Book Description
Excerpt from The Anatomy of Woody Plants It is now forty years since De Bary's classic Comparative Anatomy of the Vegetative Organs of the Phanerogams and Ferns made its appearance. In the interval much has been added to our knowledge, particularly in the paleobotanical and experimental fields. The doctrine of descent, too, has now reached a degree of prominence and importance which it did not possess in De Bary's time. As a consequence, it is desirable that the general subject of the anatomy of the woody or so-called vascular plants should be reviewed, with special reference to its historical and experimental aspects. This is perhaps all the more desirable as an effective counterpoise to the extreme mechanistic tendencies of the time. It will accordingly serve a useful purpose to indicate how large a part of the organization of existing plants is an inheritance from their ancestors of earlier geological times. In De Bary's textbook both paleobotany and development are deliberately eschewed. The first of these is now essential for any adequate comprehension of comparative anatomy in its all-important evolutionary aspects. It is abundantly clear that the most fruitful results from the standpoint of the doctrine of descent are to be derived from the comparative study of extinct and existing plants belonging to the same orders, families, or genera. It is, moreover, obvious that the living forms cannot be interpreted without a knowledge of their past, and that to an even greater degree the organization of fossil plants is a closed book to those who are unfamiliar with the anatomy of allied and still living types. The wide range of facts which must of necessity be covered calls for a somewhat brief and even elementary treatment. Fortunately, since De Bary's time, it has become more and more evident that the study of the development of organs and tissues throws little trustworthy light on the processes of evolution, and consequently that aspect of our subject need receive no more attention than was vouchsafed to it by the great German anatomist nearly half a century ago.

Book Description
This atlas gives a unique assemblage of microscopic slides of wood anatomy and of the respective species in nature and demonstrates the reaction of stem anatomy to environments in which plants form woody stems. It provides insight into the evolution of wood, to the variation of wood anatomy in response to climate and disturbances, and it gives an introduction to the methodology used to study wood. Special attention has been given to the unique feature of secondary growth. In color throughout and with more than 700 both beautiful and instructive illustrations, the wide-ranging scientific content of this book makes it both attractive and unique.

Book Description
Physiology of Woody Plants explains how physiological processes are involved in growth of woody plants and how they are affected by the environment, including the mechanisms of the processes themselves. Organized into 17 chapters, this book discusses the role of plant physiology, as well as the form and structure of woody plant. It also explores the nature and periodicity of shoot, cambial, root, and reproductive growth of trees of the temperate and tropical zones. Other topics elucidated are the process of photosynthesis and respiration, the various substances found in woody plants, plant nutrition, and factors affecting plant growth. This book will be valuable as a text to students and teachers and as a reference to investigators and others who desire a better understanding of how woody plants grow.

Book Description
This atlas presents anatomical descriptions of the xylem, bark and pith of 264 species belonging to 71 families. It highlights the anatomical diversity of trees, shrubs, dwarf shrubs, woody lianas and several of the prominent perennial herbs from the Eastern Mediterranean region, with a focus on the island of Cyprus. The island’s topography and biogeographic history combine to provide a wide range of habitats and diverse flora including widespread, endemic, and ornamental species. The monograph for each species includes a description of the anatomical structures of the stem and twig xylem and the twig’s bark and pith, as well as color micrographs of double-stained sections of each of these plant parts. These entries are accompanied by a photograph and a brief description of the plant including stem wood density, height, habit, flower, leaf and fruit characteristics, and a map showing its geographic and altitudinal distribution in the region. Xylem descriptions follow the IAWA lists of microscopic features for hardwood and softwood identification. For bark and pith descriptions, a new coding system developed by the authors is applied. Lastly, the work offers a key for wood identification that was developed to differentiate between groups of species by using a small number of features that are unambiguous and clearly visible. The atlas will be a valuable guide for botanists, ecologists, foresters, archeologists, horticulturists and paleobotanists.

Book Description
This book is about the developmental anatomy of large, complex plants, particularly of the woody plants that grow and survive for decades or centuries. It is focused on the meaning of that anatomy, that integrated structure, as a determinant of effective function. A pervading theme is that the plant structures that have survived "selection" processes during the eons of organismal evolution, within the larger context of geo logic and climatic evolution, are well attuned to biochemical and biophysical principles that determine and define efficient function. The sets of structure-and-function couples existing in the various plant taxa differ so widely that generalities are often difficult to discern. This diversity is due partly to the broad range of ecological conditions to which higher plant organisms have become adapted under stresses imposed by competition and continual climatic change. It is also due to the tendency of different taxa, with their different complements of inherited information, to respond to similar situations in different ways. Cognizant of this reality, we have tried throughout the book to avoid generalizing too broadly on the basis of data from the relatively small fraction of plant species that have as yet been studied. This book is intended for those who have already studied the anatomy and develop ment of plants. It is addressed to advanced students, teachers, and researchers in the interrelated fields of botany, forestry, horticulture, and agronomy, and to others having professional interests in the culture of woody plants and the stewardship of ecosystems.
