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

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.

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.

Providing an update of the classic Student's Handbook by S.M. Macvicar (1926), this illustrated account of the 300 liverwort and hornwort species on the British and Irish lists is a synthesis of nearly 40 years' study. The detailed descriptions and figures, all prepared by the author, are designed to enable students of these groups to determine the morphologically variable specimens that cause so much difficulty in identification.

For people-watchers everywhere, this is the definitive guide to one of the strangest peoples in existence: the British. Discover the weird, loveable and inexplicable variety of beings populating these isles, each with their own delightful quirks and oddities. Learn to spot the difference between landed gentry and oligarchs, amateur artist and hipster. Recognise the middle-aged couple on their way to Glastonbury and the Brit on holiday. Soon you’ll be spying them everywhere.

First comprehensive guide of its kind, this volume is essential for any study of freshwater algae in the British Isles.
