For the IOS it was an honour and a great privilege to hold for the third time our traditional Congress at the Desert Botanical Garden. Previous Congresses were held in 1992 and 2002, and 2014 is a sig - nificant date for the Garden, as it marks the 75th Anniversary of its foundation. This Congress, like the previous ones organized at the DBG, were extremely well organized and, as always, provided an excellent opportunity for positive interaction among people interested on the study and conservation of succulent plants. As indicated in the Program reproduced here, the Congress included a keynote speaker, oral and poster presentations, exhibits of botanical art and bonsai, and a fieldtrip to the Grand Canyon. In addition, a tour to the remarkable collection of the Wallace Desert Gardens was organized. The Desert Botanical Garden and IOS are very closely related organizations because their goals are highly convergent. For several decades, both organizations have been working towards the same purpose: to advance in research and conservation of succulent plants. On behalf of the Executive Board, I would like to express our thanks and appreciation to Mr Kenneth Schutz, Executive Director of the Desert Botanical Garden, for making available to the Congress the Garden's facilities and amenities. Also, special thanks to Raul Puente, Andrew Salywon, Wendy Hodgson, Christina Carlson, and members of Garden's staff and volunteers for taking care of all the details of the organization of the Congress. Over the last few years, the IOS Board was under severe tension as a consequence of unfounded criticism of the IOS management, emitted by a member of the Board. As a result, the Board turned nearly dysfunctional during several months before the Congress and the situation caused considerable confusion among the membership. Fortunately, however, the current Board for the 2014–16 biennium has changed composition and normal conditions have already been restored for a constructive environment and positive interaction. The current IOS Board is in the best disposition to work towards the fulfilment of the substantive goals of our organization: to promote the study and conservation of succulent and allied plants and to encourage international collaboration amongst those interested in them. Due to the fact that most members of the IOS Board were not able to attend the Congress, there was not a quorum for the customary meeting of the Board. Consequently, arrangements have already been made to hold a meeting of the new Board on 26 September 2014, at the Museum of Natural History in Paris, France. Héctor M.
