Book Description
This text summarizes the results of studies on the pollination ecology of the unique family Compositae (Asteraceae). The complex structural and functional specializations of the capitulum (or head) for pollinator attraction and pollen transfer are described in detail. An attempt is made to identify the influence of these specializations on the development and the function of other floral parts. The remarkable sex polymorphism of the Compositae head, which has caused much confusion amongst students is traced to this influence and characterized as a secondary modification. The central concept in the book is taht pollination ecology is the guiding factor in Compositae evolution.

Book Description
Secondary pollen presentation is presentation of pollen to vectors by structures other than anthers, either passively or via a specialized protection and delivery system. The main part of the book describes secondary pollen presentation genus-by-genus in 25 families. The subject has never been extensively reviewed, although secondary pollen presentation occurs in the largest family of flowering plants, the Asteraceae (Compositae), and a large family of great economic importance, the Leguminosae. Now material from the scattered literature is brought together and supplemented with original observations. Many species are illustrated and each family is individually discussed. The last two chapters provide an overview of the whole topic. All the main functions that secondary pollen presentation may perform can be carried out in other plants without it. It is concluded from this that the evolution of secondary pollen presentation has been subject to constraint and canalization. The floral biology of most plants with secondary pollen presentation has not been adequately studied. Appendix 1 points to a wide range of topics on which research at various technical and academic levels is needed. The book should also become a reference work for morphologists, systematists, and floral ecologists.

Book Description
"This spectacular book does full justice to the Compositae (Asteraceae), the largest and most successful flowering plant family with some 1700 genera and 24,000 species. It is an indispensable reference, providing the most up-to-date hypotheses of phylogenetic relationships in the family based on molecular and morphological characters, along with the corresponding subfamilial and tribal classification. The 2009 work not only integrates the extensive molecular phylogenetic analyses conducted in the last 25 years, but also uses these to produce a metatree for about 900 taxa of Compositae. The book contains 44 chapters, contributed by 80 authors, covering the history, economic importance, character variation, and systematic and phylogenetic diversity of the family. The emphasis of this work is phylogenetic; its chapters provide a detailed, current, and thoroughly documented presentation of the major (and not so major) clades in the family, citing some 2632 references. Like the Compositae, the book is massive, diverse, and fascinating. It is beautifully illustrated, with 170 figures, and an additional 108 cladograms (all consistently color-coded, based on the geographic range of the included taxa); within these figures are displayed 443 color photographs, clearly demonstrating the amazing array of floral and vegetative form expressed by members of the clade." --NHBS Environment Bookstore.

Book Description
This book presents a comprehensive overview of our current understanding of mutualism origin, plant–pollinator specificity, mutualism stability, and reciprocal diversification. In particular, it focuses on the natural history and evolutionary history of the third example of obligate pollination mutualism, leafflower–leafflower moth association, which was discovered in the plant family Phyllanthaceae by the lead editor and then established by the editors and their coworkers as an ideal model system for studies of mutualism and the coevolutionary process. This work brings together the knowledge they have gained through an array of research conducted using different approaches, ranging from taxonomy, phylogenetics, ecology, and evolutionary biology to biogeography. Richly illustrated with numerous original color photographs, the volume consists of 13 chapters and is divided into three main parts: natural history, ecology, and evolution. It begins by showcasing numerous examples of plant–animal interactions and their origins to guide readers in the world of leafflowers and their pollinators. The immense diversity of Phyllanthaceae and pollinator moths is then explored, and in the following 7 chapters mutualism is discussed from a range of ecological and evolutionary points of view. The final chapter presents a review of the evolution and variety of obligate pollination mutualisms. This book offers researchers and students in the field of ecology, botany, evolutionary biology, pollination biology, entomology, and tropical biology fascinating insights into why such a costly pollination system has evolved and why Phyllanthaceae is so diverse despite the inconspicuousness of their flowers.

Book Description
This study is the most comprehensive and up-to-date overview of style morphology and anatomy of the plant family Asteraceae (or Compositae; asters, daisies, sunflowers), using the most current generalized phylogenetic tree based on molecular data as reference. The Asteraceae are the largest plant family (one out of about every 10 species of the flowering plants belongs to this family); they include about 25,000 currently accepted species in 14 subfamilies and 44 tribes. The authors distinguish 49 style types in the Asteraceae. The style characters are compared with other features that indicate a systematic relationship. The style of an individual flower of the Asteraceae is one of the most important floral organs in two respects: Firstly, the characteristics of the style contribute to the systematics of the family, secondly, the different forms of styles are of utmost importance to secondary pollen presentation. The latter allows for optimizing pollination by pollen portioning, a widespread phenomenon in angiosperms. Combining both morphology and function, the style types represent eight possibilities of secondary pollen presentation, which can be subsumed into four main functional categories. Style characteristics and mechanisms of secondary pollen presentation are plotted in up-to-date phylogenetic trees to illustrate and discuss possible evolutionary trends in the Asteraceae. Evaluating style characters and the position of the style tip within the anther tube shortly before anthesis now allows; in most cases; to easily predict the mechanism of secondary pollen presentation. The different style types are exquisitely illustrated by high quality greyscale and colour images and numerous line drawings. The study is complemented by extensive bibliography, a table of the specimens studied (species, collection, etc.) and an index. This style atlas is useful not only to botanists (especially synantherologists) and entomologists, but addresses a wider audience interested more generally in the systematics of flowering plants and the evolution of floral characters and function.
