Download or read book Guide to Standard Floras of the World written by David G. Frodin and published by Cambridge University Press. This book was released on 2001-06-14 with total page 1136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.
Download or read book Euphorbia in Southern Africa written by Peter V. Bruyns and published by Springer Nature. This book was released on 2022-07-14 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new account of Euphorbia in southern Africa. Euphorbia is the second largest genus of plants in the world. Southern Africa enjoys a high diversity in Euphorbia and 170 species occur here naturally. Of these 170 species, 128 or 74% are endemic. Where most species of Euphorbia in the northern hemisphere are herbs or shrubs, most of those in southern African are succulent. These succulents range from small, almost geophytic forms where the tuber is larger than the above-ground parts to huge trees 6 to 15 m or more in height. Many of them are spiny. There are also small numbers of herbaceous species in southern Africa and many of these are also dealt with here. The last account of the succulent species for southern Africa was published in 1941 and much new data has accumulated since then. Our understanding of the relationships of the species in Euphorbia has also been greatly enhanced by recent analyses of DNA-data, which led to new and unexpected results. From this new information an entirely new classification was developed, in which Euphorbiawas divided into four subgenera. This provides the taxonomic framework for the presentation of our species here. Around ten new species have been described and these are presented in detail for the first time. This monograph is made up of two volumes. Volume 1 contains an extensive introductory chapter with an overview of the genus in the region, emphasizing many of its important and distinctive features. This is followed by Chapter 2, which deals with subgenus Athymalus. Of the four subgenera, this one is by far the most diverse in southern Africa, with 80 species. Volume 2 contains Chapters 3 (subg. Chamaesyce, 34 species), 4 (subg. Esula, 11 species) and 5 (subg. Euphorbia, 45 species), as well as an additional Chapter 6 covering the remarkable diversity of subg. Euphorbia in Moçambique. Each of Chapters 2 to 5 includes a key to all the species, followed by an account of each of them. This account includes synonymy, a description, data on distribution and habitat, line-drawings of floral features and other diagnostic details, notes on how the species is distinguished from its closest relatives and a brief history of its discovery. Several colour photographs are included for each species, illustrating its habitat, vegetative habit and flowering features, demonstrating key points distinguishing it from others and often showing its variability. Euphorbia is an important component of the vegetation in many of the drier parts of southern Africa. This book is based on a thorough evaluation of the vast herbarium record for southern African members of Euphorbia, on the extensive field-work conducted in the region and the wide taxonomic experience of the author. It is believed that both the professional botanist and the layman will find much that is new and informative in this monograph.

This book was released on 2012-07-24 with total page 779 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive guide to the ferns of southern Africa (covering South Africa, Swaziland, Lesotho, Botswana and Namibia) throws new light on a fascinating category of plants that is little known by the general public . User-friendly and accessible, it will enable quick and sure identification of all 321 ferns known to occur in the region. Each species features a double-page spread with a full plate of photographs (including close-ups); informative line drawings where necessary; clear text descriptions; tables that highlight differences between similar-looking species; and distribution maps based on years of intensive fieldwork. In addition, there are identification keys to families, genera and species. To compile this book the authors travelled extensively and took some 30 000 photographs, even finding several new species of fern. They are all treated in this guide – some described here for the first time. This unique and beautiful volume will become the standard reference book on the ferns of southern Africa.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive biographical guide to the scientific achievements, personal lives, and struggles of women scientists from around the globe. International Women in Science: A Bibliographical Dictionary to 1950 presents the enormous contributions of women outside North America in fields ranging from aviation to computer science to zoology. It provides fascinating profiles of nearly 400 women scientists, both renowned figures like Florence Nightingale and Marie Curie and women we should know better, like Rosalind Franklin, who, along with James Watson and Francis Crick, uncovered the structure of DNA. Students and researchers will see how the lives of these remarkable women unfolded, and how they made their place in fields often stubbornly guarded by men, overcoming everything from limited education and professional opportunities, to indifference, ridicule, and cultural prejudice, to outright hostility and discrimination. Included are a number of living scientists, many of whom provide insights into their lives and scientific times. Those contributions, plus additional previously unavailable material, make this a volume of unprecedented scope and richness.
