The family of palms (Palmae or Arecaceae) is of major economic importance, both on a large industrial scale and in peasant agriculture. The palms offer a unique challenge to botanists because of their frequently gigantic size and unusual mechanical properties; they are of interest to evolutionists who wish to know how such an unusual plant form could have evolved and to ecologists who wish to learn about the distinct adaptive features of palms. In this book each organ of the plant and each successive phase in its life-cycle is examined, beginning with seed germination and gradually moving through the vegetative cycle to the production of inflorescence, flower, fruit, and seed, giving a general picture of how the palm 'works'. The information is presented in systematic form. Much of the recent extensive literature on palm biology is summarized and the relationship of the palms to other flowering plants is discussed. This book will be of value both to academic botanists and agronomists.

When this book was first published in 1978, tropical forests were unquestionably the largest scientifically unexplored region of the world, and being rapidly depleted by short-term exploitation. Species were being rendered extinct at a rate that is probably greater than the rate at which they are being discovered. This book is an assessment of scientific knowledge of tropical tree biology - construction, development, physiology, reproductive biology and evolution - set against a background of community ecology and forest structure. Its emphasis is on the study of the individual tree as a living system integrated into the larger forest community. The book publishes the results of the Fourth Cabot Symposium held at the Harvard Forest in 1976 and presents the special knowledge of the participants, each an expert in a special field. Much of the subject matter is presented in the form of reviews, making information easily accessible to an interested nonspecialist audience.
