Synopsis Taxonomy has among its objectives the learning of the kinds of plants on the earth and their names, of their distributions and their affinities, their distinctions and habitat characteristics and correlation of these facts of knowledge with pertinent scientific data contributed by researchers of related fields. Another objective of taxonomy is the assemblage of knowledge gained. The mere acquisition of the knowledge is sterile unless it is made available to others, only then it is of use and an aid to the progress of civilization. This conversion of taxonomic data from a status of sterility to fertility is accomplished in many ways. This book is an attempt in four parts. Taxonomy-1 (Systematic and Morphology), 2 (Polypetalae), 3 (Gamopetalae) and 4 (Monochlamydea and Monocotyledonae).
