Book Description
Following rigorous testing throughout Britain and Ireland over the last 10 years, this second edition is a much revised version with re-written keys, additional species, phenology and, of course, many new novel identification characters. A few new illustrations have been added where space allows. In addition, the nomenclature has been updated in line with modern taxonomy. Each key has been carefully reviewed and revamped so this version aims to be quicker and more comprehensive in detail than its predecessor, greatly improving on the original work. Additional floral and fruiting characters have been added for some of the more difficult species making it more handy for casual field use.

Book Description
The chief aim of this book is the reconstruction of the processes and events that have determined the present flora and vegetation of the British Isles, first of all through the long ages when natural conditions prevailed and cycles of glaciations and recessions and slow geological processes were in charge, and afterwards through the nearer and much shorter span of time during which, from the Neolithic onwards, human interference has progressively and severely altered the scene. This is an exercise in biogeography that Darwin called 'that grand subject, that almost keystone to the laws of nature'. But instead of adopting Darwin's conjectural approach, based largely on circumstantial evidence, what this 1975 second edition achieves is a factual reconstruction of events by records of the actual presence of individual species or genera, in large numbers, at particular sites and specified times through the geological and historic record.

Book Description
Since its first publication in 1991, New Flora of the British Isles has become established as the standard work on the identification of the wild vascular plants of the British Isles. The Flora remains unique in many features, including its full coverage of all British wild plants, its user-friendly organisation, and its specially compiled keys and descriptions. This new edition includes the addition of more than 160 species, so that 4,800 taxa are now covered in varying degrees of detail. It also incorporates the new molecular system of classification based on DNA sequences. Furthermore, it includes 1600 species illustrations, rewritten distributions and an overhaul of the designation of degrees of rarity, with the introduction of a third, less rare, category. These revisions should ensure that this third edition remains the essential reference source for all taxonomists, ecologists, conservationists, plant hunters and biogeographers, whether they be researchers, teachers, students or amateurs.

Book Description
Who first described our native plants? This book attempts to answer that question, starting from almost the dawn of printing, with William Turner's Libellus of 1538. Of course there were medieval herbals in the five centuries or more before Turner, and also there is a vast body of folk-lore, but Turner was the first to describe more than a handful and to do so in print. Thus printed sources are the cornerstone of this work, and the first date is given for each of the 1670 species or aggregates of all the indisputably natives and archaeophytes, including 40 or so species that some have argued as native in the last half-century. But this is supplemented by information from manuscripts and herbaria which enable the display of an earlier date, a date of first evidence, for just under half of that total. The names of the discoverers and the counties where each was first recorded are also given, where known. Though the primary purpose of the book is to show the details of the discovery and recording of each species, it will also show the progress of discovery, leading to somewhat surprising conclusion that most (+/- 85%) of our flora had been described by the 1720s, once the critical, non-lowland and doubtful natives have been omitted. Indeed, the main achievement of these last three centuries has been a consolidation of our knowledge. The very extensive appendices cover the key herbals and floras, the relevant journals, the important works on the history of botany, some of the national herbaria and have a major section of the botanists who actually discovered the plants.--Back cover.

Book Description
This book describes and illustrates in detail the 760 species of mosses currently known to occur in the British Isles and incorporates the most up-to-date information available on classification and nomenclature, together with recent synonyms. The species descriptions provide information on frequency, ecology, geographical relationships and distribution, including information on protected species and those species at risk. For many species there are footnotes to aid identification. In addition to the species descriptions there are descriptions of families and genera and also introductory information on conservation, collection, preservation and examination of material, together with advice on using the keys. An artificial key to genera provides the only workable comprehensive key published in the English language. This second edition incorporates the very considerable advances in our knowledge of mosses made in the last quarter of the twentieth century and will provide a unique resource for all concerned with these fascinating organisms.
