「Internet Encyclopedia of Panamanian wild orchids」 COSPA made the encyclopedia of CD’ROM in 2003 by the assistance of many members concerned in COSPA. In this occasion, we decide to publish the new version by web with some corrections and addition of new photos. In the previous version, photos taken by Koichiro Akechi and Fuzuki Miura were used. After the publication of previous one, many photos taken by Mitsunao Hyoudo and other members. Therefor in this edition those photos are added. Recently there are some names of the genus or species of wild orchids changed. For example, the orchid genus Cattleya distributed in Panama and some other Central American countries which have two leaves are on a bulb transferred to genus Guarianthe. In this edition we also looked such points. This new project was promoted by Koichiro Akechi, Mitsunao Hyodo and Manabu Honma and web editing done by Natsumi Suyama. One of important executors, Fuzuki Miura passed in Panama where she deeply appreciated January, 2006. We express our sincere condolence on the loss of her. We hope the better understanding of wild orchids of Panama leadsthe promotion of the activities for conservation of plants faced to the risk of extinction. We express sincere thanks to the members of APROVACA and COSPA who cooperate to us for this Internet Encyclopedia of Panamanian wild orchid. COSPA
