Book Description
The word 'aliens' can be used in many ways, to invoke fear, dislike and fascination. For biologists it is used to indicate organisms that have been introduced by people to new territories. In the British Isles alien plants are common, conspicuous, pestiferous, beautiful, edible - and can be both useful and harmful.

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.

Book Description
Following rigorous testing throughout Britain and Ireland over the last 10 years, this second edition is a much revised version with re-written keys, additional species, phenology and, of course, many new novel identification characters. A few new illustrations have been added where space allows. In addition, the nomenclature has been updated in line with modern taxonomy. Each key has been carefully reviewed and revamped so this version aims to be quicker and more comprehensive in detail than its predecessor, greatly improving on the original work. Additional floral and fruiting characters have been added for some of the more difficult species making it more handy for casual field use.

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.
