Book Description
This comprehensively updated and expanded edition of the region’s best-selling field guide to trees offers much, much more than the highly successful first edition. Fully updated text (including additional species entries) and distribution maps, numerous new photographs and a new 87-page section of full-tree photographs makes this well-loved guide even more indispensable in the field. Southern Africa has a rich variety of tree species, with an estimated 2 100 indigenous species and more than 100 naturalised aliens. 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.

Book Description
This Scientific Bibliography of the “Far Northern Drakensberg” is a continuation by the Afromontane Research Unit of the University of the Free State (ARU) to document published and other similar works on the mountains of the summer rainfall area of South Africa. It follows “A Scientific Bibliography of the Drakensberg, Maloti and Adjacent Lowlands” which was published in 2020 (Moffett 2020), and which covered the area between the North-Eastern Cape and the North-Eastern Free State. The current work extends this northward by including articles and publications dating back to 1875 (E.Cohen, on the Lydenburg goldfields) reaching as far as the Wolkberg and Woodbush near Tzaneen in Limpopo Province. Figure 1 shows the boundary of the area covered, and although referred to as the Far Northern Drakensberg in this work, it is identical to that described as the LMEE, Limpopo, Mpumalanga & Eswatini Escarpment by Clarke et al (2022). Although slightly separate from the “lower” escarpment, the mountainous Barberton and adjacent Eswatini area, as well as the Leolo Mountains in eastern Sekhukhuneland are also included. Details on how the boundary in figure 1 was determined are given in Clark et al (2022). Bibliographies on two further ranges in the summer rainfall area, viz. the Magaliesberg in Gauteng province and the Soutpansberg in Limpopo province are to be the subject of future compilations.

Book Description
This encyclopedia offers access to the diversity of ferns and seed plants, the most important groups of green land plants. Available information of general and systematic relevance is synthesized at the level of families. Evidence from virtually all disciplines important to modern taxonomy makes the work a most valuable source of reference not only for taxonomists, but for all who are interested in the various aspects of plant diversity. A revised classification includes a complete inventory of genera along with their diagnostic features, keys for identification, and references to the literature. The first volume deals with pteridophytes and gymnosperms.

Book Description
Only a bunch of heavily armed gardeners can save the world's most valuable plant. A priceless plant, a rare African cycad thought to be extinct and prized by collectors, has been discovered, then stolen. Joanne Flack, widowed and broke, is the prime suspect for the crime. While supposedly hiding out in London she single-handedly foils a terrorist plot, killing a lone-wolf gunman. Former mercenary turned CIA contractor, Sonja Kurtz, uncovers a link between the missing plant and the terrorist who tried to kill Joanne. The US Government thinks that if it can find the missing cycad it can foil an attack to rival 9-11. Hot on Joanne’s trail is retired US Fisheries and Wildlife Department special agent Rod Cavanagh who knows his plants and knows his target – he’s her former lover. Joanne is a member of the Pretoria Cycad and Firearms Appreciation Society. She, Sonja and Rod enlist the help of this group of ageing gardeners and gun nuts to find a plant worth a fortune and the traitor in their midst who is willing to kill for it.

Book Description
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.
