Angiosperm represents the largest as well as the most successful group of plants within the Plant Kingdom. Taxonomy is concerned with the laws governing the classification of plants. Taxonomy of Angiosperms started with two approaches viz. Empirical and interpretative approach. 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. This Course offers an overall analysis and study of Angiosperm taxonomy.
