*Please note: We are working to resolve issues with pages 23-35 of this project.* The Smithsonian Tropical Research Institute - Center for Tropical Paleoecology and Archaeology invites you to help transcribe specimen cards for the pollen collection. Each of these cards corresponds to a pollen grain on a microscope slide; the data on the cards are invaluable to researchers. Learn how to transcribe these cards with these instructions. Thank you for your help in transcribing them. Please see updated instructions and send your questions on the cards via the Feedback button. We will continue to update these guidelines as we encounter changes in the cards. Thank you!
