Renziana

Orchid journal published by the Swiss Orchid Foundation

The Swiss Orchid Foundation annually publishes the Renziana, a bilingual (English and German) orchid journal of around 100 pages, which is developed in collaboration with renowned scientists, growers and enthusiasts. In each issue, different aspects of a genus are highlighted, such as the morphology, taxonomy, geographical distribution, ecology, history, conservation, cultivation and breeding of the plants. Probably the most interesting part for our readers is the chapter about the current taxonomy, where the classification of the plants according to the latest scientific results is shown, and each species of the genus is illustrated with a high quality colour photograph. In addition, you will find stunning pictures of the plants' natural habitat, of hand-coloured drawings from historic books, of hybrids, and detailed distribution maps. A distinctive feature of our journal is that almost all of these pictures can be downloaded from the website of the Swiss Orchid Foundation. It is very easy to find the favoured image, since each picture has a unique ID-number, which is shown in the caption. The ID-number simply has to be typed in the search form of the World Orchid Iconography database and you will automatically be forwarded to the corresponding webpage.

The journal can directly be ordered on this website. Payment is made either by PayPal, credit card, or in a classic bank transfer. If you would like to retrieve your copy personally in Basel and save the postage or if you have any questions about mail order, don't hesitate to contact us: orchid@unibas.ch

The Renziana is now also available as an ebook on Google play. Here you also have the possibility to take a look at the first 20 pages of each issue for free!

Renziana V - Coryanthes

The fifth Renziana deals with the Genus Coryanthes. Gunter Gerlach is the author of this comprehensive review of the tropical American bucket orchids (Coryanthes): their classification, biology, pollination and cultivation. Each species is illustrated with beautiful colour photographs. They are amongst the strangest of all orchids with complex hanging flowers. The elaborate pollination mechanism of these unusual flowers has already attracted the attention of Charles Darwin in his seminal book On the Various Contrivances by which British and Foreign Orchids are Fertilised (1862: John Murray, London).
Coryanthes plants have an amazing life cycle which is described in the new Renziana in detail. The plants have a symbiosis with ants that form a nest in the roots. The ants protect the plant from predators and provide nutrients that the roots of the orchids can take up. This has consequences for gardeners trying to cultivate these spectacular orchids.
Gerlach has devoted many years to the study of Coryanthes and knows these orchids intimately from his field studies in Central and South America and his research in München.
They can be immensely rewarding subjects for the horticulturist with their exotic, flamboyant, fragrant and downright strange flowers. We hope the accounts of one of nature’s wonders will inspire readers to follow in Gunter Gerlach’s footsteps, at least in their greenhouse if not in the wild - grow bucket orchids and be truly amazed by them!

Renziana IV - Cattleya

The fourth Renziana issue deals with the Neotropical genus Cattleya. Due to their large impressive flowers with golden and royal purple painted lips, cattleyas were highly desired during Victorian times and ranked among the first orchids that were cultivated in the nurseries of the English orchid growers. This has not changed until today - for many orchid enthusiasts these plants still belong to the classics of an orchid collection. In the current issue, we follow our tradition to provide an elaborated classification of the plants with excellent high quality images. Cássio van den Berg, the world's leading Cattleya-specialist presents the recently published classification of the genus and explains, why he included Sophronitis and Hadrolaelia into Cattleya. Besides taxonomy, you will find lots of additional information about the plants and helpful tips. Join us on a country tour through Brazil, where you will get unique impressions of the natural habitats. Who is pollinating cattleyas, why do natural hybrids exist and which role do they play for the development of new species? Read about scientists, orchid hunters and orchid growers and learn about how they contributed to taxonomic confusion in the genus. Finally we have a look at the outcome of a breeders work and listen to the recommendations of an orchid grower. We promise you will not regret to have acquired the current Renziana!

    Renziana III - Vanda

    The third Renziana issue is devoted to Vanda, a genus of about 73 species that can boast spectacular large, flat and brightly coloured disc-like flowers. As it is known for Renziana, this issue will provide a complete iconography of the genus Vanda on more than 110 high quality photographs, based on the recent re-assessment of its generic delimitation. Additionally, this issue provides lots of information, from the basic biology and ecology of the genus to historical information about its discovery and introduction to expert tips on how to grow and hybridise vandas. We trust that those already growing vandas will find fresh information in this issue of Renziana to assist their work and those who have yet to grow them will be inspired to do so. Now available!

    Renziana II - Phalaenopsis

    The second Renziana issue is devoted to the orchid genus Phalaenopsis. Over the last decades, Phalaenopsis have become the most popular commercial orchids and houseplants decorating thousands of windowsills. Renziana readers will find professional advice for cultivation at home and commercial nurseries give insights of their artificial propagation methods. Like the first issue, Renziana illustrates the magnificent flowers of all wild species with colour images, supplemented by habitat photographs and information on the geographical distribution of the genus. In addition, an overview of the numerous natural and artificial hybrids is given. Finally, the importance of species protection in natural habitats that are more and more reduced also for Phalaenopsis is emphasized.

    Orchids from Europe, Asia Minor and North Africa

    On occasion of the exhibition of orchids from Europe, Asia Minor and North Africa this brochure was published. Besides numerous pictures of marvellous orchids, the focus of this journal is an introduction to Jany Renz' legacy, which consists of a herbarium, a literature- and a slide collection. In several contributions, the history of the collection is highlighted, beginning with the life of Dr. Jany Renz and his passion for orchids, up to the formation of the Swiss Orchid Foundation and the presentation of its activities.
