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.

A portable guide to identifying plants in the British Isles, based on New Flora of the British Isles.

Originally published in paperback in 1990, this book's purpose was the accurate identification of all British plants.

"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.

Table of contents

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

The close-up photographs allow you to examine each plant in detail - so you will know your English from your Spanish bluebell - and because it is done by colour instead of name, it is much easier to navigate. Full of fascinating information, including where and when you will find the flowers, their characteristics, and anecdotes on their historical background with their medicinal and culinary uses. You don't even need to go out into the field to enjoy these beautiful and sometimes elusive flowers.

Crop wild relatives (CWR) are species closely related to crop plants which can contribute beneficial traits such as pest or disease resistance and yield improvement. Through an examination of national, regional and global context of CWR, this text presents methodologies and case studies that provide recommendations for global conservation and use.

This volume discusses the latest online plant genomics and cytogenetic resources used by plant evolutionary biologists and plant breeders. The chapters in this book are organized into two parts. Part One looks at plant genomic databases, and covers topics such as plant phenomics and genomics research data repositories, InpactorDB, PlanTEenrichment, and PEATmoss, among others. Part Two looks at cytogenetics and chromosome-related databases, and covers resources such as the Plant DNA C-values database, the Delphineae Chromosome Database (DCDB), B-chrom, a Database on B-chromosomes, and the Plant Ribosomal DNA Database. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective databases and offers explicit directions on how to access and get the most of these resources. Cutting-edge and comprehensive, Plant Genomic and Cytogenetic Databases is a valuable instrument for any plant science researcher who is interested in learning more about the wealth of information that is available through the use of these databases.

Planned in five volumes, this new, critical Flora provides a definitive account of the native species, naturalized species, frequent garden escapes and casuals found in the British Isles. Full keys and descriptions should enable the botanist, researcher or informed amateur to name all plants occurring in the wild, plus some ornamental trees and shrubs. Detailed accounts of all the large apomictic genera are given and many infraspecific variants. Each species entry begins with the accepted Latin name, synonyms and the common English name. A detailed description follows, with separate descriptions being given for infraspecific taxa. Includes information on status, ecology and distribution. Clear black and white line drawings illustrate an extensive glossary and also illuminate the diagnostic features of a number of groups of plants.
