Ferns of Southern Africa: A Comprehensive Guide (PVC)
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.
Field Guide to Succulents of Southern Africa
Southern Africa is the natural home of the richest and most diverse succulent flora in the world. These plants come in all shapes and sizes, from trees such as the baobab at more than 20 m tall, to miniature soil huggers, just a few millimetres high, which mimic their pebble-desert surroundings. This user-friendly, richly illustrated field guide features more than 700 southern African succulents, focusing on the most interesting and commonly encountered species. An introduction to families and their key features will help readers identify the relevant plant group, while concise accounts describing the plants’ diagnostic features, along with distribution maps, will enable quick ID of species. More than just an ID guide for plant lovers, this book will inspire gardeners who are turning to indigenous, low-maintenance and waterwise plants for cultivation.
