This volume highlights the new synthesis of pollination biology and plant mating systems which is rejuvenating the two-hundred-year-old discipline of floral biology. It provides a current examination of the evolution and functional significance of floral traits in animal-pollinated plants, combining ecological and genetic studies with natural history approaches and theoretical modeling. Divided into three sections, the book begins with the first English translation of Christian Konrad. Sprengel's introduction to his classic work and a historical analysis of his observations. The second section addresses current conceptual problems in floral biology, concentrating on floral diversification, floral longevity, pollen dispersal and mating patterns, the ecology of geitonogamous pollination, and flower size dimorphism in plants with unisexual flowers. The final chapters of the book examine model systems and include the evolution of floral morphology and function, deceit pollination, reproductive success and gender variation, stylar polymorphisms, and the evolution of flowers in relation to insect pollinators on islands. With its a detailed treatment of the selective forces shaping floral diversification in animal-pollinated plants, Floral Biology provides ecologists, evolutionary biologists, and botanists with a wealth of current information. Everyone interested in the evolution of flowering plants will benefit from this timely, authoritative resource on the interactions between insects and plants.

Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The role of pollination in governing mating patterns in plant populations inextricably links the evolution of pollination and mating systems. Despite the close functional link between pollination and mating, research conducted for most of this century on these two fundamental aspects of plant reproduction has taken quite separate courses. This has resulted in suprisingly little cross-fertilization between the fields of pollination biology on the one hand and plant mating-system studies on the other. The separation of the two areas has largely resulted from the different backgrounds and approaches adopted by workers in these fields. Most pollination studies have been ecological in nature with a strong emphasis on field research and until recently few workers considered how the mechanics of pollen dispersal might influence mating patterns and individual plant fitness. In contrast, work on plant mating patterns has often been conducted in an ecological vacuum largely devoid of information on the environmental and demographic context in which mating occurs. Mating-system research has been dominated by population genetic and theoretical perspectives with surprisingly little consideration given to the proximate ecological factors responsible for causing a particular pattern of mating to occur.

Reuchlin’s keen interest in Jewish mysticism resulted in the original publication of this work in 1517. The first part of this dialogue reflects on messianism, the second part on the relation of the Pythagorean system to the Kabbalah, and the third on the "practical Kabbalah." The German humanist Johann Reuchlin (1455-1522) defended the value of Jewish scholarship and literature when it was unwise and unpopular to do so. As G. Lloyd Jones points out, "A marked mistrust of the Jews had developed among Christian scholars during the later Middle Ages. It was claimed that the rabbis had purposely falsified the text of the Old Testament and given erroneous explanations of passages which were capable of a christological interpretation." Christian scholars most certainly did not advocate learning the Hebrew language. Reuchlin was exceptional in pursuing and promoting Hebrew studies, believing that a working knowledge of that language was essential for a true appreciation of the Bible and rabbinic literature. Refusing to join Christian contemporaries who wished to destroy the Kabbalah and the Talmud, he spoke out against ignorance. Christians could have a useful dialogue with Jews if they gained a thorough knowledge of the writings of Jewish exegetes and philosophers. Toward that end he proposed university endowments that aroused the fury of opponents and led to the famous "battle of the books." Reuchlin's keen interest in Jewish mysticism resulted in the publication of De arte cabalistica in 1517. The first part of this dialogue reflects on messianism, the second part on the relation of the Pythagorean system to the Kabbalah, and tdhe third on the "practical Kabbalah." According to Jones, "Reuchlin demonstrates how Christians can make profitable use of Jewish mystical writings, and therefore shares with the reader his understanding of the art of the Kabbalah." That art will reach more readers in this modern English-language translation by Martin and Sarah Goodman. It reinforces the historical importance of the man who prevented the destruction of Jewish books and anticipated the more liberal climate of the Reformation.
