A valuable contribution to the on-going discussions on evolution within the Orchid family. Dressler's work delimits several major natural groups and emphasises areas needing further study.
An updated guide to the production, science, and uses of vanilla Vanilla is a flavor and fragrance in foods, cosmetics, pharmaceuticals, and a wealth of other products. Now in its second edition, the Handbook of Vanilla Science and Technology provides a comprehensive and updated review of the science and technology used in these items’ production and supply. Featuring contributions from an international range of experts, this revised edition covers a multitude of topics, including agricultural production, global markets, analytical methods, sensory analysis, food and fragrance applications, organic farming and fair trade, botanical diseases, and novel uses. The Handbook of Vanilla Science and Technology, Second Edition is a vital resource for producers, distributors, and scientists involved in vanilla’s growth and utilization, and offers readers: A guide to the cultivation, extraction, analysis, DNA sequencing, and marketing of vanilla Information on the production of vanilla in a range of countries such as Mexico, Australia, Costa Rica, and India Guidelines on the quality control of vanilla beans and extracts Information on fair trade and the future of vanilla
Reprint of the 1981 Smithsonian edition with a new taxonomy note by Dressler. Contains fine reproductions of the original 95 plates (on 16 pages). Annotation copyrighted by Book News, Inc., Portland, OR
This book contains a detailed survey of the biology of terrestrial orchids, from seed dispersal to establishment and life of the adult plant.
This work follows on from the 1995 publication on European orchids. The atlas is now completed with a second part, containing data on the pollination of orchids of the continents of America, Asia, Africa (including Madagascar) and Australia (including New Zealand).;The first part of the book is adapted from the general account of the previous publication and is extended with chapters on taxonomy and pollinators. The general account deals with such things as the history, evolution, morphology, chemistry and genetics of orchid pollination. The second part gives a systematic account for each continent of all well known details. The text is designed to have relevance for orchid lovers whether professional or amateur.
Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

"The Marie Selby Botanical Gardens Illustrated Dictionary of Orchid Genera is the most comprehensive and extensively illustrated account of orchid genera to date. Its concise entries provide details of nomenclature, classification, original publication, etymology, and geographic range, along with a brief description and color images of representative flowers."--BOOK JACKET.
