This critical Flora provides a definitive account of the native species, naturalised species, frequent garden escapes and casuals found in the British Isles. Full keys and descriptions will enable the user to name all plants occurring in the wild, plus some ornamental trees and shrubs. For the first time detailed accounts of all the large apomictic genera are given and many infraspecific variants included. Each species entry begins with the accepted Latin name, synonyms and the common English name. A detailed description follows, including information on flowering period, pollination and chromosome number. Separate descriptions are given for infraspecific taxa. Information on the status, ecology and distribution (including worldwide distribution) of the species and infraspecific taxa is also given. Clear black and white line drawings illustrate an extensive glossary and also illuminate the diagnostic features in a number of groups of plants.
The third in a 5-volume series, this is the most comprehensive catalogue of the flora of Great Britain and Ireland--including native species, naturalized species, frequent garden escapes and casuals found in the British Isles.

For the first time detailed accounts of all the large apomictic genera are given and many infraspecific variants included.

This is a standard reference work that no British taxonomist should be without!
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.
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.
The first ever fully-illustrated, fully-mapped guide to the British and Irish flora. Its restriction to the British Isles alone allows far more detail and more local information, and identification which is made easier with the inclusion of extensive maps. Includes specific details about plants appearing in certain areas and coloured maps designed to make location and identification easy, this book also includes details of local specialities for the Isles of Scilly. Also featured is an illustrated survey of recently disappeared British and Irish plants, some of which may return. With over 2000 detailed colour paintings and more than 800 maps, this is the most extensively illustrated wild flower guide to Britain and Ireland yet. Coloured, boxed keys to plants in complex or difficult groups are provided to assist ID. The Wild Flowers of Britain and Ireland features information about grasses, which are often omitted in other, shorter books, along with sedges, rushes, horsetails and clubmosses. Ferns, though not strictly speaking flowering plants, are also included too.
Winner of the 2022 Marsh Book of the Year Award A long-awaited volume in the New Naturalist series examining the trees of Britain.
"The Lichen Flora of Great Britain and Ireland published in 1992 was an outstanding achievement for British Lichenology. It was a pioneering work and the first of its type in Europe. This much enlarged revision reflects the considerable accumulation of new information that has occurred since the publication of the first edition and is symptomatic of the enormous advances in lichen taxonomy over the last two decades. There are keys to 327 genera and 1873 species, which is an increase of 386 species since it was first published. The publication provides detailed information on morphology, chemistry and distribution for each species written in language that is readily accessible, avoiding obscure terminology. Both the glossary and introductory sections have been expanded and the latter includes helpful advice on the identification and examination of lichens. The preparation of this new treatment has involved a large number of contributors both in the UK and overseas and represents the culmination of lichen studies at this time. This book is undoubtedly the standard work for the identification of lichens in Great Britain and Ireland and will be indispensable to all serious students of British, Irish and overseas lichenology and other biologists working in related fields of ecology, pollution, chemical and environmental studies."--Publisher's 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.
Combines the species and habitat approaches to plants and vegetation. This book features 700 plant species that are selected as those which are common, conspicuous or useful ecological indicators; species which collectively make up most of the vegetation in Britain and Ireland.
