The Compendium Index (CI) is a one-of-a-kind card catalog that contains illustrations and descriptions of fossil plant species. The CI facilitates identification of fossil plants by arranging these cards into a unique set of numbered morphological categories (e.g., leaf shape and major venation type) that group like-forms with one another regardless of their professed taxonomic assignments.
