This volume is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e. they concentrate upon characters which are deemed to be synapomorphic for the lineages and may be applicable only to their early-diverging taxa.
Beyond the treatment of phylogeny and formal taxonomy, the author presents a wide range of information on topics such as the structural characters of grasses, their related functional aspects and particularly corresponding findings from the field of developmental genetics with inclusion of genes and gene products instrumental in the shaping of morphological traits (in which this volume appears unique within this book series); further topics addressed include the contentious time of origin of the family, the emigration of the originally shade-loving grasses out of the forest to form vast grasslands accompanied by the switch of many members to C4 photosynthesis, the impact of herbivores on the silica cycle housed in the grass phytoliths, the reproductive biology of grasses, the domestication of major cereal crops and the affinities of grasses within the newly circumscribed order Poales.
This volume provides a comprehensive overview of existing knowledge on the Poaceae (Gramineae), with major implications in terms of key scientific challenges awaiting future research. It certainly will be of interest both for the grass specialist and also the generalist seeking state-of-the-art information on the diversity of grasses, the most ecologically and economically important of the families of flowering plants.
Ranging from miniature epiphytic orchids to towering trees, and from mangrove forests lining coastal waterways to high-elevation cloud forests, Costa Rica's rich and varied flora dazzles visitors and botanists alike. Tropical Plants of Costa Rica, the first popular treatment to include plants from all regions of the country, is an indispensable guide to native and exotic species found in the neotropics.This book is beautifully illustrated with more than 540 full-color photographs taken in the field, each depicting an entire plant or a closer view of flowers, fruits, or seeds. Instructive pen-and-ink drawings of botanical details also accompany many of the accounts. The text clearly explains each plant's identifying characteristics and reveals fascinating facts about its natural history, chemical properties, economic importance, and medicinal and other uses. Sidebar features throughout the book highlight conservation, ethnobotany, and ecology; their topics include unusual applications for plants, distinct attributes of certain plant families, and plants of particular microhabitats. Tropical Plants of Costa Rica is a wonderful resource for naturalists, students, and researchers, as well as both experienced and first-time visitors to Costa Rica and the American tropics.
The European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 4 contains accounts of 82 families, mostly rather small, but including the Primulaceae (with Primula as its largest genus) and Ericaceae (with Rhododendron, the largest genus in the Flora).
Hawaii's rich volcanic soil and tropical environment provides masterful growing conditions for flora on the islands. Hawaii Trees and Wildflowers is the ideal pocket-sized, folding guide to familiar trees, shrubs and wildflowers. Detailed illustrations highlight over 140 remarkable species. Created and printed in the USA, this guide was updated in 2012 with a new cover design and a back panel map highlighting the state's prominent botanical sanctuaries. Laminated for durability, this lightweight guide is your nature companion to Hawaii.
