Paleobotany Collection:
Catalogs and Information

The UCMP paleobotany catalog (available on-line) contains information on over 26,000 specimens of fossil plants, algae, and fungi. The paleobotany type collection contains specimens which were illustrated or referred to in a publication as representative of a particular form the author(s) studied. Primary types are the specimens chosen as nameholders when a species or subspecies is first described. These include the holotype (the primary nameholder of a species) and paratypes (additional specimens used in the original species description). Secondary types are additional specimens assigned to a species and include primarily hypotypes (those specimens figured) and homeotypes (unfigured specimens). Although the latter type categories are not formally recognized by the International Code of Botanical Nomenclature (ICBN), they generally represent additional well preserved specimens from the original collections. In addition, specimen data and images of UCMP's modern cleared leaf collection are now available on-line. The database has been checked, but may still contain errors.
