Book Description
Vascular plant hybrids are numerous and constitute an important feature of our vegetation, but all too often they have been neglected by botanists. Some hybrids between native species are rare, sterile and ephemeral, but others reproduce vegetatively or by seed and have spread beyond the areas where their parents coexist. In addition, numerous hybrids have escaped from gardens to become established in the wild. Interspecific hybridisation is particularly significant as it represents a major evolutionary pathway in flowering plants; frequently it alters the characteristics of both native and alien taxa and it generates new species. The hybrid flora of the British Isles has been studied in more detail than that of any other region, and it therefore provides an ideal opportunity to study the occurrence of hybrids in wild vegetation. This book provides detailed accounts of the 909 hybrids reliably recorded in the wild in the British Isles. Of particular interest to BSBI members are the comprehensive identification notes, including a summary of the differences from the parents, enabling naming and recording of hybrids to a degree not attainable previously. The habitats of the hybrids are outlined and detailed accounts of their distributions provided, with notes on the discovery of many hybrids. There are 388 novel maps illustrating the records of the commoner hybrids in relation to those of their parents. Known chromosome numbers are given for each hybrid and its parents, and information is provided on the hybrid's fertility/sterility and its capacity for vegetative reproduction. Experimental and molecular studies of the hybrids in the British Isles and elsewhere in their ranges are summarised. Briefer notes are given on a further 156 hybrids, including some which are erroneously or doubtfully recorded and others which might potentially occur as escapes from cultivation.

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
The perfect guide to these beautiful and evocative plants, covering all 52 British and Irish species. The orchid family is one of the largest plant families in the world, reaching its highest diversity in the tropics where their exotic and colourful flowers are often truly breathtaking. Britain and Ireland have just 52 species of wild orchid, some of which are rare or scarce, whilst others are surprisingly inconspicuous. Yet, whether large or small, all orchids share flamboyant flower structures and incredible beauty. This pocket guide allows the identification of all species of orchid in the British Isles. It has concise text highlighting ID criteria as well as notes on biology, habitat and conservation, along with stunning colour photographs and accurate range maps based on maps compiled by the Biological Record Centre. This book provides the perfect guide to these beautiful and evocative plants, and is a must for any field naturalist. Part of the Pocket Guides series covering British and European wildlife, including garden birds, butterflies, insects, wild flowers, trees and shrubs and tracks and signs.

Book Description
This field guide will enable the identification of a range of invasive plants and animals now found in Britain. The impact of invasive organisms is second only to habitat loss as a threat to biodiversity and yet, despite increasing ecological awareness, people remain largely unaware of these plants and animals and their potentially devastating impact. Although most biological introductions fail, many prove successful and these can prove disastrous for native fauna and flora. Though these species are of particular concern to conservationists there has previously been no unified guide devoted to their recognition. This book will act both as an ID guide, appealing to the amateur naturalist, and as an important tool for ecologists and land managers attempting to tackle the problem posed by invasive species.

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.
