Interest in this unique plant has grown dramatically over the last ten years. This book provides an overview of the plant and recent finding s concerning its cell biology, biochemistry, development, morphology, phylogeny, paleobotany, as well as possible applications in chemistry and medicine. It also covers environmental aspects and the relationshi p between Ginko Biloba and humans. It will be of wide interest to bota nists, horticulturists and scientists working on this aractive and use ful plant, and aims to both stimulate further study and contribute to the development of new fields in Ginkgo research.

Interest in Ginkgo biloba has grown dramatically in the last 10 years, along with a corresponding increase in research on this unique plant. This book provides an overview and recent findings concerning cell biology, biochemistry, development, morphology, phylogeny, paleobotany, as well as possible applications in chemistry and medicine. It also covers environmental aspects and the relationship between G. biloba and humans. The book will be of wide interest to botanists, horticulturists and scientists working on this attractive and useful plant. This book commemorates the hundredth anniversary of the discovery of Ginkgo sperm by Sakugoro Hirase and will both stimulate further study, and contribute to the development of new fields in Ginkgo research.

In this field guide to the future, esteemed Harvard University botanist Peter Del Tredici unveils the plants that will become even more dominant in urban environments under projected future environmental conditions. These plants are the most important and most common plants in cities. Learning what they are and the role they play, he writes, will help us all make cities more livable and enjoyable. With more than 1000 photos, readers can easily identify these powerful plants. Learn about the fascinating cultural history of each plant.

Characterized by an abundance of pavement, reflected heat, polluted air and contaminated soil, our cities and towns may seem harsh and unwelcoming to vegetation. However, there are a number of plants that manage to grow spontaneously in sidewalk cracks and roadside meridians, flourish along chain-link fences and railroad tracks, line the banks of streams and rivers, and emerge in the midst of landscape plantings and trampled lawns. On their own and free of charge, these plants provide ecological services including temperature reduction, oxygen production, carbon storage, food and habitat for wildlife, pollution mitigation, and erosion control on slopes. Around the world, wild plants help to make urban environments more habitable for people.

Peter Del Tredici's lushly illustrated field guide to wild urban plants of the northeastern United States is the first of its kind. While it covers the area bounded by Montreal, Boston, Washington, D.C. and Detroit, it is broadly applicable to temperate urban environments across North America. The book covers 222 species that flourish without human assistance or approval. Rather than vilifying such plants as weeds, Del Tredici stresses that it is important to notice, recognize, and appreciate their contribution to the quality of urban life. Indeed their very toughness in the face of heat islands, elevated levels of carbon dioxide and ubiquitous contamination is indicative of the important role they have to play in helping humans adapt to the challenges presented by urbanization, globalization and climate change.

The species accounts 158 main entries plus 64 secondary species-feature descriptive information including scientific name and taxonomic authority, common names, botanical family, life form, place of origin, and identification features. Del Tredici focuses especially on their habitat preferences, environmental functions, and cultural significance. Each entry is accompanied by original full-color photographs by the author which show the plants' characteristics and growth forms in their typical habitats. Wild Urban Plants of the Northeast will help readers learn to see these plants-the natural vegetation of the urban environment-with fresh appreciation and understanding."
