit– that which doesn’t move

Similar scientific basis was adopted in naming the different varieties of plants based on various factors as provided in the following table.

2.      Properties

Caraka in his Sutrasthana classifies plants as Purgatives and Astringents.The former has about 600 species whereas the latter has about 500 species. Sushruta classifies plants into 37 gana-s on similar basis.

3.     Food value:

Caraka classifies plants into 6 varieties as (Sutrasthana, IV):

ü  xaNyvgR Graminaceae (corns with husk)divided into 11 varieties like zail, ìIih  yv &  gaexUm

Science of the modern times defines Taxonomy as the branch of science that deals with the description, naming and classification of organisms. The term is derived from the ancient Greek words taxis  (arrangement) and nomia (method). Taxonomist aims to group together living forms which have common associates. This science is hierarchical. à various Divisions à Classes à Orders à Families à Genera àSpecies.Thus, species is the basic unit of classification. There were various systems of classifications proposed by the westerners based on :

1.      Habits

2.      Artificial Systems based on numerical classifications

3.      Systems based on form relationships

4.      Systems based on Phylogeny

The first system of classification which is based on habits was put forth by the Greeks and was in vogue for about 10 centuries. The prominent contributors in this field are:

ANALYSIS & SYNTHESIS

The Indian system of classification adopted right from the vedic times to the times of the puranas and other lexicons provide classification based on habits, dietetic value and also on botanical terms. In the modern science systems, the classification is based on habits, natural and artificial methods. The hierarchial system of classification adopted by the modern scientists and the binomial nomenclature adopted by the westerners is absent in our traditional Indian system. The divisions of plants based on properties and food-value tell us that the focus of the Indians had been mainly on finding the usefulness of  each & every plant and putting them under a broad category. In addition to that, since the naming of plants was done by notable morphological features, it appealed  even to the common-man.

2.      CONCLUSION

The paper is an attempt  in presenting a relative picture of the traditional and modern systems of plant-classification.  Based on the findings, it is concluded that in both Indian and Modern systems, there is lot of science involved when it comes to identifying or naming plants. The plants were classed  depending on the knowledge existing at that time about the variety or nature of plants. The Indians had minor variations with respect to definitions of few classes of plant-varieties.The Westerners were fairly uniform on the definitions of various botanical terminologies.

3.      SCOPE OF FUTURE RESEARCH

There is ample scope in taking this forward by exclusively basing the comparison on one extensive and comprehensive system of the modern scientists with that of a smiliar ancient system. Moreover, the scope extends in the area of comparing commonly available and useful plants’ nomenclature in both the systems.This would throw light on areas of overlapping between the two different systems.
