| cycads of south africa cynthia giddy: The Cycad Botanists Roy Osborne, Dennis Wm Stevenson, 2025-03-25 This work provides short biographies of 50 historical figures in cycad biology. It covers those starting in the early 17th century through the 21st century. Each of the biographies covers a career including birth and death, schooling, places of employment, travel in field work, publications, place of their cycad type specimens, list of species described and list of species named for them. The latter two items are illustrated along with any honorific items such as currency, stamps, and so on. Additionally, each entry has a portrait. The purpose of this work is to bring together in one place treatments on the lives, work, publications, illustrations, and type specimens of the historic figures in cycad biology. It will be of interest to researchers in cycads but also to the large, amateur community of cycad enthusiasts and others interested in gymnosperms and the history of botany. The book will be featured at the triennial meetings on cycad biology at New York Botanical Garden. |
| cycads of south africa cynthia giddy: Cycads of South Africa Cynthia Giddy, 1984 This book, now in its second edition, is the result of years of study and of trips to see and photograph cycads in their natural habitat. Each of the 29 South African species is described in terms of stem, leaves, seeds and cones. Each description is accompanied by a colour plate showing details of male cones, female cones, leaves and plants in their natural environment...--Book jacket. |

| cycads of south africa cynthia giddy: Cycads John Sydney Donaldson, 2003 The IUCN/SSC Cycad ACtion Plan brings together the best available information on this ancient and fascinating group of plants. Cycads were a dominant part of the earth's flora during the age of the dinosaurs and many species were common even in more recent times. However, many of the 297 species and subspecies dealt with in the Cycad Action Plan have been badly affected by habitat destruction and plant collecting within the last century. As a result, more than half the known species are now classified as threatened, and the cycads stand out as one of the most threatened groups of plants in this world.The Action Plan provides an overview of all the cycads and the threats to their survival. This is followed by separate assessments for the four broad regions where cycads now occur, namely Africa and the Indian Ocean Islands, Australia, Asia, and the New World. Trade in cycads has had a substantial impact on wild cycad populations and there is a separate chapter on trade and the effectiveness of control measures such as CITES. In addition, with so many species facing extinction in the wild, garden collections have become increasingly important and we have assessed the global status of cycad collections.Finally, the Cycad Action Plan presents a set of objectives and actions to reduce the threat to cycads in the wild and to provide ex situ conservation for those that almost certainly will become extinct in the wild. Wherever possible, we have tried to identify and build on innovative projects, such as community-based nurseries, and to link cycad consideration with other global and local initiatives such as the conservation of biodiversity hotspots. |

| cycads of south africa cynthia giddy: Lulu Phezulu Leigh Voigt, 1999 Lulu Phezulu (or 'Lulu on top') is the name of the home of Leigh ('Lulu') Voigt, the well-known artist and book illustrator who lives with her artist husband in the house they built for themselves on a mountain top in a nature reserve in Mpumalanga. This treasure of a book is at one level a personal account of her and her family's move from the city to the country and their serendipitous encounters with nature and the local people. It is also a breathtakingly beautiful natural history notebook filled with Leigh's watercolours and drawings as well as a wealth of anecdotes, curiosities, lore, and legend about the natural world. Lulu Phezulu has grown over many years out of Leigh's need to express, in both words and pictures, the bush and its fascination, highlighting the oddities and complexities of some of its engaging characters, both human and animal. It will appeal to all who have a love of nature and a love of life, both the ordinary and the extraordinary. |

It includes the names of some 33,000 plant species determined to be rare or threatened on a global scale. Conservation assessments were provided by the IUCN Species Survival Commission, the National Botanical Institute (South Africa), Environment Australia, and CSIRO, The Nature Conservancy, the Smithsonian Institution, and the Royal Botanic Gardens, Kew, together with hundreds of botanic gardens and botanists throughout the world. The Royal Botanic Gardens Edinburgh and the New York Botanical Garden have made major in-kind contributions.The result of 20 years work by botanists and conservationists around the world, it is intended as a conservation tool, a provider of baseline information to measure conservation progress and as a primary source of data on plant species. Most importantly, however, it provides the building blocks on which to base a worldwide effort to conserve plant species. |
