An authoritative treatise on the history of botanical studies and exploration in Angola. For any region, cataloging, interpreting, and understanding the history of botanical exploration and plant collecting, and the preserved specimens that were amassed as a result, are critically important for research and conservation. In this book, published in cooperation with the International Association for Plant Taxonomy, Estrela Figueiredo and Gideon F. Smith, both botanists with expertise in the taxonomy of African plants, provide the first comprehensive, contextualized account of plant collecting in Angola, a large country in south-tropical Africa. An essential book for anyone concerned with the biodiversity and history of Africa, this authoritative work offers insights into the lives, times, and endeavors of 358 collectors. In addition, the authors present analyses of the records that accompanied the collectors’ preserved specimens. Illustrated in color throughout, the book fills a large gap in the current knowledge of the botanical and exploration history of Africa.

The 18th century witnessed a new interest in African animals. Research was undertaken at the Cape of Good Hope by explorers whose books, manuscripts and drawings concerning mammals and birds are listed and discussed within this text.;This text gives details on four collections of 300 mammal and bird drawings connected with Levaillant's research. Many examples are illustrated. The zoological contents of the material left by these seven explorers are analyzed for all mammals and birds emphasizing the history, taxonomy, nomenclature and zoogeography.

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 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.

Southern Africa is home to more than 2,000 introduced (not indigenous) trees. These non-native species are encountered daily and form a familiar part of our urban landscapes, growing successfully in parks, gardens, along road sides, and in other open spaces. This guide features nearly 600 of the most common and familiar of these and, using the same model of identification as FG Trees of Southern Africa, facilitates ID based on leaf and stem features. The book provides the country of origin for each species and offers key information on cultivation and uses. Each entry is supported by colour images that depict key features, and a shaded map that shows the plant’s cold tolerance (where the species can grow). An essential guide for landscapers and gardeners as well as tree enthusiasts who will struggle to find these trees in their guide to indigenous trees.
