Angiosperms or flowering plants are the dominant plants on earth at this time and have been for the last 100 million years. The classification of Angiosperms resets mostly upon the structure of the flower, which is undoubtedly their most distinctive feature. This is mainly because it is the flower which shows such remarkable plasticity of form. This variability of the structure of the flower in turn reflects the intimate adaptive association of flowers with insects, whose evolution they have closely paralleled.

The present book provides a comprehensive account of the general principles and modern trends in the taxonomy of angiosperms. It brings out the main aims and principles of taxonomy, compares all current systems of classification, and explains intricate rules of plant nomenclature clearly. This well illustrated and dependable text is designed for undergraduate and postgraduate students botany.
