Book excerpt: 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 excerpt: The native British flora is today relatively ant species on the continent, such as Picea impoverished. Today the British Isles has a abies (Norway spruce), did not get into Britain flora of only about 1500 species of native in time. However, we must not over flowering plants. France and Spain, each emphasize the importance of Britain being an geographically only about twice the area, island. A comparison of floras on either side have 3-4 times as many species each. The of the English Channel shows that there are comparison is more marked when consider species present in England and not in ing the endemic species, those specialities of northern France as well as vice versa. Many each geographical region which grow of the species present in northern France but nowhere else. If only normal sexual species absent from England are weeds adapted to are considered, then there are only about 13 French agriculture. Others may be limited endemic species in the British Isles while 1000 not by the sea but by the climate. species are endemic to Spain. Nevertheless, the example of Ireland, However, the poverty of the British flora is which was isolated much earlier than the rest not a unique phenomenon. The whole of of the British Isles, does show the effect of north-western Europe, an area including isolation because it does have a much poorer northern France and much of Germany and flora and fauna.
Download or read book New Flora of the British Isles written by Clive Stace and published by Cambridge University Press. This book was released on 2010-04-01 with total page 1267 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book History of the British Flora written by Godwin and published by Cambridge University Press. This book was released on 1984-07-19 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chief aim of this book is the reconstruction of the processes and events that have determined the present flora and vegetation of the British Isles, first of all through the long ages when natural conditions prevailed and cycles of glaciations and recessions and slow geological processes were in charge, and afterwards through the nearer and much shorter span of time during which, from the Neolithic onwards, human interference has progressively and severely altered the scene. This is an exercise in biogeography that Darwin called 'that grand subject, that almost keystone to the laws of nature'. But instead of adopting Darwin's conjectural approach, based largely on circumstantial evidence, what this 1975 second edition achieves is a factual reconstruction of events by records of the actual presence of individual species or genera, in large numbers, at particular sites and specified times through the geological and historic record.

Available in PDF, EPUB and Kindle. Book excerpt: "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.
