Although this tool is primarily built upon content in the Family Guide for Fruits and Seeds, resources from the Federal Noxious Weed Disseminules of the United States and Table Grape Weed Disseminule ID were also incorporated. We thank the authors of these tools and their collaborators. We are grateful to the International Seed Morphology Association for providing illustrations for the key and glossary, the Canadian Food Inspection Agency and South Australian Seed Conservation Centre, Botanic Garden of South Australia for providing images of fruits and seeds, and to Peter F. Stevens (Missouri Botanical Garden) for allowing us to use the Angiosperm Phylogeny Website distribution maps.

We thank the beta testers for their helpful comments and suggestions: Keith Clancy, Norma Diaz, Michael Kirkpatrick, Julie McIntosh Shapiro, Jennifer Neudorf, Laura Pottorff, Matthew Sewell, Gregory Stull, Ruojing Wang, and an anonymous reviewer.
