Book Description
New species are discovered every day—and cataloguing all of them has grown into a nearly insurmountable task worldwide. Now, this definitive reference manual acts as a style guide for writing and filing species descriptions. New collecting techniques and new technology have led to a dramatic increase in the number of species that are discovered. Explorations of unstudied regions and new habitats for almost any group of organisms can result in a large number of new species discoveries—and hence the need to be described. Yet there is no one source a student or researcher can readily consult to learn the basic practical aspects of taxonomic procedures. Species description can present a variety of difficulties: Problems arise when new species are not given names because their discoverers do not know how to write a formal species description or when these species are poorly described. Biologists may also have to deal with nomenclatural problems created by previous workers or resulting from new information generated by their own research. This practical resource for scientists and students contains instructions and examples showing how to describe newly discovered species in both the animal and plant kingdoms. With special chapters on publishing taxonomic papers and on ecology in species description, as well as sections covering subspecies, genus-level, and higher taxa descriptions, Describing Species enhances any writer's taxonomic projects, reports, checklists, floras, faunal surveys, revisions, monographs, or guides. The volume is based on current versions of the International Codes of Zoological and Botanical Nomenclature and recognizes that systematics is a global and multicultural exercise. Though Describing Species has been written for an English-speaking audience, it is useful anywhere Taxonomy is spoken and will be a valuable tool for professionals and students in zoology, botany, ecology, paleontology, and other fields of biology.

Book Description
Irises and their relatives are lily-like plants related to the orchid and narcissus families, with whom they share a propensity for large, brightly colored, attractive flowers. Many have longlasting flowersÑIris, Gladiolus, and Freesia are among the most important cut-flower crops in the world. The intricate flowers of the iris family are finely adapted for pollination by a variety of animals, including hummingbirds, sunbirds, beetles, butterflies, moths, wasps, and bees. This intimate connection between flower form and pollination biology reveals how the marvelous range of flower colors, shapes, and scents are vital to the lives of the species. The diversity of Iridaceae is illustrated in more than 200 superb photographs supplemented by expert line drawings. A lifetime of work by the world's expert on Iridaceae is distilled in this definitive account. Botanists, ecologists, naturalists, and gardeners will find this an essential reference.

Book Description
The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.
