Book Description
The first book ever on the much maligned nettles of the world presents a story of these followers of mankind and his cattle throughout history. This study centres on the most abundant and sub-cosmopolitan common stinging nettle (Urtica dioica), but also deals with other nettles throughout the world. Tropical tormentors rich in species include the notorious nettle trees with their formidable stings which fascinated the Europeans after their discovery by botanists on the round-the-world trips of exploration in the 17-19th centuries. Many people on their travels will have met the nettle trees of the Indo-Malay region and other stinging nettles in North and South America, India, etc., which sting and have beautiful flowers but are called nettles; these are also dealt with. The first microscopists and their descriptions of the beautiful stinging hair; the uncovering of the mechanism of its action and the more recent elucidation of the toxins causing the characteristic symptoms is a fascinating one and takes up 3 chapters. The book includes the 100 major scientific works published on the common stinging nettle and never brought to the notice of the general public before. The author spent six years studying the ecology of the nettle patch, its invertebrate herbivores (mainly insects) and vertebrate herbivores (cattle, deer, etc.,) and their interactions with other plants: its secret life is recorded in line drawings and photographs (1000+ individual items). It was not possible to publish these in colour but they are in full colour on a CD-ROM (300 dpi) at the back of the book. Covered also are nettle folklore, fibre use in World War I & II, as a food, fodder, herbal medicine, growth as a competitor plant, habitats, sex (unique exploding stamens), breeding systems, variation, evolution etc.!! Some the world's most beautiful butterflies would not exist without nettles.

Book Description
Plants from the genera Urtica, often better known as the stinging nettle, can be distinguished by their stinging hairs, and in some species, their serrated leaf edges. Historical records of the various uses of Urtica date back to at least the Bronze Age (3000-2000 BC). Nettles have traditionally been used as a nutritious food source particularly in

The most important species are Stachyurus himalaicus of Stachyuraceae; Liquidambar formosana, Semiliquidambar cathayensis of Hamamelidaceae; Broussonetia papyrifera, Cudrania cochinchinensis, Cudrania tricuspidata, Ficus carica, Morus alba of Moraceae; Boehmeria nivea and Pouzolzia zeylanica of Urticaceae; Cannabis sativa of Cannabaceae; Ilex asprella, Ilex cornuta, Ilex latifolia, Ilex pubescens of Aquifoliaceae; Euonymus alatus, Tripterygium wilfordii of Celastraceae; Taxillus chinensis, Viscum liquidambaricola of Loranthaceae; Santalum album of Santalaceae; Berchemia lineata, Ventilago leiocarpa, Ziziphus jujuba, Ziziphus jujuba var. Spinosa, Elaeagnus pungens of Rhamnaceae; Citrus aurantium, Citrus grandis var. tomentosa, Citrus medica var. sarcodactylis, Citrus reticulata, Evodia rutaecarpa, Phellodendron chinense and Zanthoxylum bungeanum of Rutaceae. In each specie, it introduces the scientific names, medicinal names, morphologies, habitats, distributions, acquisition and processing methods of these medicinal plants, the content of medicinal properties, therapeutic effects, usage and dosage of these medicinal plants, and attaches unedited color pictures and pictures of part herbal medicines of each species. This book series has 10 volumes in total, which covers over 2000 kinds of Chinese medicines that are commonly used. These volumes not only introduce the efficacy function and some prescriptions of the medicines, but also introduce the biological characteristics of them in detail with clear photos of the habitats, so that readers can identify them in the field. Apart from the growing environment, the books expound the distribution areas and other information to facilitate researches and other applications. The volumes are targeted at readers of general interests and it is also of high referential value for scientific researcher and teachers. It can be used as a guide to researchers, clinical doctors, and students in the department of pharmaceutics and traditional Chinese medicine.

Book Description
The New Manual of Vascular Plants of Northeastern United States and Adjacent Canada is a project by The New York Botanical Garden to fully revise and update the classic Manual by Gleason and Cronquist (1991, NYBG Press). As family treatments are completed for the New Manual, these are being made available as downloadable PDFs. The chief goal of the New Manual is to enable identification of all plants growing spontaneously in a vast region (portions or entirety of 22 states and 5 Canadian provinces). The New Manual includes new tools for plant identification for about 5300 species, amounting to 25% of the total botanical diversity of North America north of Mexico. Approximately 20% of the species included are additions to the 1991 Gleason and Cronquist Manual. In addition, the New Manual provides information on morphology, ecology, phenology, geographic distributions, and conservation status for each species. The New Manual will be indispensable to all those interested in North America's rich botanical resources, including students, conservationists, wildlife managers, educators, and gardeners.

Book Description
This book is an introduction to the science of plant classification and identification, or plant taxonomy. It defines terms used in describing a flowering plant and its parts and presents the characteristics of families of common flowering plants in the Philippines. For a clearer understanding, descriptions are supplemented by drawings and photographs. Plants commonly found in gardens, parks, and vacant lots are used as examples and are therefore readily available for study. A section is also devoted to the establishment and maintenance of a herbarium.

Book Description
The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system; role of seed banks in restoration of plant communities; and seed germination in relation to parental effects, pollen competition, local adaption, climate change and karrikinolide in smoke from burning plants. The database for the world biogeography of seed dormancy has been expanded from 3,580 to about 13,600 species. New insights are presented on seed dormancy and germination ecology of species with specialized life cycles or habitat requirements such as orchids, parasitic, aquatics and halophytes. Information from various fields of science has been combined with seed dormancy data to increase our understanding of the evolutionary/phylogenetic origins and relationships of the various kinds of seed dormancy (and nondormancy) and the conditions under which each may have evolved. This comprehensive synthesis of information on the ecology, biogeography and evolution of seeds provides a thorough overview of whole-seed biology that will facilitate and help focus research efforts. Most wide-ranging and thorough account of whole-seed dormancy available Contains information on dormancy and germination of more than 14,000 species from all the continents – even the two angiosperm species native to the Antarctica continent Includes a taxonomic index so researchers can quickly find information on their study organism(s) and Provides a dichotomous key for the kinds of seed dormancy Topics range from fossil evidence of seed dormancy to molecular biology of seed dormancy Much attention is given to the evolution of kinds of seed dormancy Includes chapters on the basics of how to do seed dormancy studies; on special groups of plants, for example orchids, parasites, aquatics, halophytes; and one chapter devoted to soil seed banks Contains a revised, up-dated classification scheme of seed dormancy, including a formula for each kind of dormancy Detailed attention is given to physiological dormancy, the most common kind of dormancy on earth
