Presents a succinct yet comprehensive overview of medicinal and poisonous plants including those used for their mind-altering effects. Details approximately 350 species from Aloe vera and Ephedra sinica to Cannabis sativa and Coffea arabica—detailing their botanical, geographical, pharmacological, and toxicological data as well as the chemical structures of the active compounds in each. Full of colour photographs, this volume provides easy reference and quick answers, and will be an invaluable reference not only for those in the health care field but also for those growing their own medicinal herb gardens, as well as anyone who needs a quick answer to whether a plant is a panacea or a poison.

Renowned garden expert Chris Beardshaw takes us on a journey though history’s most fascinating plants, flowers, vegetables and herbs: the ones that changed the world, the ones that almost did, and the ones that certainly didn’t! Ranging from Roman times to present day and even covering future plant-inventions, this book is a fascinating compendium of stories about the plants and vegetables we see, nurture and consume every day. If you have ever wondered why carrots are supposed to help you see in the dark or why we hang fairy lights and decorations on our Christmas trees then this is the book for you – a fun and quirky new volume that offers unique exploration of our planet’s most fascinating plants.

Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators. Although there are other scientific means of dating climatic and environmental events, dendrochronology provides the most reliable of all paleorecords. Dendrochronology can be applied to very old trees to provide long-term records of past temperature, rainfall, fire, insect outbreaks, landslides, hurricanes, and ice storms–to name only a few events.This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines.Individual chapters address the composition of wood, methods of field and laboratory study, dendroarchaeology, dendroclimatology, dendroecology, dendrogeomorphology, and dendrochemistry. The book also provides thorough introductions to common computer programs and methods of statistical analysis. In the final chapter, the author describes “frontiers in dendrochronology,” with an eye toward future directions in the field. He concludes with several useful appendixes, including a listing of tree and shrub species that have been used successfully by dendrochronologists. Throughout, photographs and illustrations visually represent the state of knowledge in the field. Also available in hardcover [stock id 34331].

An accessible introduction to the way in which botanical evidence is identified, collected and analysed in criminal cases. Increasingly this form of evidence is becoming more important in forensic investigation and yet there are few trained botanists able to assist in such cases. This book is intended to show how useful simple collection methods and standard plant analysis can be in the course of such investigations and is written in a clear and accessible manner to enhance understanding of the subject for the non-specialist.
Clearly structured throughout, this book combines well known collection techniques in a field oriented format that can be used for casework. Collection of evidence differs from formal plant collection in that most professional plant collectors are gathering entire plants or significant portions of a plant for permanent storage and reference. Evidence frequently consists of fragments, sometimes exceedingly tiny. Exemplars (examples of reference plants) are collections of plants made in the manner a botanist would collect them. These collections are necessary to link or exclude evidence to or from a scene. Various methods that allow easy collection, transportation, and preservation of evidence are detailed throughout the book.
This book is written for those who have no formal background working with plants. It can be used as a practical guide for students taking forensic science courses, law enforcement training, legal courses, and as a template for plant collection at any scene where plants occur and where rules or laws are involved. Veterinarians, various environmental agencies, anthropologists, and archaeologists are examples of disciplines that are more recently in need of plant evidence. Veterinarians are becoming more active in pursuing cases of animals that have been abused or are victims of illegal killing. Anthropologists and archaeologists are often called to help with body recovery in outdoor environments. Environmental agencies are increasingly forced to adopt rules for resource protection, are in need of a guide for procedures for plant evidence collection and application.
The format of the book is designed to present the reader with all the information needed to conduct a botanical analysis of a crime scene; to highlight the forensic significance of the botanical evidence that may be present; how to collect that evidence in the correct manner and preserve and store that evidence appropriately- also shows how to conduct a laboratory analysis of the plants. Also available in hardcover [stock id 34586].

Beautifully illustrated, this informative and entertaining guide unravels the mysteries of botanical Latin. Over 3000 Latin names are listed alphabetically, showing how botanical Latin can reveal where a plant originally comes from, and properties such as its shape, form, colour, taste and smell. Each name is clearly defined and accompanied by a pronunciation guide, and the pages are filled with attractive botanical illustrations. Fascinating feature spreads retell the adventures of important plant hunters such as Sir Joseph Banks and Alexander von Humboldt, and explain how their discoveries affect the way our gardens look today. Individual plants are also profiled throughout, showing how their names can illuminate their hidden histories. Aided by this book, every gardener, and their garden, will benefit from uncovering the wealth of information that lies within the remarkable world of Latin binomials.
