New Flora of the British Isles is the standard work on British plant identification. It is designed to be user-friendly, serving as a practical database for taxonomists, ecologists, conservationists, plant geographers, teachers and students, as well as for amateur botanists and plant hunters. The Flora includes all native, naturalised and crop plants, and all recurrent casuals. Over 150 pages of specially prepared illustrations are provided to aid identification of critical groups and less familiar alien taxa. Technical terms are kept to an essential minimum. In this new edition the text has been revised thoroughly throughout and adjustments made to many of the illustrations to ensure that the work is fully up-to-date. Over 200 species and subspecies have been added, together with numerous extra hybrids, bringing the total number of taxa covered to over 4500.

Periodic comprehensive overviews of the status of the diverse organisms that make up wildlife are essential to determining trends, threats and future prospects. Just over 25 years ago, leading authorities on different kinds of wildlife came together to prepare an assessment of their status of a wide range of organisms in Great Britain and Ireland i

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.

An authoritative two-volume overview of the distribution of the wild plants of Great Britain and Ireland Plant Atlas 2020 presents the results of field surveys by the Botanical Society of Britain and Ireland, building on past atlas surveys undertaken by the Botanical Society in the early and late twentieth century. Drawing on the work of thousands of botanists who covered the entirety of Britain and Ireland between 2000 and 2019, this two-volume book features introductory chapters that provide a detailed assessment of the changes to the region’s flora over the past hundred years. Distribution maps and accompanying text and graphics display the phenology, altitudinal range, and time-series trends for 2,616 native and alien species and 247 hybrids. With more than 30 million records gathered during the project, Plant Atlas 2020 will serve as an essential resource for the study and conservation of these wild plants and their vitally important habitats for decades to come. The most in-depth survey of British and Irish flora ever undertaken, based on more than 30 million individual records Covers 2,616 native and alien species and 247 hybrids Features a wealth of distribution maps and infographics, accompanied by informative text A must-have reference book for botanists, field naturalists, conservation organizations, government agencies, and anyone interested in the diverse plant life of Great Britain and Ireland

"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 flowering plants, ferns and conifers of the British Isles. The Flora remains unique in many features, including its full coverage of all our wild plants in one volume, it's user-friendly organisation, and its specially compiled keys and descriptions. All native, naturalised, crop and repeatedly occurring casual plants are included...More than 200 species and hybrids have been added to the text of this fourth edition, and, in order to establish it as a truly twenty-first century flora, alien species that have not been recorded in the British Isles since 1999 (about 90 taxa) are omitted from the main text. The third edition (2010) was the first British Flora to incorporate the new molecular system of classification based primarily on DNA sequences, a scheme that is expected to endure for centuries to come at the family level. However, new discoveries from this research are continually being made, necessitating numerous further changes, particularly at the genus level, which have been incorporated in this fourth edition."--Back cover.

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.

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.
