Book Description
This open access multi-authored book presents a 'state of the science' synthesis of knowledge on the biodiversity of Angola, based on sources in peer-reviewed journals, in books and where appropriate, unpublished official reports. The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems are still very poorly researched and documented. This 'state of the science' synthesis is for the use of all students of Angola's biodiversity, and for those responsible for the planning, development and sustainable management of the country's living resources. The volume brings together the results of expeditions and research undertaken in Angola since the late eighteenth century, with emphasis on work conducted in the four decades since Angola's independence in 1975. The individual chapters have been written by leaders in their fields, and reviewed by peers familiar with the region.

Book Description
Biosystematic studies on the Rubiaceae have a long tradition at the Institute of Botany in Vienna. Within this family the Anthospermeae, and especially its African and Madagascan members, are of particular interest because of several aspects in their evolution: I) Perfection of anemophily within an otherwise nearly exclusively zoophilous family; 2) transitions from hermaphrodity to polygamy and finally dioecy; 3) differentiation from large and long-lived shrubs to short-lived herbs; 4) adaptive radiation from humid to seasonally dry, fire-exposed and xeric habitats. However, morphological diversity linked to sexual differentia tion, modificatory plasticity, and eco-geographical polymorphism have for a long time hampered our understanding of the relationships among these African Anthospermeae. Thus, it was imperative to put special emphasis on field observations and to carry out a variety of experiments with cultivated plants in addition to the analysis of an enormous herbarium material. The author, for this reason, carried out extensive field work, often under very adverse conditions, and covered most African countries from Ethiopia to Southern Africa and twice visited Madagascar. In this way a multitude of data was accumulated on the group in respect to germination and growth form, vegetative and reproductive morphology, anatomy and biology, embryology, karyology, crossing relationships, phytochemistry, distribu tion and ecology, etc.

Book Description
This volume reproduces key historical texts concerning `colonial knowledges’. The use of the adjective 'colonial' indicates that knowledge is shaped by power relationships, while the use of the plural form, ’knowledges’ indicates the emphasis in this collection is on an interplay between different, often competing, cognitive systems. George Balandier’s notion of the colonial situation is an organising principle that runs throughout the volume, and there are four sub-themes: language and texts, categorical knowledge, the circulation of knowledge and indigenous knowledge. The volume is designed to introduce students to a range of important interventions which speak to each other today, even if they were not intended to do so when first published. An introductory essay links the themes together and explains the significance of the individual articles.

Book Description
Over the past four centuries botanists and gardeners in the British Isles have gathered, maintained and propagated many varying species of plants. Their work has been documented in innumerable books and articles which are often difficult to trace. The Dictionary of British and Irish Botanists and Horticulturalists represents a time-saving reference source for those who wish to discover more about the lives and achievements of the horticulturalists listed. The dictionary's utility comes not only from indicating the major publications of the named authors, but also the location of their herbaria and manuscripts.; The previous 1977 edition of the Dictionary has for many years been a much used source of information for botanists, botanic artists and archivists. In this revised edition the scope has been expanded to include among its 13,000 entries flower painters in addition to botanical artists over 1400 entries and, for the first time, garden designers.; Finally the Dictionary should have international appeal since so many botanists and gardeners worked on collective plants overseas, in particular in North America and the British Commonwealth.; Each entry gives, wherever possible, details of dates and places of birth and death, educational qualifications, professional posts, honours and awards, publications, location of plant collections, manuscripts, drawings and portraits. Its main function, however, is to provide further biographical references to books and periodicals. Comprehensive classified indices facilitate access by professions and activities, countries, and plant interests.

Book Description
This is the only comprehensive account of all eight species in the genus Adansonia. It describes the historical background from the late Roman period to the present. It covers the extraordinary variety of economic uses of baobabs. There are also appendices on vernacular names, gazetteer, economics, nutrition and forest mensuration. This book fills a gap in the botanical literature. It deals with a genus that has fascinated and intrigued scientists and lay persons for centuries.
