Book Description
It is now over 50 years since the grasses of the British Isles were last treated to a book of their own, Hubbard's famous account of 1954, though two more editions were published in 1968 and 1984, with fairly limited changes. Enough has happened to the taxonomy of the family to justify a new BSBI Handbook. Hubbard's original account, still available after more than half a century, has been overtaken by events in an ever-developing taxonomic world and will not be revised again. This new Handbook therefore attempts to bridge the gap between the taxonomy of the 1980s and the new molecular phytogenies that are currently being explored, so that what is being offered is something that users will feel comfortable with (by departing no more than absolutely necessary from familiar taxonomy), but which hints at changes that may be afoot in the near future.

Book Description
Essential reading for both the amateur gardener and professional botanist, this is a definitive and comprehensive guide to all the native and naturalized grasses, sedges, rushes and ferns to be found in the British Isles, and all those that are frequently found in north-western Europe. Over 420 species are described and over 350 are illustrated in full colour plates of exceptional beauty and accuracy. Following the general nomenclature and classification, the author describes each species in detail, stressing the features most important for accurate identification. There is also an invaluable illustrated glossary of technical terms and plant structures.

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
With 444 full page line drawings of introduced, naturalised and casually occurring aliens in Britain, this handbook fulfills a long-felt need, amongst amateur and professional botanists alike, for a field and desk companion to aid in the identification of these plants. The excellent drawings are largely from a collection put together by the late David McClintock, originally with a view to publication in a new illustrated British flora. An invaluable resource, which will benefit botanists both at home and abroad.
