We thank all the Herbaria who have very generously have allowed us to display their images. All images with a RED outline were either provided by the linked Herbaria or given us access to their website to obtain such images, or they were scanned while on loan to us. Please see the credits and further information by clicking on the Herbaria acronyms. The specimens’ images without such red outline, were taken by us during our research visits.

All fruit and seed images have been taken with the Visionary Digital Microscope System, Dun, Inc. Palmyra, VA by Lee Simpson at San Diego State University.
