This book documents the historical problems associated with an ever-increasing number of commonly-named plants and the resolution of these problems through the introduction of International Codes for both botanical and horticultural nomenclature. The second part of the book comprises an alphabetical glossary of generic and specific plant names and their components, from which the reader may interpret the existing names of plants and construct new names. The third edition includes explanations of the International Codes for both Botanical Nomenclature (2000) and Nomenclature for Cultivated Plants (1995). The expanded glossary incorporates many more commemorative names. Previous Edition Hb (1989): 0-521-36668-2 Previous Edition Pb (1989): 0-521-36675-5
