This guide and corresponding checklist is a work in progress. We invite others, particularly taxonomic experts within the region, to partner with us to get information about the region's flora on the Web. For each species our goal is to put high-quality images, identification characters, maps, and text on the Web. This project is part of Plants for the People. Please see Discover Life's prospectus for an overview of our goals and technology.

We gathered information for this project from numerous sources, most notably:

• Tropicos database, Missouri Botanical Garden
• Instituto Nacional de Biodiversidad, Costa Rica (INBio)
• National Museum of Natural History, Smithsonian
• Center for Tropical Forest Science, Panama
• Smithsonian Tropical Research Institute, Panama
