We are preparing text and images for our fifth annual magazine supplement. What started as a way to publish an article that was too big for a regular issue of ORCHIDS (Phil Spence’s detailed look at the Latouria section of Dendrobium) has become an eagerly anticipated bonus issue of the year. A separate publication gives us the opportunity to present a monograph to our members each year without compromising the general interest of the monthly issues. We continually strive to improve the quality of the supplement giving AOS members a valuable addition to their orchid libraries.

For the 2014 supplement we are fortunate to be able to give members a comprehensive overview of Stanhopea written by the acknowledged expert on the genus, Rudolf Jenny. Once again we appeal to our members for a small (or large) donation to underwrite the expense of the project. Your donation serves as a vote of confidence that you want us to continue producing an annual supplement. Please select "Annual Magazine Supplement" as donation type. Thank you.


Book Review:
Aerangis

By Isobyl la Croix. Hardcover with jacket, 200 pages, 156 color photographs and 10 line drawings, four maps, 386 line drawings. Timber Press, Portland, Oregon. $95.00. ISBN 978-1-60469-562-5 .

Elegantly simple. That is how we would describe it. Coffee-table books often lack the substance that a serious orchid grower wants, while scientific journals tend to contain taxonomic complexity that can bore, confuse and quickly lose the average reader. Isobyl la Croix has bridged that gap beautifully. Except for its size, Aerangis appears to be the former. It is a lovely book; artfully produced, including a bound ribbon book mark with a plethora of photographs, excellent graphics and layout. Upon closer inspection, the reader will immediately recognize that Isobyl has consolidated potentially confusing taxonomic information into an understandable format that is clearly organized, well written and a delight to read! Isobyl dedicated this work to her friend and colleague Joyce Stewart. Joyce had presented a monograph of the African species of Aerangis in 1979, but until now, information about the complete genus has been scattered between publications and has been incomplete. This book covers the 58 currently recognized species along with natural and man-made hybrids.

The book includes maps indicating native habitats of each species. Its six chapters are clearly laid out and contain a history of the genus including information on recent DNA work which will certainly change the genus in the future. It describes and illustrates the morphology and distinguishing features of Aerangis. And so importantly, it includes keys for identification. Isobyl has included a key to the entire genus since, as she states, "growers often don’t know the origin (in nature) of their plants". There are also separate keys for the African species and the Madagascar/Comoros species.

The chapter on habitat, climate and distribution includes many excellent photographs of the plants growing in situ. Isobyl covers important points about threats and conservation, stating that in nature the two biggest challenges for this genus is over-collection and the destruction of habitat. She gives insight to current conservation efforts and ex-situ propagation. The book contains an excellent overview of the cultivation of this genus, then within the well-presented “Plant Directory” (chapter 5) there is, in many cases, specific cultural information for each species. Isobyl has seen many of these plants first-hand in nature and is also an excellent grower, so this information will prove invaluable to readers.

The Plant Directory chapter will certainly be the most well-used one in the book. Isobyl has made this directory very simple to follow without the need to check the index each time you wish to look for a particular species. The photographs and drawings are excellent and plentiful (though more is always better, there must be a limit). There is excellent and useful information provided for every species. As growers who desire to acquire the “complete” collection of Aerangis, it’s interesting to see that nine species are represented only by drawings and/or photos of herbarium specimens illustrating the rarity of these plants.

The hybrids using Aerangis are also represented; it is a small chapter as there are relatively few. These hybrids can serve as a meaningful introduction for many people becoming interested in this genus as they tend to be easier to cultivate. Finally, there is a glossary and appendices to introduce and reinforce knowledge of botanical terminology.

This elegant book serves as both a consolidated botanical reference and a thoughtful introduction to this most special genera within the orchid family.

Q&A

Psychopsis papilio

We have a beautiful Psychopsis papilio that we have owned for more than four years. It has six beautiful spikes and some are in bloom. I am concerned that it needs repotting but I am afraid I could damage or kill the plant. When would it be best to repot and what are the signs that Pyp. papilio needs repotting?   — Celine Migyanka
