A Field Guide, Third enlarged edition
This field guide of the wildflowers in the Azores islands provides short species portraits with full- colour photographs for 645 vascular plants growing wild in the archipelago and mentions key distinguishing characters for the remaining species. More than 1100 of the about 1200 species of the flora of the Azores are covered in this book, the most comprehensive treatment for these islands. Not only the most common species but also rare and unusual plants of thrilling beauty are illustrated and described, some of them for the first time.
Much emphasis is given to endemic species that can be found nowhere else in the world and invasive plant species that have been introduced to the Azores from all over the globe. They describe a serious threat to the native ecosystems in the archipelago. In addition to the scientific name, the Portuguese, English, German, and French names are given for each species. A glossary in English, Portuguese and German helps readers to better understand the scientific terminology.
An invaluable aid for all plant lovers in the Azores: students, teachers, farmers, rangers, scientists, tourists.

Institutional Arrangements and Performance
Smallholder agricultural markets in the majority of Sub-Saharan Africa are liberalized to enhance market linkages and efficiency. However, the result of the private sector response has been disappointing, especially in areas with constrained market infrastructure. Coordination problems and high transaction costs have considerably constrained market functioning. To reduce these costs, new institutional innovations such as the strengthening of collective marketing groups to improve the performance of rural contractual arrangements would be required. This could be the rationale behind similar institutional innovations in Camel milk enterprise in Kenya where contractual arrangements are married with collective action at market intermediation to rival individual trade relationships. However, the mere presence of these innovations may not automatically assure that those trade relationships are efficient. This could be true for the camel milk trade where farmers continue to face relatively high trans- action costs that denies them the opportunity to tap the gains from the growing demand in the local and international market despite such interventions. This book seeks to establish the appropriateness of a higher degree of coordination in economizing transaction costs with a focus on how the alternative institutional arrangements in camel milk marketing compare based on transaction cost and the extent to which variation in these arrangements can be explained by product characteristics, market requirements, and the market structure. The focus is also on the scope for improvements and the parties and cost attributes necessary to make the institutional arrangements feasible as transaction cost reduction mechanism. The analytical framework is based on the transaction cost approach combined with a modelling assessment for simulation of organization forms under the existing market conditions. The book identifies transport and information costs as important transactions and marketing costs that influence milk transactions through the trader cooperative. The evidence of presence of increasing returns to scale is detected indicating the scope for efficiency improvement. Milk allocation and revenues from trade can therefore be significantly increased by enhancing the efficiency of the existing collective efforts among camel milk traders. However, such transaction costs reduction interventions at the farmer level would not however achieve any meaningful improvement in volume transacted through trader cooperatives and incomes unless accompanied by an improved procurement price. This calls for support for agricultural market information, improvement of road infrastructure and streamlining storage and transportation.<

The Flore du Gabon series provides access to the information on the great botanical wealth of this central African country, reputedly harbouring the richest lowland rain forest in Africa. With 12.5% of all plant species being endemic to the country and some 85% of its surface being covered with a highly diverse lowland rain forest, Gabon is a botanical paradise and hotspot. Over 10% of its surface is under protection, which renders this country a Mecca for conservationists, ecotourism and scientists. For an effective conservation management, but also to support a wise and sustainable use of this unique diversity, it is essential to be able to simply identify the plants that play such an important role, be it as food for gorillas, birds, etc., as medicine, nutrition or timber, or just as one of these essential elements of the ecological network. The Flore du Gabon provides this essential tool for reliable identification, its editorial team making sure the identification keys are simple and straightforward, descriptions having diagnostic features stand out in bold, and clarifying illustrations. As such, it hopes to assist researchers, foresters, conservationists, amateur botanists and policy makers alike and to contribute to the survival of Gabon’s unique biodiversity.
The Flore du Gabon series was started in 1961 by the Muséum national d’Histoire naturelle (MNHN) in Paris and until 2004 no less than 37 volumes were published dealing with about 80 families and over 2200 species. In 2006, the Wageningen branch of the National Herbarium of the Netherlands (NHN), now part of Naturalis Biodiversity Center, who had built up their knowledge on the Gabonese flora for over 35 years, continued its production. From 2014 onwards, the series was continued jointly by Meise Botanic Garden and Naturalis. End of 2022, over 3900 species have been dealt with, while around 700 await their treatment.
For this final challenge, additional funding was obtained from the Alberta Mennega Foundation. This should render it feasible to produce two or three volumes each year and finish the Flore du Gabon series by 2025.
