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.

The Discovery of the Native Flora of Britain & Ireland
Author: D. Pearman
Publisher:
ISBN: 9780901158529
Category : Plants
Languages : en
Pages : 488
Book Description
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.

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.

The Elms
Author: C.P. Dunn
Publisher: Springer Science & Business Media
ISBN: 1461545072
Category : Science
Languages : en
Pages : 386
Book Description
Elms occur, both naturally and cultivated, throughout much of the temperate world. Because of their high tolerance to extreme growing conditions and their widespread distribution, elms have been widely planted in cities, towns and rural areas throughout North America and northern Europe. As such, their current demise due to several pandemics of Dutch elm disease has spurred a huge body of research on breeding for disease resistance, conservation and systematics. The Elms: Breeding, Conservation and Disease Management provides the current state of knowledge in these areas and is an important reference work for pathologists, breeders, taxonomists, and arborists.

New Flora of the British Isles
Author: Clive Stace
Publisher: Cambridge University Press
ISBN: 1139486497
Category : Science
Languages : en
Pages : 1267
Book Description
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.
