Agnes Chase's First Book of Grasses by Lynn G. Clark,Richard W. Pohl Pdf
For almost seventy-five years, Agnes Chase's First Book of Grasses has been the classic guide to the structure of this complex group of plants. Clearly written and copiously illustrated with line drawings, the book is accessible to those with little or no botanical training, yet it also is respected by botanists as an authoritative introduction to agrostology. Last updated in 1959, the book now has been thoroughly revised to reflect current scientific knowledge, nomenclature, and classification. Divided into twelve lessons, the guide first surveys the basic vegetative and reproductive parts of a grass plant, then in succeeding lessons takes up increasingly more complex modifications. Formally recognized groups of grasses are discussed in a taxonomic context, with the principal focus on grass structures, particularly those of inflorescences and spikelets. Virtually all of the species discussed are illustrated with detailed line drawings. With the addition in this edition of a lesson on bamboos, coverage now extends to tropical regions and encompasses all major groups of grasses. The book also includes a short biography of Agnes Chase in the foreword and, for the first time in this edition, a glossary accompanies the appendices on grass classification.
Grasses, Sedges, Rushes by Lauren Brown,Ted Elliman Pdf
A practical and expertly illustrated field guide to over one hundred grasses, sedges, and rushes "No one will be able to claim that the identification of grasses, sedges, and rushes, which are of fundamental importance both environmentally and economically, are simply 'too difficult' after they have learned to use this excellent guide."--Peter Raven, President Emeritus, Missouri Botanical Garden This elegant and easy-to-use guide is an updated and amended revision of Lauren Brown's seminal Grasses: An Identification Guide, which was first published in 1979. While maintaining the spirit and goals of the original edition--a portable, straightforward, and user-friendly guide for naturalists and plant enthusiasts--the new edition features more than one hundred grasses, sedges, and rushes that are presented with line drawings and color photographs, concise descriptions, and details on the uses of various plants throughout history. In addition, the authors are careful to highlight the subtle differences in similar species to avoid confusion, as well as offering relevant notes on plant survival strategies, invasiveness, and how different plants fit within the broader ecological landscape. Devoid of technical jargon, this volume is an indispensable tool for those curious about the often-overlooked grasses, sedges, and rushes that surround us.

Grasses of the British Isles by Thomas A. Cope,Alan J. Gray Pdf
It is now over 50 years since the grasses of the British Isles were last treated to a book of their own, Hubbard's famous account of 1954, though two more editions were published in 1968 and 1984, with fairly limited changes. Enough has happened to the taxonomy of the family to justify a new BSBI Handbook. Hubbard's original account, still available after more than half a century, has been overtaken by events in an ever-developing taxonomic world and will not be revised again. This new Handbook therefore attempts to bridge the gap between the taxonomy of the 1980s and the new molecular phytogenies that are currently being explored, so that what is being offered is something that users will feel comfortable with (by departing no more than absolutely necessary from familiar taxonomy), but which hints at changes that may be afoot in the near future.

Manual of Grasses for North America by Mary E. Barkworth,Laurel K. Anderton,Kathleen M. Capels,Sandy Long,Michael B. Piep Pdf
Grasses are the world’s most important plants. They are the dominant species over large parts of the earth’s land surface, a fact that is reflected in the many different words that exist for grasslands, words such as prairie, veldt, palouse, and pampas to mention just a few. As a group, grasses are of major ecological importance, as soil binders and providers of shelter and food for wild animals, both large and small. Some grasses, such as wheat, rice, corn, barley, rye, tef, and sugar cane are major sources of calories for humans and their livestock; others, primarily bamboos, are used for construction, tools, paper, and fabric. More recently, the seed catalogs that tantalize gardeners each winter have borne witness to an increasing appreciation of the aesthetic value of grasses. The Manual of Grasses for North America is designed as a successor to the classic volume by Hitchcock and Chase. It reflects current taxonomic thought and includes keys, illustrations, and distribution maps for the nearly 900 native and 400 introduced species that have been found in North America north of Mexico. In addition, it presents keys and illustrations for several species that are known only in cultivation or are of major agricultural significance, either as progenitors of bread wheat and corn or as a major threat to North American agriculture because of their ability to hybridize with crop species. The Manual of Grasses for North America is a major reference work for grasses that will retain its value for many years.
A thought experiment in future-shock survivalism' Robert MacFarlane 'Gripping ... of all science fiction's apocalypses, this is one of the most haunting' Financial Times WITH AN INTRODUCTION BY ROBERT MACFARLANE A post-apocalyptic vision of the world pushed to the brink by famine, John Christopher's science fiction masterpiece The Death of Grass includes an introduction by Robert MacFarlane in Penguin Modern Classics. At first the virus wiping out grass and crops is of little concern to John Custance. It has decimated Asia, causing mass starvation and riots, but Europe is safe and a counter-virus is expected any day. Except, it turns out, the governments have been lying to their people. When the deadly disease hits Britain, society starts to descend into barbarism. As John and his family try to make it across country to the safety of his brother's farm in a hidden valley, their humanity is tested to its very limits. A chilling psychological thriller and one of the greatest post-apocalyptic novels ever written, The Death of Grass shows people struggling to hold on to their identities as the familiar world disintegrates - and the terrible price they must pay for surviving. John Christopher (1922-2012) was the pen name of Samuel Youd, a prolific writer of science fiction. His novels were popular during the 1950s and 1960s, most notably The Death Of Grass (1956), The World in Winter (1962), and Wrinkle in the Skin (1965), all works depicting ordinary people struggling in the midst of apocalyptic catastrophes. In 1966 he started writing science-fiction for adolescents; The Tripods trilogy, the Prince in Waiting trilogy (also known as the Sword of the Spirits trilogy) and The Lotus Caves are still widely read today. Ifyou enjoyed The Death of Grass, you might like John Wyndham's The Day of the Triffids, also available in Penguin Modern Classics.
