Includes 2,020 taxa of trees and shrubs important for the European dendrology Provides detailed descriptions of reproductive organs and data on the reproductive biology of the described taxa Contains 6,644 original, high-quality photographs of habits, cones, flowers, fruits and seeds
Have you ever looked at a tree? That may sound like a silly question, but there is so much more to notice about a tree than first meets the eye. Seeing Trees celebrates seldom seen but easily observable tree traits and invites you to watch trees with the same care and sensitivity that birdwatchers watch birds. Many people, for example, are surprised to learn that oaks and maples have flowers, much less flowers that are astonishingly beautiful when viewed up close. Focusing on widely grown trees, this captivating book describes the rewards of careful and regular tree viewing, outlines strategies for improving your observations, and describes some of the most visually interesting tree structures, including leaves, flowers, buds, leaf scars, twigs, and bark. In-depth profiles of ten familiar species—including such beloved trees as white oak, southern magnolia, white pine, and tulip poplar—show you how to recognize and understand many of their most compelling (but usually overlooked) physical features.
After nearly 60 years, with descriptions of more than 270 species and almost 200 illustrations, Textbook of Dendrology continues to remain a top resource for taxonomic and silvicultural information on North American trees. In this new edition, material throughout the text has been updated and expanded to provide current information on tree sizes, damaging diseases and insect pest, economic uses, and silvics. Because of growing concern for the environment, it is even more necessary for students to know and understand the importance of conservation. Many of these issues are incorporated throughout the book.
Preface: With the large number of books now available featureing North American trees, the launching of another on this subject merits perhaps some explanation. Most present tree manuals fall into one of two classes: (1) encyclopedic, such as Sargent's monumental "Silva of North America," later condensed into one volume, which has been adapted by nearly every writer of tree books since it first appeared; and (2) local, as exemplified by the many excellent state and regional manuals. Nearly all these publications have been written from the botanical or taxonomic standpoint and in general treat each species in the same detail. It is obviously impossible for a beginning student in forestry to gain an adequate knowledge of more than a few of the thousand tree species native to this continent. Rather, it is desirable only to cover as many groups (genera) as possible, and to illustrate these with the species of greatest importance to forestry. Such a treatment, accompanied by adequate photographic halftones, has not been available to date, and the authors hope that the present book will fill this need. The native coniferous genera have all been included because of their relative importance, and fewer numbers; but several families, and many genera species of the broadleaved trees have been omitted. It is felt that students of forestry should first know well the commercial species of North America, and then become familiar with the lesser important trees and shrubs of the locality where they may find themselves practicing forestry. The latter must usually be done by the student himself with the aid of a local tree manual. If he has fully appreciated generic characteristics during his training in dendrology, this should not be a difficult procedure. Because this book is not comprhensive for any one portion of the country, it seems best to omit detailed keys and to use instead tables covering family and generic characters. Our experience shows that basic information is more readily assimilated in this form. The does not mean that keys are not of primary importance, and considerable time should be spent with them in identifying local material. The authors will greatly appreciate having any errors called to their attention and will also welcome comments or criticism from those using the book in teaching or otherwise. Most of the photographs were taken with one of the modern miniature cameras whose remarkable depth of focus has made possible many otherwise unattainable pictures. William M. Harlow, Ellwood S.

Gardening can be frustratingly shrouded in secrecy. Fickle plants make seemingly spontaneous decisions to bloom or bust, seeds sprout magically in the blink of an eye, and deep-rooted mysteries unfold underground and out of sight. Understanding basic botany is like unlocking a horticultural code; fortunately learning a little science can reveal the secrets of the botanical universe and shed some light on what’s really going on in your garden. Practical Botany for Gardeners provides an elegant and accessible introduction to the world of botany. It presents the essentials that every gardener needs to know, connecting explanations of scientific facts with useful gardening tips. Flip to the roots section and you’ll not only learn how different types of roots support a plant but also find that adding fungi to soil aids growth. The pruning section both defines “lateral buds” and explains how far back on a shoot to cut in order to propagate them. The book breaks down key areas and terminology with easy-to-navigate chapters arranged by theme, such as plant types, plant parts, inner workings, and external factors. “Great Botanists” and “Botany in Action” boxes delve deeper into the fascinating byways of plant science. This multifaceted book also includes two hundred botanical illustrations and basic diagrams that hearken to the classic roots of botany. Part handbook, part reference, Practical Botany for Gardeners is a beautifully captivating read. It’s a must for garden lovers and backyard botanists who want to grow and nurture their own plant knowledge.
Woody plants such as trees have a significant economic and climatic influence on global economies and ecologies. This completely revised classic book is an up-to-date synthesis of the intensive research devoted to woody plants published in the second edition, with additional important aspects from the authors' previous book, Growth Control in Woody Plants. Intended primarily as a reference for researchers, the interdisciplinary nature of the book makes it useful to a broad range of scientists and researchers from agroforesters, agronomists, and arborists to plant pathologists and soil scientists. This third edition provides crutial updates to many chapters, including: responses of plants to elevated CO2; the process and regulation of cambial growth; photoinhibition and photoprotection of photosynthesis; nitrogen metabolism and internal recycling, and more. Revised chapters focus on emerging discoveries of the patterns and processes of woody plant physiology. * The only book to provide recommendations for the use of specific management practices and experimental procedures and equipment *Updated coverage of nearly all topics of interest to woody plant physiologists * Extensive revisions of chapters relating to key processes in growth, photosynthesis, and water relations * More than 500 new references * Examples of molecular-level evidence incorporated in discussion of the role of expansion proteins in plant growth; mechanism of ATP production by coupling factor in photosynthesis; the role of cellulose synthase in cell wall construction; structure-function relationships for aquaporin proteins
