Discusses fossil evidence for the origin of Australian vegetation.

The knowledge of fossil plants and of the history of the vegetable kingdom has, until recently, been so fragmentary that it seemed hopeless to attempt a detailed treatment of the subject of this little book. Our stores of knowledge have, however, been rapidly accumulating in recent years, and we have now arrived at a stage when every new discovery serves to render useful and intelligible a vast number of facts previously fragmentary and of uncertain import. The writer of this work, born in a district rich in fossil plants, began to collect and work at these as a boy, in connection with botanical and geological pursuits. He has thus been engaged in the study of fossil plants for nearly half a century, and, while he has published much on the subject, has endeavoured carefully to keep within the sphere of ascertained facts, and has made it a specialty to collect, as far as possible, what has been published by others. He has also enjoyed opportunities of correspondence or personal intercourse with most of the more eminent workers in the subject. Now, in the evening of his days, he thinks it right to endeavour to place before the world a summary of facts and of his own matured conclusions—feeling, however, that nothing can be final in this matter; and that he can only hope to sketch the present aspect of the subject, and to point the way to new developments, which must go on long after he shall have passed away. The subject is one which has the disadvantage of presupposing some knowledge of the geological history of the earth, and of the classification and structures of modern plants; and in order that all who may please to read the following pages may be placed, as nearly as possible, on the same level, this introductory chapter will be devoted to a short statement of the general facts of geological chronology, and of the natural divisions of the vegetable kingdom in their relations to that chronology. The crust of the earth, as we somewhat modestly term that portion of its outer shell which is open to our observation, consists of many beds of rock superimposed on each other, and which must have been deposited successively, beginning with the lowest. This is proved by the structure of the beds themselves, by the markings on their surfaces, and by the remains of animals and plants which they contain; all these appearances indicating that each successive bed must have been the surface before it was covered by the next.

"The lack of discussion of the life histories of modular organisms is the weakness of this book that I most regret. . . . Modular organisms are different. " S. C. Steams: The Evolution of Life Histories (1992) Life-history theory endeavours to increase our understanding of the processe,s whereby the broad features of the life cycles of organisms, such as the timing and magnitude of reproduction, have evolved. Although reproductive traits have dominated as study objects due to their immediate importance for evolutionary success, much work has also been conducted on patterns of development, growth and senescence, as well as on the shifts in resource allocation related to these processes. The basic axiom of life-history theory is that patterns of life histories, such as reproductive traits, are subject to evolutionary explanation. This idea can be traced back at least as far as Darwin's Origin of Species (1859). In his discussion of plant domestication, Darwin wrote: "I cannot doubt that the continued selection of slight variations, either in the leaves, the flowers, or the fruit, will produce races differing from each other chiefly in these characters". Darwin was impressed by the success of plant breeders in moulding the growth and reproductive parameters of cultivated plants, and believed that natural selection could have a similar impact in natural populations.

A Cultural History of Plants in the Post-Classical Era covers the period from 500 to 1400, ranging across northern and central Europe to the Mediterranean, and from the Byzantine and Arabic Empires to the Persian World, India, and China. This was an age of empires and fluctuating borders, presenting a changing mosaic of environments, populations, and cultural practices. Many of the ancient uses and meanings of plants were preserved, but these were overlaid with new developments in agriculture, landscapes, medicine, eating habits, and art. The six-volume set of the Cultural History of Plants presents the first comprehensive history of the uses and meanings of plants from prehistory to today. The themes covered in each volume are plants as staple foods; plants as luxury foods; trade and exploration; plant technology and science; plants and medicine; plants in culture; plants as natural ornaments; the representation of plants. Alain Touwaide is Scientific Director at the Institute for the Preservation of Medical Traditions, Washington, D.C., USA. A Cultural History of Plants in the Post-Classical Era is the second volume in the six-volume set, A Cultural History of Plants, also available online as part of Bloomsbury Cultural History, a fully-searchable digital library (see www.bloomsburyculturalhistory.com). General Editors: Annette Giesecke, University of Delaware, USA, and David Mabberley, University of Oxford, UK.

A comprehensive guide detailing the story of healing with herbs from pre-history to modern times. Drawing on her decades of experience as an established herbalist and historian, Christina Stapley presents an encyclopaedic and accessible guide to the theory and practice of Western herbal medicine throughout history. Spanning an impressive timeline of two thousand years, A History of Plant Medicine is a fundamental textbook for students and practitioners of herbal medicine to enhance their study and practice, as well as an enjoyable narrative for anyone interested in this bountiful and fascinating subject. Using a wealth of historical research, Stapley invites readers on a journey from the beginnings of botany, through to the development of Greek and Celtic medicine, including Roman medicine and the Roman settlement of Britain. It moves on to explore Anglo-Saxon leechbooks, Arabic Medicine, Norman influenced physicians and surgeons and pharmacy in the Medieval Period. It also examines the physic garden in Britain, Culpeper and Astrology, concluding with changes and developments to herbal medicine in the modern day. As well as offering a detailed chronology of herbalism in the Western world, A History of Plant Medicine provides practical advice and recipes which can be implemented in the daily practice of the modern herbalist. Stapley creates tangible threads through time, focusing on the most used herbs at different periods, and following them over the centuries. Special emphasis is put upon seeking out effective recipes and practices abandoned in favour of new ideas and foreign herbs, and each is presented clearly and accessibly throughout. A History of Plant Medicine also illuminates the work of women physicians across the ages, whose work has often been obscured or forgotten. Ultimately, A History of Plant Medicine invites herbalists (both new and old), historians, or interested lay people, to re-evaluate their relationship with herbal medicine, in understanding how different herbs are perceived in the light of knowledge and beliefs at particular times, in order to aid a greater understanding of the Western herbal tradition.
