Book Description
This volume should be seen as an extension to both the existing publications for pollen identification and traditional floras based on gross morphology. In the NEPF a pollen type provides the basis for a hierarchical construction around which the diversity of palynomorphs can be organised and interpreted. It is not a physical specimen in a herbarium, as is the type of a species name, but rather a published account comprising detailed descriptions and comprehensive illustration. In Volume VIII of "The Northwest European Pollen Flora" the following families are studied: Osmundaceae, Azollaceae, Salviniaceae, Droseraceae, Aizoaceae, Aristolochiaceae, Rhamnaceae, Vitaceae, Betulaceae (incl. Corylaceae), Myricaceae, Onagracea and Lythraceae.

Book Description
Palynology, the science of fossil and recent spores/pollen grains, is of high importance, both in many pure and applied fields of the natural sciences (e.g. in botany, geology, climatology, archeology and medicine). It is not only an auxiliary science, but can certainly stand for itself. The "classical" palynology subjects, pollen morphology and systematics, are at present influenced by many modern approaches, e.g. from cell biology, analytical electron microscopy, morphometry, up to com- puter-aided-design of threedimensional reconstruction. In recent years fascinating informations have come to light, and new insights have given rise to changing scientific concepts. During the XIV International Botanical Congress, held in Berlin in 1987, a symposium was devoted to important topics of (actuo)palynology. Nine of its innovative, major contributions are presented in this volume. They cover the comparative morphology and the systematic/evolutionary significance of pollen/spores in critical taxa, aspects of pollen development (cytoskeleton), the substructure of sporopollenin, homologies between wall strata of ferns, gymnosperms and angiosperms, and important (but so far underrated) physical aspects of harmomegathy and pollen transport (fluid versus solid mechanics).

Book Description
The field of plant taxonomy has transformed rapidly over the past fifteen years, especially with regard to improvements in cladistic analysis and the use of new molecular data. The second edition of this popular resource reflects these far-reaching and dramatic developments with more than 3,000 new references and many new figures. Synthesizing current research and trends, Plant Taxonomy now provides the most up-to-date overview in relation to monographic, biodiversity, and evolutionary studies, and continues to be an essential resource for students and scholars. This text is divided into two parts: Part 1 explains the principles of taxonomy, including the importance of systematics, characters, concepts of categories, and different approaches to biological classification. Part 2 outlines the different types of data used in plant taxonomic studies with suggestions on their efficacy and modes of presentation and evaluation. This section also lists the equipment and financial resources required for gathering each type of data. References throughout the book illuminate the historical development of taxonomic terminology and philosophy while citations offer further study. Plant Taxonomy is also a personal story of what it means to be a practicing taxonomist and to view these activities within a meaningful conceptual framework. Tod F. Stuessy recalls the progression of his own work and shares his belief that the most creative taxonomy is done by those who have a strong conceptual grasp of their own research.

Book Description
This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.
