This book’s title says it all! Now in an updated second edition, it provides a clear understanding of how trees are constructed and what to look for when identifying a tree.

The book is divided into two parts: Part 1 describes and clearly illustrates the different parts of a tree and their role in tree identification. Part 2 features a key to 43 tree groups, based on easy-to-observe stem and leaf features. It carefully outlines each group and the southern African tree families represented in the different groups. Numerous colour photographs and explanatory illustrations support the text, making this an accessible and easy-to-use guide.

How To Identify Trees In Southern Africa will equip readers with a sound understanding of how trees work and what to look for in order to make a positive ID.

This fully updated edition of Field Guide to Wild Flowers of South Africa covers more than 1,100 species of flora, focusing on the most common, conspicuous and ‘showy’ plants around the region.

An informative introduction discusses plant diversity, vegetation types, and includes a key to identifying plant groups. The species descriptions follow and each is accompanied by:

• a vivid photograph,
• a distribution map showing range, and
• an indication of the plant’s flowering season.

This invaluable, up-to-date guide provides the tools and information needed to identify flowering plants across South Africa.

A refreshing new book on mushrooms and other fungi in South Africa, covering 200 species - more than any mushroom book in the region to date. Text covers each species' distribution (both regionally and worldwide), description, typical habitat, edibility and toxicity. Magnificent photographs accompany each species, making this both a practical guide and a beautiful book. It will be welcomed by all mushroom enthusiasts, and by nature-lovers in general.

Africa has been and continues to be a significant source of medicinal and aromatic plants and botanicals to the world's food, drug, herb and dietary supplement market, and in the past decade numerous African plant materials have established a strong international market presence. This book provides an excellent opportunity to delve into the current and future contributions that African plants can and will continue to make both internal to Africa and on the global stage. This book expertly covers various medicinal plants of African origin and the some of the latest basic and clinical research supporting their ongoing and potential uses in self-care and healthcare. This work also examines various issues and trends in medicinal plants from their uses in Traditional Medicine and ethnobotany, to our modern understanding of the plants chemistry and pharmacognosy, natural products chemistry and applications of medicinal plants, quality control, and models of benefit sharing.

Viruses that infect plants are responsible for reduction in both yield and quality of crops around the world, and thus are of great economic importance. This has provided the impetus for the extensive research into the molecular and cellular biology of these pathogens and into their interaction with their plant hosts and their vectors. However, interest in plant viruses extends beyond their ability to damage crops. Many plant viruses - for example, tobacco mosaic virus - have been used as model systems to provide basic understanding of how viruses express genes and replicate. Others permitted the elucidation of the processes underlying RNA silencing, now recognized as a core epigenetic mechanism underpinning numerous areas of biology. This book attests to the huge diversity of research in plant molecular virology. Written by world authorities in the field, the book opens with two chapters on the translation and replication of viral RNA. Following chapters cover topics such as viral movement within and between plants, plant responses to viral infection, antiviral control measures, virus evolution, and newly emerging plant viruses. The book concludes with two chapters on biotechnological applications of plant viruses. Throughout, the focus is on the most recent, cutting-edge research, making this book essential reading for everyone working with plant viruses.

Although the problem of controlling the spread of exotic invasive plant and animal species in the United States has been recognized for quite some time, it has been lacking an adequate legislative mandate, public awareness, and sufficient funding to meet the challenge. This ACS Symposium Series title showcases the many diverse efforts being made to control invasive species at the federal, state, and local levels. It recognizes the global extent of the problem and compares the methods used in other countries with those of the U.S., and includes recommendations of how best to proceed from here.

In this book Adrian Koopman details the complex relationship between plants, the Zulu language and Zulu culture. Zulu plant names do not just identify plants, they tell us a lot more about the plant, or how it is perceived or used in Zulu culture. For example, the plant name umhlulambazo (what defeats the axe’ tells us that this is a tree with hard, dense wood, and that usondelangange (come closer so I can embrace you) is a tree with large thorns that snag the passer-by. In a similar vein, both umakuphole (let it cool down) and icishamlilo (put out the fire) refer to plants that are used medicinally to treat fevers and inflammations. Plants used as the base of love-charms have names that are particularly colourful, such as unginakile (she has noticed me), uvelabahleke (appear and they smile) and the wonderfully named ungcingci-wafika-umntakwethu (how happy I am that you have arrived, my sweetheart!). And then there are those plant names that are just plain intriguing, if not mystifying: umakhandakansele (the heads of Mr Ratel), isandlasonwabu (hand of a chameleon), intombikayibhinci (the girl does not wear clothes) and ukhuningomile (piece of firewood, I am thirsty).

Andre Laurendeau was the most widely respected French-Canadian nationalist of his generation. The story of his life is to a striking degree also the story of French-Canadian nationalism from the 1930s to the 1960s, that period of massive societal change when Quebec evolved from a traditional to a modern society. The most insightful intellectual voice of the nationalist movement, he was at the tumultuous centre of events as a young separatist in the 1930s; an anti-conscription activist and reform-minded provincial politician in the 1940s; and an influential journalist, editor of the Montreal daily Le Devoir, in the 1950s. At the same time he played an important role in Quebec's cultural life both as a novelist and playwright and as a well-known radio and television personality. In tracing his life story, this biography sheds indispensable light not only on the development of Laurendeau's own nationalist thought, but on his people's continuing struggle to preserve the national values that make them distinct.
