The experience which has led to the writing of this book began in 1929 when, examining a species related to Utricularia gibba, I made an observation of some importance in understanding the mechanism of the trap. This begot a desire to study as many other species of the genus as I could obtain for comparison, primarily to determine the validity of my conclusions. My feeling that research in this field was promising was strengthened by the discovery that the pertinent literature was singularly barren of the information most needed, that is to say, precise accounts of the structure of the entrance mechanisms of the traps. And an examination of much herbarium material, because of the meagreness of the underground parts of the terrestrial types resulting from indifferent methods of collection, forced the conclusion that, even had other difficulties inherent in studying dried material not intervened, it would be necessary to obtain adequately preserved specimens. This meant a wide correspondence and, if possible, extensive travel. The uncertainty of achieving the latter made the former imperative.
Highlights the key role played by taxonomy in the conservation and sustainable utilisation of plant biodiversity.
The overall aim of this volume is to review critically the current state of, and future prospects for developments in viral taxonomy.Most of the contributors to this volume have had substantial period of service on the Executive Committee and sub-committees of the International Committee on Taxonomy of Viruses (ICTV).
This volume is intended for reference by the commercial sugar cane grower. Disciplines are covered for the successful production of a sugar cane crop. A number of good books exist on field practices related to the growing of sugar cane. Two examples are R.P. Humbert's The Growing of Sugar Cane and Alex G. Alexander's Sugarcane Physiology. Volumes of technical papers, produced regularly by the International Society of Sugar Cane Technologists, are also a source of reference. Perhaps foremost, local associations, such as the South African Sugar Technologists' Association, do excellent work in this regard. In my forty-five years of experience with the day-to-day problems of producing a satisfactory crop of sugar cane, deciding what should be done to produce such a crop was not straightforward. Although the literature dealing with specific subjects is extensive, I tried to consolidate some of the material to provide the man in the field with information, or an overview of the subject matter.
