Book Description
To be published in 30 volumes, Flora of North America represents the first and only comprehensive taxonomic guide to the extraordinary diversity of plant life blanketing our continent north of Mexico. The collaborative effort of more than 30 major U.S. and Canadian botanical institutions, this ground-breaking scholarly series revises and synthesizes literally thousands of floristic monographs and regional floras published over the last three centuries. In addition, this series distills the original herbarium, laboratory, and field work of hundreds of contributors -- all of them leading botanists and taxonomic authorities who have joined forces to develop this century's premier tool for identifying, understanding, and conserving North America's priceless floristic heritage. Concise, easy to use, and beautifully bound and illustrated, Flora of North America is an indispensable working resource for botanists, conservationists, ecologists, agronomists, foresters, range and land managers, horticulturists -- anyone with a series interest in the distribution, habitat, morphology, and survival of the wide-ranging plant life around us. New lower price! The list price of all volumes in the Flora of North America series have now been reduced to $95 (from $120)

Book Description
Flora of North America Volume 27 will be the first volume of three on the bryphytes (mosses, hornworts, and liverworts). Thirty-five authors treat the first half of the mosses, including 32 of the acrocarpous families, with introductory chapters on bryophyte morphology, the history of North America floristic bryology, and economic uses. The 84 species of sphagnum, of considerable economic importance, are fully treated. The number of taxa total 37 genera and 621 species. The taxa are fully described and keyed, illustrated with an estimated 136 panels of detailed line drawings of two or more species each, and geographic distributions are provided at the province and state level. This is the first installment of a full compilation of the mosses for North America since A. J. Grout's Moss Flora of North America of 60 years ago, and will be an invaluable reference.

Book Description
Plant diseases play an important role on our daily lives. Most of plant diseases are visible and are caused by biotic and/or abiotic factors. Symptoms are usually the results of a morphological change, alteration or damage to plant tissue and/or cells due to an interference of the plant’s metabolism. All basic structures of vascular plants are subject to attack by pathogens. The failure in accurate disease diagnosis and management may lead to huge losses in plant production and related commodities, which causes nutritional food scarcity. Typically, the appearance of a biotic symptom will indicate the relatively late stage of an infection and/or colonization of a pathogen. Expert detection, accurate diagnosis, and timely management play a significant role in keeping plants free from pathogens. In this book expert scholars share their research knowledge and key literature which are vital toward the diagnosis of plant diseases across the globe, addressing traditional plant pathology techniques, as well as advanced molecular diagnostic approach.

Book Description
Invasive alien species (IAS) are a menace to agricultural crops and ornamental plants worldwide due to climate change and global warming. They vector serious human and animal diseases and endanger biological diversity through competition and niche displacement. This book addresses issues pertaining to introduction pathways of invasive species, their bionomics, dispersal, risk assessment, economic impact, and possible management and control options. It provides comprehensive information on global invasion, economic impact, and management options for the red palm weevil, spotted wing Drosophila, and the South American tomato pinworm. Additionally, it examines the economic utilization of invasive plant species from the families Asteraceae and Cactaceae as means of management. University teachers and researchers in the fields of entomology, ecology, and environment, as well as students, will find this book useful.

Book Description
Flavonoids are secondary plant products that have previously been shown to be helpful in determining relationships among plant groups. This work presents comprehensively the occurrence, patterns of variation, and systematic and evolutionary importance of flavonoids in the sunflower family (Asteraceae), the largest family of flowering plants (23,000 species). It gathers together the more than 2500 reports of flavonoids in Asteraceae published between 1950 to the present and interprets these data in context of new taxonomic (especially generic) alignments. The authors discuss flavonoid patterns with reference to modern phylogenetic studies based on morphology and DNA data. This book provides, therefore, the most exhaustive synthesis and evaluation of the systematic and evolutionary import of flavonoids ever accomplished for any large family of angiosperms.
