Excerpt from Plants and Their Ways in South Africa For several reasons it has seemed desirable to extend the first edition of this book into a second, and in doing so additions have been made, in some cases with considerable reluctance. Not that the first edition was by any means regarded as complete. The book was first written with a view of attracting young eyes to objects of interest in the plant world that could be enjoyed without the use of a compound microscope. In a measure the object was attained, at least sufficiently to show that a microscope was by no means indispensable for students beginning to observe plant life. When contemplating revision, suggestions were asked of young teachers, and some of them seemed to find the lack of a lesson on internal anatomy-one of the disadvantages of the former edition. In order to meet their needs a short lesson on this subject has been added, together with a more extended synopsis of the Natural Orders of South African plants. While these additions appear somewhat as excrescences to the more elementary chapters of the book, the hope is entertained that their usefulness to those for whom they have been written will justify their insertion. It is a pleasure to acknowledge gratefully my indebtedness to those who have aided me in the work of revision. Miss Alette Hugo and Miss Avrylle Bottomley have given valued assistance in pen-and-ink drawings. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

A guide of the most commonly used and best known SA medicinal plants including their botany, traditional uses and active ingredients
For over a century, plant specialists worldwide have sought to transform healing plants in African countries into pharmaceuticals. And for equally as long, conflicts over these medicinal plants have endured, from stolen recipes and toxic tonics to unfulfilled promises of laboratory equipment and usurped personal patents. In Bitter Roots, Abena Dove Osseo-Asare draws on publicly available records and extensive interviews with scientists and healers in Ghana, Madagascar, and South Africa to interpret how African scientists and healers, rural communities, and drug companies—including Pfizer, Bristol-Myers Squibb, and Unilever—have sought since the 1880s to develop drugs from Africa’s medicinal plants. Osseo-Asare recalls the efforts to transform six plants into pharmaceuticals: rosy periwinkle, Asiatic pennywort, grains of paradise, Strophanthus, Cryptolepis, and Hoodia. Through the stories of each plant, she shows that herbal medicine and pharmaceutical chemistry have simultaneous and overlapping histories that cross geographic boundaries. At the same time, Osseo-Asare sheds new light on how various interests have tried to manage the rights to these healing plants and probes the challenges associated with assigning ownership to plants and their biochemical components. A fascinating examination of the history of medicine in colonial and postcolonial Africa, Bitter Roots will be indispensable for scholars of Africa; historians interested in medicine, biochemistry, and society; and policy makers concerned with drug access and patent rights.

Field Guide to Trees of Southern Africa describes and illustrates more than 1 000 of these, focusing on trees that are the most common and most likely to be encountered. Species are logically arranged in 43 groups based on easy-to-observe leaf and stem features, and each account is illustrated by full-colour photographs of the plant’s diagnostic parts. The text also touches on the practical uses of the plants.
