Namaqualand is justifiably famous for the floral wonderland it becomes in spring, when seas of bright flowers carpet the land. Astonishingly, the carpet comprises some 3,800 species, of which 28% are endemic. This book introduces nearly 600 species, highlighting those most commonly found, most conspicuous, spectacular or interesting, as well as endemics. An introduction touches on the species selection for the book, the climatic and topographical subregions within Namaqualand, plant names and uses, and conservation issues. The concise species descriptions also give seed and fruit details, uses, local growing conditions and flowering times, along with beautiful full-colour photographs. This is a must-have guide for visitors to Namaqualand, or for anyone interested in the wild flowers of southern Africa.

How to use woody herbs to grow mature bonsai in one year or less. This practical guide provides tips on training, caring, and decorating.
This book marshals ecological literature from the last century on facilitation to make the case against the widely accepted individualistic notion of community organization. It examines the idea that positive interactions are more prevalent in physically stressful conditions. Coverage also includes species specificity in facilitative interactions, indirect facilitative interactions, and potential evolutionary aspects of positive interactions.
Flowers are the beautiful and complex reproductive structures of the angiosperms, one of the most diverse and successful groups of living organisms. The underlying thesis of this book is that to fully understand plant development (and why flowers differ in shape, structure and colour), it is necessary to understand why it is advantageous for them to look like they do. Conversely, in order to fully understand plant ecology, it is necessary to appreciate how floral structures have developed and evolved. Uniquely, this book addresses flowers and flowering from both a molecular genetic perspective (considering flower induction, development and self-incompatibility) and an ecological perspective (looking at the selective pressures placed on plants by pollinators, and the consequences for animal-plant co-evolution). Understanding Flowers and Flowering, the first edition of which won BES Marsh Book of the Year in 2009, begins by considering the evolution of flowers and the history of research into their development. This is followed by a detailed description of the processes which lead to flower production in model plants. The book then examines how flowers differ in shape, structure and colour, and how these differences are generated. Finally it assesses the role of these various aspects of floral biology in attracting pollinators and ensuring successful reproduction. This new edition has been completely revised and updated to reflect the latest advances in the field, especially an increased understanding of the evolution of floral traits. New chapters consider the genetic basis of the floral transition in diverse species, as well as the evolutionary lability of floral form. There is a new focus throughout on both phylogenetic position and morphological diversity across the angiosperm phylogeny. Understanding Flowers and Flowering continues to provide the first truly integrated study of the topic - one that discusses both the how and why of flowering plant reproductive biology.
Among the major challenges facing society today, seeking renewable alternatives to petroleum-based fuels and manufactured goods is critically important to reducing society’s dependency on petroleum and tackling environmental issues associated with petroleum use. In recent years there has been considerable research targeted toward the development of plant-derived bioproducts to replace petrochemical feedstocks for both fuel and manufacturing. Plants not only provide a large amount of renewable biomass, but their biochemical diversity also offers many chemical and molecular tools for the production of new products through biotechnology. Plant Bioproducts is an introduction to the production and application of plant bioproducts, including biofuels, bioplastics, and biochemicals for the manufacturing sector. Contributing authors examine various bioproducts with respect to their basic chemistry, relationship to current petrochemical-based products, and strategies for their production in plants. Chapters cover the integrated roles of agronomy, plant breeding, biotechnology, and biorefining in the context of bioproduct development. Environmental, economic, ethical, and social issues surrounding bioproducts, including the use of genetically modified crops, challenges to food security, and consumer acceptance, are also covered.
