Nomenclature is the basic groundwork on which the edifice of plant taxonomy and biosystematics is built; and on this rests the realm of the entire plant sciences. The present book on Plant Nomenclature provides a simplified version of the International Code of Botanical Nomenclature for the benefit of students, research workers in botany and horticulture as well as teachers for a proper understanding of the nomenclatural problems and assigning a correct name to a plant species.
