INTRODUCTION

Taxonomy is concerned with the laws governing the classification of plants. The term taxonomy includes two Greek words taxis – arrangement and nomos – laws. Plant taxonomy is other name for systematic botany.   Classification, identification, description and naming the plants are the bases of plant taxonomy. The taxonomic knowledge about the plants is based on their form and structure. The knowledge gained through taxonomy is useful in the fields of medicine, agriculture, forestry, etc.

The ultimate aim of classification is to arrange plants in an orderly sequence based upon their similarities.  The closely related plants are kept within a group and unrelated plants are kept far apart in separate groups. The other aim of classification is to establish phylogenetic relationships among the different groups of plants.  The plants that are closely related show more similarities than differences.

The earliest systems of classification were simple and based on one or few characters.  They gave importance to vegetative characters.  The later systems of classification gave more importance to floral characters because floral characters are more stable and permanent.
